A Gateway Between The Non-dicom Standard Ecg Equipment And Pacs System

As medical environments become more integrated and complicated, variousmedical data are collected together for integrated diagnoses. The medicalenvironments involving images and cardiology waveforms are very usual, e.g. cardiaccatheterization laboratory. In these multi-device environments, digital imagingdevices should communicate with digital waveform devices to exchange and share theimages and waveforms. To resolve this interoperability problem, the best way is thatthe same data format and communication protocol are used.DICOM is an international standard just for these needs, and it has been used toresolve the problems in practice. Based on the DICOM standard, PACS is one of themost important hospital information systems. Nowadays, DICOM is not only used forimages communication, but also for the exchange of medical waveforms.This thesis discusses the connection of ECG devices and PACS conformable toDICOM. For the PACS connection of non-DICOM ECG devices, a DICOM gatewayis need between ECG devices and PACS. Among various non-DICOM ECG formats,the SCP-ECG is the European standard for communication of resting ECGs.SCP-ECG is widely accepted by ECG manufacturers, so the gateway betweenSCP-ECG and PACS is particularly valuable.The study work is focused on the design and development of the DICOM gateway,including:1. Analyze the DICOM information model and DICOM network protocol architecture.2. Based on the architecture of PACS, design the architecture and the modules of the gateway system. The gateway is composed of three modules, which are file conversion, ECG display and file transfer.3. Implement the modules of gateway. The file conversion module and ECG display module are implemented according to SCP-ECG file format and DICOM file format. The file transfer module is implemented based on DICOM network protocol architecture.The work is expected to resolve the PACS integration of ECG devices, contributeto the harmonization of ECG standards, and facilitate digital ECG interoperability.
