Medical Image Transfer Checksum Verification for Storage Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical image data transfer methods lack assurance of successful transmission and storage, as the DICOM standard's storage commitment service is underutilized, leading to potential data loss due to incomplete confirmation of image data records being archived or stored.
Innovation Solution
Incorporating a checksum mechanism where a first checksum is calculated and sent with the image data records, and a second checksum is calculated upon receipt, allowing for comparison to confirm failure-free transmission without additional messages or modifying the existing transmission mechanisms, ensuring data integrity and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage commitment service is used to confirm successful transmission, then data reliability is improved, but transmission performance deteriorates due to additional messages
Solution Approach 1:
The patent combines the transmission confirmation message with the storage commitment verification by including the checksum result within the existing transmission confirmation framework. This merging eliminates the need for separate verification messages while maintaining both transmission performance and reliability confirmation.
Solution Approach 2:
The patent introduces a checksum as an intermediary element that enables verification of data integrity without requiring additional communication overhead. The checksum acts as a mediator that can be verified unilaterally by the receiving system, eliminating the need for interactive confirmation messages.
2Productivity
If early transmission confirmation is sent immediately after receipt, then transmission performance is improved, but data reliability deteriorates as storage success cannot be confirmed
Solution Approach 1:
The patent performs preliminary calculation of the checksum and includes it with the transmitted data. This preliminary action enables the receiving system to verify data integrity immediately upon receipt without requiring additional confirmation messages, thus maintaining both speed and reliability.
3Reliability
If checksum is sent with image data records, then transmission verification is improved, but device complexity increases due to additional processing
Solution Approach 1:
The patent implements a self-service verification mechanism where the checksum is automatically calculated, attached to the data, and verified by the receiving system without requiring external verification infrastructure. This self-service approach maintains simplicity while enabling reliable verification.
Data Source
AI summary
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.
