Paper Abstract

Computer Aided Diagnosis (CAD) coupled with physician's knowledge can improve accuracy of clinical decision. However, many developed CAD software have no features to integrate its results with a picture archive and communication system (PACS). This obstacle hinders the extensive use of independent CAD results within a more streamlined diagnosis workflow. In this paper, we demonstrate a universal PACS-CAD toolkit that can seamlessly integrate independent CAD results with a clinical PACS. The PACS-CAD toolkit consisted of two versions, a DICOM Secondary Capture (DICOM-SC) version and a DICOM-IHE version to accommodate various PACS. The DICOM-SC version toolkit installed on a CAD workstation converts the screen shot of CAD results to a DICOM image file for storing in a PACS server and displaying on PACS workstations. The DICOM-IHE version toolkit follows DICOM and IHE standards using DICOM Structured Report and Post-Processing Workflow Profiles; thus, results from various CAD software can be integrated into diagnosis workflow of a PACS having DICOM and IHE-compliance and, most importantly, these quantified CAD results can be directly queried for and retrieved from within PACS for future data mining applications. The successful implementation of this toolkit can greatly ease the extensive use of various CAD results in the clinical diagnosis workflow.
