A model of DICOM-based electronic patient record in radiation therapy.

Electronic patient records for radiation therapy (RT) consists of text, images and graphics. To enable the exchange of RT patient information between systems and institutions, a common standard is called for and the DICOM standard extension to radiation therapy is an appropriate means for standardization. This paper describes a model of DICOM-based electronic patient record system for information exchange and sharing. The system used a DICOM-based RT archive server as a common platform for archival of all RT related information including images and the web technology for distribution and viewing of the patient electronic record.
