Web System for Computer Aided Diagnosis for Diabetic Retinopathy Integrated with the Picture Archiving and Communication System

Abstract

This work investigated and implemented the integration and effective use of Computer Aided Diagnostic and Detection systems (CAD) with a Picture Archiving and Communication System (PACS) and how this could provide standardized data and expand the coverage of specialized professionals. Likewise, standardized data allowed interoperability between systems. The designed CAD is focused on Diabetic Retinopathy diagnosis with three main functions: (I) digital image processing for detection, segmentation and extraction of retina image anomaly features, (II) binary classification, and finally (III) converter of the results to the DICOM standard (Digital Imagine and Communication Systems). It was decided to use an open source and free license PACS called Orthanc. The results show the successful integration of the systems, since the studies entered in the CAD are accessed directly from the PACS. At the same time, usability tests show a high degree of efficiency, effectiveness and satisfaction of clinical users in the use of the system.
