Abstract

The SmartScope is a digital microscope designed for pathology applications. Traditional digital pathology methods that rely on a screen and mouse require significantly more time for diagnosis compared to conventional light microscopes. While previous iterations of the SmartScope improved diagnostic time compared to screen-and-mouse methods of digital pathology, early user testing revealed two major challenges: poor image quality and limited adjustability. To address these limitations, we redesigned the SmartScope’s ocular system to incorporate high-resolution SeeYA OLED displays and enhanced adjustability, including interpupillary and vertical tilt adjustments. We conducted a comprehensive literature review of international pathology imaging standards, guiding our selection of screens with high pixel density, contrast ratio, and color accuracy. Our team iteratively refined the mechanical design to ensure user adjustability while protecting, routing, and encasing fragile electronic components. We have validated our work through a series of tests, including thermal analysis and image quality assessments. The new design is expected to improve user comfort and enhance image quality, preparing the SmartScope for the next round of user testing. Along with a working 3D prototype and full Computer-Aided-Design (CAD) documentation for continued work on the oculars, we will also provide a set of recommendations covering material selection, cost optimization, and other key considerations to enhance the design and manufacturing process.
