Modality Apparatus Protocol Change Detection for RIS Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing modality apparatuses in medical facilities face challenges in ensuring that the Radiology Information System (RIS) is aware of the latest imaging protocol changes on the modality side, leading to potential mismatches and inappropriate examination orders.
Innovation Solution
A modality apparatus is designed to detect changes in the combination of intra-imaging protocol sequences and provide updated intra-modality information to the RIS in a predefined format, ensuring that the latest protocol information is used for generating examination orders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RIS checks whether the imaging protocol transmitted and the imaging protocol actually used on the modality side match after imaging, then the imaging process can be completed, but the RIS cannot ascertain the change in the protocol on the modality side until imaging with the changed protocol is performed
Solution Approach 1:
The modality apparatus proactively transmits protocol change information to the RIS before imaging is performed with the changed protocol. This preliminary action allows the RIS to advance the protocol change information in advance, so that when imaging is subsequently performed, the RIS already has updated protocol information and can immediately perform accurate matching without waiting for post-imaging verification.
2Productivity
If the RIS generates examination orders based on outdated protocol information, then the system operation continues, but inappropriate examination orders may be issued
Solution Approach 1:
A feedback mechanism is established where the modality apparatus monitors its own imaging protocol changes and actively notifies the RIS of these changes. The RIS receives this feedback information and updates its protocol information accordingly, ensuring that examination orders are generated based on the latest protocol data, thus maintaining both efficiency and appropriateness.
3Device complexity
If the modality apparatus does not provide protocol change information to the RIS, then the system architecture remains simple, but the RIS cannot generate examination orders based on the latest protocol
Solution Approach 1:
The modality apparatus performs self-service by autonomously monitoring its own imaging protocol changes and independently transmitting this change information to the RIS without requiring external intervention or complex bidirectional communication systems. This self-service approach enables the RIS to adapt to protocol changes while keeping the overall system architecture relatively simple.

AI summary
Provided are a modality apparatus, an information processing method, a program, and a medical information system including the modality apparatus, which can generate an examination order based on information on the latest protocol. A modality apparatus that captures a medical image of a subject according to an examination order includes: a storage device that stores an imaging protocol; and one or more processors configured to, in a case where a combination of intra-imaging protocol sequences of the imaging protocol consisting of a combination of a plurality of sequences is changed, execute processing of providing intra-modality information including the changed information to an information system that generates the examination order in a format defined between the information system and the modality apparatus.
