Digital Pathology is a dynamic, image-based environment that enables the acquisition, management and interpretation of pathology information generated from digitizing a pathology glass slide. Compared to the traditional microscope-based pathology diagnosis with glass slides, digital pathology allows pathologists to view digitized slides remotely through a network without using a microscope. Moreover, pathologists can utilize various imaging analyzing software to do a more quantitative and objective diagnosis for these digitized slides. With such advantages, digital pathology is expected to revolutionize the workflow of pathology department in hospitals and offer the public better and faster diagnostic service. The current technology barriers for general adaption of digital pathology include long digitization time, large image data size and high system cost. The objective of this project is to develop new technologies to speed up the slide digitization process. Our research effort will be focusing on two main directions: (i) a new optical design to increase the field of view of the imaging system to reduce the number of tiles required for each whole slide imaging; (ii) a new mechanical design to increase the response speed of the focusing system to reduce the time spent on achieving good focus for the whole slide.
