Web-Based Information Retrieval and Visualization for Diagnostic Radiology

To improve safety and ease operations in using the medical imaging devices and increase the influx of digital imagery, there is a need for Radiology Information System (RIS) and Picture Archiving and Communication System (PACS) to be used in conjunction to establish a secure network for transmission of patient information. We present a web-based RIS and PACS information retrieval and visualization system implemented for diagnostic radiology, addressing its benefits in workflow improvements, operational efficiencies and convenience for the users. The web application is based on the functional and non-functional requirements elicited on three major user groups, namely, patient, referring physician and radiologist. Novel methodology in the system design and visual analytics is also reported, including Use Case Design, Use Case Descriptions, Database Design, Web Navigation and Activity Diagrams. Experimental results are given to show its effective applications in a clinical setup.
