An ultra-high speed Whole Slide Image viewing system

Area of Science:

• Digital Pathology
• Medical Imaging Technology

Background:

• Whole Slide Imaging (WSI) systems aim for clinical pathology integration.
• Current WSI systems face challenges with viewing speed, impacting diagnostic efficiency.
• User satisfaction with WSI viewing speed remains a critical unmet need.

Purpose of the Study:

• To evaluate a novel, high-speed Whole Slide Imaging (WSI) viewing station.
• To assess the usability and speed of a prototype WSI viewer for clinical pathology applications.

Main Methods:

• A prototype WSI viewer was developed using a PlayStation®3 and wireless controllers.
• The system was evaluated at Massachusetts General Hospital (MGH) Department of Pathology.
• Evaluations included simulated case sign-outs, consensus conferences, and Continuing Medical Education slide seminars.

Main Results:

• Pathologists required minimal training (0-15 minutes) to comfortably use the system.
• No speed-related complaints were reported by users.
• High satisfaction was reported regarding system functionality, usability, and speed.
• Simulating diagnostic sign-out presented the most challenging scenario.

Conclusions:

• Adapting the Sony PlayStation®3 as an ultra-high speed WSI viewing system yielded promising preliminary results.
• The demonstrated speed is adequate for the demands of daily clinical pathology practice.
• The prototype WSI viewer shows potential for improving efficiency in digital pathology workflows.
