Abstract

A method is disclosed for transferring a number of medical image data records from a first computation facility to a second computation facility, with the second computation facility sending a transmission confirmation to the first computation facility after transmission is completed. In at least one embodiment, before the image data records are transmitted, a first checksum is determined for all the image data records and sent with the image data records; the first checksum is extracted at the second computation facility and is compared with a second checksum determined from the transmitted image data records in the same manner as the first checksum; and the transmission confirmation indicates a failure if the checksums do not correspond.

Claims

1. A method for transferring a number of medical image data records from a first computation facility to a second computation facility, the second computation facility sending a transmission confirmation to the first computation facility after transmission is completed, comprising:

determining a first checksum, before the medical image data records are transmitted, for all the medical image data records, the determined first checksum being sent with the medical image data records;

extracting the first checksum at the second computation facility; and

comparing the first checksum with a second checksum determined from the transmitted medical image data records in the same manner as the first checksum, the transmission confirmation indicating a failure if the first and second checksums do not correspond.

2. The method as claimed in claim 1, wherein the medical image data records are in the DICOM format and wherein the first checksum is sent as private content of one of the medical image data records.

3. The method as claimed in claim 1, wherein the medical image data records are processed for at least one of send and receive purposes by a pipeline having at least one filter, at least one of the determination of the checksum and the comparison of the first and second checksums forming such a filter.

4. The method as claimed in claim 1, wherein the medical image data records are at least one of compressed and encoded in the first computation facility after determination of the first checksum and the determination of the second checksum takes place after at least one of decompression and decoding.

5. The method as claimed in claim 1, wherein a transmission confirmation according to the DICOM standard is used.

6. The method as claimed in claim 1, wherein a computation facility of an image recording facility is used as at least one of the first computation facility and a computation facility at a diagnostic workstation or a computation facility of an image management system is used as the second computation facility.

8. The method as claimed in claim 2, wherein the first checksum is sent as private content of a relatively last one of the number of medical image data records.

9. The method as claimed in claim 2, wherein the medical image data records are processed for at least one of send and receive purposes by a pipeline having at least one filter, at least one of the determination of the checksum and the comparison of the first and second checksums forming such a filter.

10. The method as claimed in claim 8, wherein the medical image data records are processed for at least one of send and receive purposes by a pipeline having at least one filter, at least one of the determination of the checksum and the comparison of the first and second checksums forming such a filter.

11. The method as claimed in claim 5, wherein the transmission confirmation comprises a failure flag.

7. A system for managing medical image data records, comprising:

at least two computation facilities, configured to

determine a first checksum, before medical image data records are transmitted from a first of the at least two computation facilities to a second of the at least two computation facilities, the determined first checksum being sent with the medical image data records;

extract the first checksum at the second computation facility; and

compare the first checksum with a second checksum determined from the transmitted medical image data records in the same manner as the first checksum, a transmission confirmation indicating a failure if the first and second checksums do not correspond.

12. A non-transitory computer readable medium including a computer program product, the computer program product comprising instructions, which when executed on a computer, causes the computer to perform functions including:

determining a first checksum for all the medical image data records, before a medical image data records are transmitted from a first computation facility to a second computation facility, the determined first checksum being sent with the medical image data records;

extracting the first checksum at the second computation facility; and

comparing the first checksum with a second checksum determined from the transmitted medical image data records in the same manner as the first checksum, the second computation facility sending a transmission confirmation to the first computation facility after the transmission is completed, the transmission confirmation indicating a failure if the first and second checksums do not correspond.
