Abstract

The present invention relates to a DICOM-based 12-lead ECG gateway and browser for use in clinical information system.

Claims

1. A data processing system of 12-Lead DICOM ECG that integrates with HIS or PACS, comprising:

(a) a decoding and signal processing device that automatically retrieves SCP-ECG or XML-ECG used in a clinical ECG instrument;

(b) a device which converts the decoded ECG signals to DICOM-ECG;

(c) an ECG processing unit of 12-Lead DICOM ECG information management system, which receives signals from HIS or transmits DICOM-ECG to PACS; and

(d) a 12-Lead DICOM-ECG browser that is switched on using HIS or PACS.

2. The system of claim 1, wherein the decoding device of SCP-ECG comprises:

(a) a device for processing the decoding of sections 0, 1, 8, 128; and

(b) a device for processing Huffman decoding.

3. The system of claim 1, wherein the decoding device of XML-ECG comprises:

(a) a device for reading report information (reportinfo tag), data acquisition information (measurements tag), patients'"'"' information (patient tag), interpretation information (interpretations tag) and waveforms information (waveforms tag); and

(b) a signal-processing device.

4. The system of claim 2, wherein obtained data from the decoding device are transformed into ECG signals by stationary wavelet conversion.

5. The system of claim 4, wherein the ECG signals comprise raw data of ECG waveforms or ECG diagnostic information.

6. The system of claim 4, wherein the ECG diagnostic information comprises an accession number, name, gender, date of examination, time of examination, or ECG diagnosis result of individual patients.

7. The system of claim 3, wherein obtained data from the decoding device are transformed into ECG signals by stationary wavelet conversion.

8. The system of claim 7, wherein the ECG signals comprise raw data of ECG waveforms or ECG diagnostic information.

9. The system of claim 7, wherein the ECG diagnostic information comprises an accession number, name, gender, date of examination, time of examination, or ECG diagnosis result of individual patients.

10. The system of claim 1, wherein the device which converts the decoded ECG signals to DICOM-ECG further comprises generation of a core file and an index file.

11. The system of claim 10, wherein the core files are subdivided into the format conversion of SCP-ECG core files and XML-ECG core files.

12. The system of claim 11, wherein the format conversion of SCP-ECG core files sequentially comprises signal length extension, sequence order swapping, lead order swapping, signal length calculation, and the writing of waveform lengths, level lengths or waveform data.

13. The system of claim 11, wherein the format conversion of XML-ECG core files sequentially includes lead order swapping, signal length calculation, and the writing of waveform lengths, level lengths or waveform data.

14. The system of claim 10, wherein the index file utilizes the ECG diagnosis information to write custom tags, patient information or retrieves time and date.

15. The system of claim 1, wherein the ECG processing unit of 12-Lead DICOM ECG information management system is a device which stores files in PACS and reports completion of diagnosis and communication with the information page to the HIS

16. The system of claim 15, wherein the PACS is used to integrate DICOM files in medical institutes.

17. The system of claim 1, wherein the DICOM-ECG browser is linked to PACS or HIS system for remote operation.

18. The system of claim 17, wherein the operation comprises creating new files, opening old files, saving files, printing, magnifying, shrinking or moving the files.
