Cervical cancer is the second most common gynecologic cancer worldwide. This cancer, unlike the others, does not show any symptoms in its early stage, resulting in increased mortality among women. Cervical cancer can be prevented if effective screening measures are set up. Manual analysis of cytology specimens is extremely tedious, time-consuming and prone to human error, thereby generating the need for computer-assisted tools.OptraSCAN’s CytoSiA offers a plethora of features, in order to effectively screen liquid-based cytology slides, and pap smears to differentiate between normal and abnormal cervical cells. In addition to the cells, infections could be further categorized as reactive, endometrial, actinomyces, candida, clue cells, trichomonas vaginalis, and herpes. It also helps in the identification of entities including blood.
The complex multilayer distribution of cells requires multi-layer/multiplanar scanning – a critical component for morphologic analysis for cytopathologists.Conventional scan routines within a narrow focal range has limitations for Cytology smear slides, as cytology slides have three-dimensional cell groups. This complex multilayer distribution of cells requires multi-layer/multiplanar scanning – a critical component for morphologic analysis for cytopathologists. OptraSCAN’s volume scan routine provides a dual mode for scanning and viewing cytology smears; Z – stacking and extended depth focusing algorithm.
A stack of images is generated at different focal planes along the z- axis. The viewing software enables the user to navigate, zoom up and down the different planes to detect the three-dimensional regions in focus.

Telepathology: A Connection of Hope
The current circumstances owing to coronavirus outbreak; has triggered a need for remote work on a grand scale. The pathologist community needs a solution that’s quick, cost-effective and will facilitate the transfer of image-rich pathology data between distant locations.
In developing economies there are huge gaps in the healthcare system. Few of them being the availability of expert pathologists for consultation during emergencies; especially in rural areas, and challenges involved in physically transporting the slides.
What is Telepathology?
The use of telecommunications technology to facilitate the transmission of image-rich pathology data between two distant locations for research, consultation, education, and analysis purpose.
To practice telepathology, a pathologist must select the images that need to be analyzed and then make an analysis. A pathologist can study the slides remotely in real-time basis and deliver immediate analysis.
Impact of Telepathology
1. Accessibility of Care
Pathology analysis is critical, concerning patient outcomes. The absence of a local pathologist or absence of expert opinion can harm patient health, create delays and costs, and effect surgery choices and planning.
2. Quality of Care
3. Improved Efficiency
How Can Developing Economies Benefit from Telepathology?

Telepathology Is Here to Stay
Needless to say, we as a community will experience more such remote logins in future.
Telepathology is already being practiced to diverging degrees worldwide. Taking advantage of digital solutions laboratories are evolving rapidly and there is an immense opportunity for the field to expand further and unlock complex medical puzzles.
As digital pathology enables collaboration between pathologists as well as within cross-disciplinary teams, pathology labs will be able to offer expertise to regions beyond their current scope where experienced or specialized pathologists are scarce.
Pathologists now need to embrace and take advantage of what these new tools offer in adding objectivity to one’s approach.
It is universally known that Digital Pathology (DP) is the process by which glass slides are digitized to produce high-resolution images. However, the promise of digital pathology and the paradigm shift from microscopy to digitization is not merely transfer of an image from glass slide to a monitor; or to share, modify or analyze the image but rather the potential to transform the digital image by augmenting the human eye with information/data to perform intelligent interpretations (algorithmic approaches) that cannot be gleaned by the pathologist’s eye. These digitized slides afford the possibility of applying image analysis techniques to DP for applications in detection, segmentation, and classification. In short, the next breakthrough innovation in digital pathology could be a next-gen smart scanner, which is driven by artificial intelligence and deep learning concept specially designed for the ease of pathologists to scan, index and analyze the tissue slides – all at the same time.
Algorithmic approaches driven by AI and ML technology, have shown to be beneficial in many contexts as they have the capacity to not only significantly reduce the laborious and tedious nature of providing accurate quantifications, but to act as a second reader helping to reduce inter-reader variability among pathologists. Thus, it aids the pathologist to not only look at many thousand cells but pixels which will enable him/her to perform precise measurements of histological patterns on a whole slide image in his/her precision medicine arsenal. “On the fly image analysis solution” embedded in AI-enabled digital pathology scanner is one such algorithmic approach; a combination of artificial intelligence (AI) and Machine Learning (ML) technology.
Characteristics of smart scanner:
A scanner with AI & ML based technology provides fast and accurate diagnostics support in improving medical research.
Advantage of smart scanner:
These systems offer further advantages by integrating the workflow into the operational environment that is hardware agnostic and lets third parties’ plugins thereby making it a good fit. Augmentation that automatically counts cell types enhances standardization and reproducibility will complement the work of a pathologist by providing more accurate and reproducible analysis of key factors eventually improving patient outcomes.
However, the question bothering the pathology community remains as is! As the technology matures, will computer algorithms outperform human pathologists in both accuracy as well as speed and go beyond assistance, replacing human pathologists eventually? The answer is NO. Artificial intelligence (AI) as a “powerful tool” uses the accuracy of machine learning for complex scoring as well as computational tasks and the cognitive power of the pathologist to analyze complex tissue architecture, each performing to their own strengths. Once in the digital realm, artificial intelligence and deep learning technologies in combination with computational pathology techniques with the humongous data generated will help train deep convolutional neural networks which will mimic the human cognitive capabilities. Multilayered convolutional networks will then perform all complex computational tasks and reveal more information to answer questions about a given disease.
Thus, digital pathology will bring this positive change by replacing the microscope, not the pathologists.
Many healthcare organizations across the globe today are shifting towards digitizing the age-old practice of scanning and viewing glass slides through microscopes. They have realized the potential of digital pathology and digitization of slides that has a direct impact in productivity and efficiency gain. There’s no doubt that digital pathology is bringing a paradigm shift in the way we look at pathology. It is widely regarded for providing accurate cancer diagnosis and bringing the pathology community closer.
However, many organizations are compelled to rely on the conventional microscopy. This could be due to various economic and social factors, ranging from financial constraints to limited internal resources to deploying and managing the system itself!
Although the above-mentioned reasons are inevitable, they should not deter an organization or the pathologists from adopting digital pathology. There are many ways organizations can implement digital scanners as well as avail easy scanning of whole tissue slides in their eco-system, without spending a single buck, upfront!
Digital Lab-as-a-Service (DLaaS) solution:
Digital Lab-as-a-Service is one-of-a-kind solution; wherein Digital Pathology Systems help the pathology labs, hospitals or any healthcare providers to take advantage of digital pathology benefits. Digital Pathology Systems provider will set up a digital infrastructure including whole slide scanners, software, storage servers, etc. within the hospital or lab. Customers will thus pay per scanned slide towards operational expenses post scanning of slides.
Economical Digital pathology scanner offers numerous benefits, such as
Who all can avail Digital Lab-as-a-Service (DLaaS) solution?
Any healthcare organization or healthcare provider can avail the DLaaS, irrespective of their economical condition. However, at a broader level, following could be the benefitting organizations:
The field of immune-oncology biomarker is exploding dramatically. Immunotherapy agents overcome tumor evasion through targeted immune checkpoint inhibitors and scientifically driven combination therapies including multiple immune-stimulating and chemotherapeutic agents. However, not all patients are benefited from immunotherapy and precision medicine requires tremendous understanding of the tumor microenvironment. Complex tissue architecture, heterogeneous biomarker expression as well as visual and cognitive traps affects visual interpretation by pathologists. Moreover, increased requirement of precise diagnostic cut-points of the biomarker measurements poses a problem for pathologists, who are asked to scan thousands of cells in a tissue section and to arrive at a score accurately in order to give a result that can predict a response to the targeted therapy. The promise of digital pathology and image analysis tools help overcome these challenges by performing intelligent interpretations that cannot be gleaned by the pathologist’s eye.
Immuno-Oncology image analysis solutions
Flagship Biosciences developed a platform for understanding the abundance and spatial relationships of different immune cell types and for immune cell clustering using duplex immunohistochemistry. Researchers also adopted HALO platform by Indica labs for digital quantification of PD-L1 tumor cells in melanoma. Another area of concern is the availability of multiple PD-L1 diagnostic immunohistochemistry (IHC) assay and lack of clarity on immunolabelling parameters determined by pathologists and the comparability across assays. A customized Image Analysis scoring PD-L1 scoring solution to permit a quantitative comparison of the 4 PDL1 IHC assays was developed by Definiens that enables to quantify the percentage of positive tumor cells on a whole slide image for 4 PD-L1 assays by co-registration of images and comparing identical areas per case. Aperio Image Toolbox and GENIE image analysis tool (Leica Microsystems) quantifies membrane PD-L1 expression in malignant epithelial cells and macrophages based on Region of Interest analysis.
Optra PD-L1 automated whole slide scoring for tumor and immune cells
Biomarker expression in lymphoid or other immune effector cells is a special challenge for pathologists to measure immune phenotypes, which may predict patient responses to immunomodulating therapies, was observed in the Blueprint 2 study. To overcome the aforementioned challenges, Optra PD-L1 automated image analysis approach generates separate scores for interpretation of PD-L1 IHC expression on both tumor and immune cells without the need of multiple biomarkers for immune cells in the same tissue section in a single read. While all the features/functions are available for integrating, analyzing and collaborating on a single platform; OptraSCAN and image analysis suite can support whole slide scanning, integrated image analysis, image registration and quantification of tumor and/or immune cells based on biomarker content to aid immune-oncology development.
Penetration of digital pathology in North America and Europe in research centers, laboratories, and universities is on rise in the recent years. Digital pathology is predicted to follow the successful path of radiology in near future in terms of acceptance. It has been possible due to obvious advantages over conventional microscopy. The possibility to scan and store the entire tissue slide in digital formats has opened many avenues. The sharing of digital image between pathologists for second opinion or consultation has become easier, faster, and safer. Improvement in communication bandwidth and storage facilities has made Telepathology possible for peer reviews. Overall, pathology workflow has become efficient because of the digitization process. Image processing technology in combination with machine learning and artificial intelligence has revolutionized digital pathology in both qualitative and quantitative assessments.
Challenges in digital pathology adoption:
However, with so many advantages, there is still some reluctancy in adopting digital pathology in both developed as well as emergent nations and there are several factors accounting for the same. The ratio of pathologists to population is already low in developed countries and is much lower in developing countries. Due to this huge gap, a pathologist is overloaded with slides that needs to be scrutinized. The mental fatigue affects the efficiency and accuracy of the pathologist. There are other issues apart from manpower deficiency, such as lack of infrastructure, economic constraints, poor quality control in slide preparation and handling, absence of support systems like LIS to manage the workflow, and a large population that hampers the overall quality of healthcare. There is an apparent increase in cases of non-communicable diseases, including cancer, diabetes, etc., in developing nations that require accurate pathologic diagnosis.
How digital pathology can overcome these challenges?
In rural areas, the absence of trained professionals necessitates expert diagnostic consultation from urban centers equipped with better infrastructure. Movement of physical slides, patients, or professionals for consultation is time consuming and an expensive proposition. This also increases the workload on few professionals in urban settings. Digital pathology can help bridge this gap. Digital Pathology Scanner that offer very competitive scan times and an affordable price tag are the need of the hour in emergent nations. The AI/ML-based quantifying solutions built with digital scanners will complement the pathologist in accurate quantitative analysis of slides. Innovative low-cost solutions like on-demand pathology systems, where the user pays per slide and not for the whole package, are being explored by some pioneers in this field. The IT revolution is already pacing in developing countries, with the advent of smart phones and tablets usage increasing with each generation in both the urban and rural areas. There is tremendous scope of growth for telepathology due to rapid advances in information and technology. Primary diagnosis and training in remote areas, secondary opinions, and referrals could be few of the applications that can be very well addressed by Telepathology effectively.
Role of digital pathology in education & research:
Digital pathology could also be helpful in developing countries in medical schools and universities. The system can improve the training process of technical staff and future pathologists. The digitized slide can be viewed multiple times by as many numbers of students at once. The difficulties like the deterioration of slide quality in terms of stain fading and efforts in maintenance of slides can be removed with easy adoption. The cloud-based systems, where the students and teachers can view the virtual slides will make learning and understanding easier as students and teachers will have access to specialized services like IHC, CISH and FISH, which are otherwise not commonly available in remote areas. With improvements in basic infrastructure like information technology, reliable electrical power, and investment in health care programs, digital pathology can bring myriad changes in improving the healthcare services in emergent nations. In my view, an expert pathologist located at a central clinical setup, receiving virtual slides taken across remote areas (probably through affordable scanners) for his review, would be an ideal healthcare model in developing countries.
Technological innovations continually nurture the process of globalization and the way we deliver healthcare. Telepathology is one such change of delivering remote pathology services and a value-added clinical benefit for better patient care. With its direct effect on healthcare industry, this new paradigm of international telepathology will facilitate cross border collaborations and access to pathology services around the world. Apart from its benefit to the underserved and rural areas in recent years, international teleconsultation has grown and provided a novel source of revenue to pathologists and vendors.
A plethora of such telepathology platforms have been undertaken to serve a multitude of users across the world. One of the earliest was been developed by University of Basel with their global network enabling examination of over 15,000 telepathology cases where static images was the mainstay of image exchange. Virtual International Pathology Network, several telepathology networks established by large academic institutions like University Health Network in Canada, UPMC, MD Anderson in Texas and the Massachusetts General Hospital in Boston are the more recently established providers of expert consultations with adoption of Whole Slide Imaging (WSI). Many commercial vendors with their business partners practicing international telepathology have also started offering telepathology portables e.g Aperio ePathAccess, DP3 platform. Corista, ProNet. XIFIN are a few leading ones. These contemporary telepathology platforms who have adopted WSI enable remote viewing in one of the two ways: either by remote sharing or uploading of images for expert consultations. The former requires strong cooperation between all sectors of the service providers and the latter may suffer delays due to image transmission. Also, these dynamic telepathology platforms are more expensive, and mandate the use of proprietary hardware/software at the receiving and sending end. All the aforementioned challenges hinder interoperability.
Taking advantage of the shift in technology over the past decade, we at Optra have simplified the mode of delivery and have developed an open access platform, TELEPath® with secure, user based logins which supports secure data transfer, patient confidentiality and data encryption accessible even on mobile cellular devices. This hybrid system combines the elements of static, dynamic and real time collaborations which is hardware agnostic without the need for large digital files and image viewer compatibility for different file formats including Z stacked images for interpreting cytology teleconsultations. Key important factors for delivering quality care across borders like quality assurance measures, monitoring timeliness of reporting with a provision for pertinent clinical information, sustainability, flexibility and a bidirectional communication between parties are the currently offered practical solutions to support these collaborations considering the needs of all key stakeholders.
With the draft bill currently before the US Congress to facilitate telemedicine, the practice of international telepathology has a promise to show a positive impact on global patient care.
Over the past few years, deep learning, artificial intelligence (AI) and healthcare AI has become a hot topic owing to development of advanced computer-assisted analytical tools. Pathologists too have embraced this revolution with the recent FDA approval of whole slide scanners. The promise of digital pathology is not merely transfer of analog data from glass slide to a monitor but augment the human eye with information/data to perform intelligent interpretations. AI and deep learning technologies mimic human cognitive capabilities using sophisticated imaging processing techniques to train deep convolutional neural networks. These trained multilayered convolutional networks then perform all complex computational tasks and reveal more information answering queries pertaining to a given disease.
AI/deep learning systems offer further advantages by integrating the workflow into the operational environment that is hardware agnostic, thereby making it a good fit. A larger set of variables can thus be assessed and analyzed by these computer algorithms on the digitized tissue sections. The inevitability of these digital transition AI tools will be particularly beneficial as the industry moves towards value-based payments. Experts in this field suggest that healthcare providers who pay for performance will appreciate the speed and predictive power of AI. Pathology specialty, as prompted by some, will soon metamorphose into a role of “information specialists” to make room for new technologies.
Image analysis algorithms are already being used for automated or semi-automated immunohistochemistry (IHC) quantification, thereby facilitating standardization, speed of analysis and objective reporting to complement the role of the pathologist. Thus, an early intervention towards making AI as an “assisting tool” is combining the human cognitive capabilities and the predictive power of computational algorithms for providing insights into patient specific treatment options.
Intelligent digital pathology will thus bring about a paradigm shift from conventional microscopy to pathology AI.
