Image diagnosis systems (IIIM)

Computer Aided Diagnosis System

The target of our research group is to implement a computer aided diagnosis (CAD) system to increase the accuracy of clinical image diagnosis and to reduce radiologists’ workload. To implement the system, we are investigating diagnostic process by radiologists, as well as developing image processing techniques and decision support systems. Our group has successfully developed a new storage system for a huge amount of three dimensional image data, which are indispensable for our research. This system has high throughput at loading data, search capability, facility for research, and has been operating for more than three years, which has resulted in more than 70TB of stored data. We are currently working on technological developments to implement an integrated computer aided diagnosis (CAD) and reporting system. To develop a prototype, we are now focusing on diagnosis of pulmonary nodules in CT. To infer diagnosis, this system uses not only image features calculated with image processing techniques, but also findings by radiologists, laboratory data, patient history and so on. To assist radiologists, this system indicates inferred diagnoses, reasons for each diagnosis, as well as automates writing reports. We believe that the application of this system will have a strong impact on diagnostic imaging in the future.

Automatic segmentation of three dimensional regions of pulmonary nodules, and feature analysis of the regions.
