VSI images: Frequently Asked Questions
What are VSI files?
VSI stands for Virtual Slide Image, a proprietary file format developed by Olympus for storing high-resolution digital pathology slides. VSI files are generated by Olympus virtual slide scanners and used primarily in medical imaging, histology, and research applications where detailed examination of microscope slide scans is required. A VSI file typically contains a large, multi-layered image that allows for zooming and panning, similar to how a microscope would be used to view tissue samples at varying magnifications.
