A Research On DICOM-Support Of Clinical Waveform Equipment

DICOM is a normalized standard for clinical binary data, and now waveform support has been involved. The research of this subject aimed at facilitate waveform equipments' interoperability with other systems, thus we can: Conveniently sharing medical information without bothering about the difference of data format laid down by different vendors; Easily integrated with HIS, PACS; Simplified query/retrieval and management; Greatly improve work efficiency in hospital.For these aims, preliminary research has been carried and DCM-WV software package has been developed:The definition of waveform information object (include haemodynamics waveform and electrocardiogram) has been accomplished. That is the first step to fulfil DICOM-support of waveform equipment. The given waveform information object definition can match the requirement of interoperability between systems, and made it possible for sharing the medical information.Encapsulate module for waveform object instance has been completed. Support nested data set and multi transport syntax, thus can be used in variable environment. These enhanced it's adaptability, and made it easy to integrate with other system.Service class operation has been provided, so that it can communicate with other systems. Can construct and parse message, or store waveform object instance, and also make corresponding response to the received message.PDU service has been offered. PDU services include association, release, abortand data transfer.These are preliminary research on DICOM support of clinical waveform equipment, and there are still detail questions need to be solved (when transplant) in the future.
