OptraSCAN’s Z-Stack
and Extended depth of field volume scan solution for Cytology
Multiplanar/Multilayer scan:
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.
- Z-Stacking technology:
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. - Extended depth of field:
Volume scan using z-stacks is expensive in terms of scan time and size due to its multilayer nature. OptraSCAN’s extended depth of field algorithm generates a single, entirely focused composite image to effectively, easily and systematically screen an entire image.
Advantages:
- Relatively smaller file size than multiplane images.
- Quicker to acquire.
- Effective and easy navigation for accurate interpretation, sharing and archiving.
Features of OptraSCAN’s volume scanning technology:
- Fully automated multiplayer scanning at different focal depths.
- Automated and User configurable focal intervals for Z stacking
- Ideal for Rapid On-site evaluation for adequacy of cytology samples (Rapid on-site evaluation (ROSE)
