Transfer Syntax Extension of the Compressed EECP Waveforms Based on DICOM Standard

The development of Enhanced External Counter-pulsation (EECP) LAN system and XML-based remote EECP Medical Information system conformable to DICOM Standard has been improving the digital interchangeable and sharable of EECP v. The therapy of EECP is a continuous and longtime supervision which builds a mass of waveform data. In order to reduce the storage space and improve the transmission efficiency, the waveform data has to be compressed. In DICOM Standard, there´s no detail description or normative transfer syntax for compressed waveform data. So the article introduced the compression arithmetic and storage of EECP waveform data based on DICOM Standard. The private transfer syntax is defined according to the rules of DICOM normative transfer syntaxes. Testing results indicate that the compressed data can be correctly transmitted and displayed between EECP workstations in our EECP Laboratory.
