Introduction to this document
Introduction to this document For a number of years, the International Electrotechnical Commission (IEC) worked on the development of a standard addressing Electronic Data Exchange in Radiotherapy. At about the same time, another group with international representation had been working to extend the DICOM (Digital Imaging and Communication in Medicine) standard initially used for diagnostic images to include images/data used in radiotherapy. Ultimately, a decision was made by the IEC to adopt four DICOM RT objects as an IEC standard which appeared in April 1998 as IEC 61852 'Medical Electrical Equipment - Digital Imaging and Communication System in Medicine (DICOM) - Radiotherapy Objects First Edition'. The present document has been developed to introduce and to call attention to the complexity of the DICOM standard with its radiotherapy extension. It also addresses the importance of a complete evaluation of the "DICOM Conformance Statement" prepared by manufacturers, and the need for a qualified individual such as a medical physicist to evaluate the compatibility of pieces of radiotherapy equipment impact in the clinic of electronic data transfer, and the integrity of data exchange.
This document gives a brief introduction to DICOM including its extension to Radiotherapy. Parts of this document are derived from the brochure produced by the DICOM WG 7 responsible for producing the RT extension to the DICOM Standard. This document outlines preliminary steps required to implement and test a DICOM interface to a medical application system.
The DICOM standard has been published(1a) by the National Electrical Manufacturers Association of America. Based on this standard there are a number of DICOM development tool kits produced by academia and available in the public domain. There are also commercial toolkits produced by a number of vendors. Details of these can be obtained on the Internet. The DICOM newsgroup(1b) on the Internet provides state of the art news on DICOM Standard development, related products, problems etc. Some of the Internet references have links to other companies' DICOM-related Web sites which are extremely useful for further information on DICOM related subjects.
NOTE This document is an implementation guide. For full normative description of the DICOM standard consult the official standard(1a).
