Chapter 4: Scan Slides
Image Quality Control for Histotechnicians and Pathologists
After scanning slides, it is important to review the digital slides to make sure the images are of
good quality. Ultimately, it is up to the pathologist to look at digital slides to verify they are of
sufficient quality to perform their task. In addition, scanner operators should verify digital slide
quality after scanning.
The quality criteria that are important for primary diagnosis and that should be verified by
scanner operators are: 1) that the entire tissue sample has been scanned, and 2) that the tissue
is in focus.
Aperio scanners provide a macro image, a low-resolution image of the entire slide, that also
provides a green outline of the scanned image. Check that image for the quality criteria
mentioned above.
Re-scan any slides that failed to scan or failed the image quality review.
For additional image quality assessment instructions, refer to the user guide for your viewer.
