Design and Validation of a Low-Cost Telepathology System.

Objective: This work sought to evaluate the precision and repeatability of a telepathology prototype based on open software and hardware.

Materials And Methods: A prototype was designed with application in telepathology and telemicroscopy. Accuracy and prototype precision were evaluated by calculating the mean absolute error and the intraclass and repeatability correlation coefficients for a series of 190 displacements at 10, 25, 50, 75, and 100 μm.

Results And Conclusions: This work developed a low-cost prototype that is accessible, easily reproducible, implementable, and scalable; based on the use of technology created under principles of open software and hardware. A pathologist reviewed the obtained images and found them to be of diagnostic quality. Its excellent repeatability, coupled with its good accuracy, allows for its application in telemicroscopy and static, dynamic, and whole-slide imaging pathology systems.
