SpectralHT
Pramana's SpectralHT is an advanced digital scanning solution for high throughput digitization of glass slides.
Product Highlights
Truly automated whole slide image scanning
Intelligent scanning software
Autonomous in-line quality control
Standards based output
Scalable solution designed for high volume projects
Features
High Tolerance to Common Challenges with Specimens
SpectralHT produces high quality Whole Slide Images while detecting a variety of artifacts like annotations, debris, broken coverslip, stain deposits, bubbles, folds, uneven staining, very faint tissue, scratched glass etc, and do in-line optimization to produce superior quality WSIs.
Rapid Loading and Unloading
The scanning clusters have been designed to achieve rapid operations. Up to 5 scanning clusters can be managed by a single operator for loading, unloading, operation, and sign-off for viewing by pathologists.
Automated Quality Checks
SpectralHT comes with embedded automated QC, that can not only assess the quality of WSIs in a quantitative manner, but can also do inline re-scans to produce high quality images. This eliminates the cost and time required to perform manual quality checks on the output, before consuming them for any downstream purpose. Pramana scanners produce WSIs with less than 0.5% imaging errors, 99% of time. See our Joint Poster with Memorial Sloan Kettering on this topic here.
