DICOM Imaging Station Data Transmission Acknowledgment Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In DICOM standard communication systems, network communication failures due to reasons like interface failures, station restarts, or interrupts can interrupt the transmission of medical data sets between imaging stations, leading to incomplete or failed data transfers.
Innovation Solution
A method and system that select medical data for transmission, check for acknowledgement signals, and retransmit if no signal is received, ensuring successful data transfer by storing acknowledgement signals in the memory of the first imaging station, allowing for resumed transmission from interrupted points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network communication is established for transmitting medical data between imaging stations, then data transfer capability is improved, but transmission reliability deteriorates due to network failures, station restarts, or interrupts
Solution Approach 1:
The system performs preliminary actions by checking for the presence of acknowledgment signals before transmitting medical data. The transmitting station checks its memory for stored acknowledgment signals from receiving stations, and only transmits data for which no acknowledgment is found. This preliminary check prevents redundant transmissions and ensures reliable data transfer even after network interruptions or station restarts.
2Reliability
If acknowledgment signals are stored in memory to track successful transmissions, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The system uses a simplified copying approach by storing only acknowledgment signal indicators in memory rather than complete transmission state information. Each transmitted data set receives a unique identifier, and the system merely stores whether an acknowledgment was received for each identifier. This minimal copying approach tracks transmission status without requiring complex data structures or extensive memory resources.
3Loss of information
If the system checks for acknowledgment signals before each transmission, then data loss is reduced, but transmission time increases
Solution Approach 1:
The system extracts and stores only the essential acknowledgment signal information in memory - specifically, whether an acknowledgment was received for each transmitted data set identifier. This extraction of minimal necessary information allows the system to quickly check transmission status without processing or storing complete transmission logs, thereby reducing the time overhead of acknowledgment checking while still preventing data loss.
Data Source
AI summary
A method of transmitting a data set comprising at least one medical data from a first imaging station to at least one other imaging station via a network interface in a DICOM standard communication system is provided. The method comprises the acts of selecting a first medical data from the data set for transmission; checking a memory of the first imaging station for a receipt of an acknowledgement signal indicative of a successful transmission of the first medical data to the at least one other imaging station; transmitting the medical data if the act of checking does not detect the receipt of acknowledgement signal; receiving the acknowledgment signal from the at least one other imaging station in response to a successful receipt of the first medical data at the at least one other imagine station; and storing the receipt of acknowledgement signal in the memory of the first imaging station.
