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.

1. 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.
2. 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:

1. Relatively smaller file size than multiplane images.
2. Quicker to acquire.
3. Effective and easy navigation for accurate interpretation, sharing and archiving.

Features Of Optrascan’s Volume Scanning Technology:

1. Fully automated multiplayer scanning at different focal depths.
2. Automated and User configurable focal intervals for Z stacking
3. Ideal for Rapid On-site evaluation for adequacy of cytology samples (Rapid on-site evaluation (ROSE)
