A whole slide image (WSI) is accomplished by digital scanning and allows online viewing of your entire stained section.
The VS200 can scan histology slides stained for brightfield imaging (H&E, PAS, special stains) or with fluorescent antibodies. Standard 1″x3″ slides and larger 2″x3″ slides can be scanned. Can scan up to 210 standard slides automatically.
More information about the MPC Olympus VS200 can be found here. This scanner was awarded through an NIH Shared Instrumentation Grant and installed in November 2023.

Prepare Slides
Best results are obtained with a #1.5 thickness coverslip and tissues with even thickness (4-5um).
Slides must be completely dry- do not scan wet slides.
Best scanning results will be obtained from glass slides with #1.5 thickness coverslips and regular thickness (4-5 microns) tissues. Slides with marks (such as ink dots), extra mounting medium, non-glass slides, plastic coverslips, thick labels, and labels that are going around the slide present challenges for automatically finding the tissue and proper imaging. These artifacts may need to be removed to obtain an optimal scan. Images are individually reviewed once the scanning is completed. Scans with poor quality will be rescanned manually to achieve the maximum quality possible. The equipment can not scan slides with wet mounting media, more than two slide labels, labels on the back or the bottom of the slide, double slides, or broken slides. The slide and coverslip should be free of fingerprints, dust, and dirt. Any pen markers on the slide also need to be removed as the scanner will consider such marks as tissue. Faint stains, air bubbles, thick sections (> 50um), or marks on the glass surface can cause lower scan quality. In some cases, sample recut or restaining may be recommended.
