Radiation Imaging Protocol Replacement via Dynamic Parameter Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging systems face inefficiencies in replacing imaging protocols due to the need for manual operation and extensive lists of substitute candidates, leading to increased time and effort in selecting the correct protocol, particularly when correcting errors such as 'left' and 'right' body part or irradiation direction.
Innovation Solution
A radiation imaging system that includes processors and memory to obtain a first imaging protocol, search for and display user interfaces for selecting a second protocol differing in specific parameters, and replace the first protocol based on operator instructions, thereby simplifying the protocol replacement process without requiring pre-registration of all substitute candidates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all substitute candidate protocols are registered in advance to cover all possible errors, then the system can handle any imaging protocol replacement scenario, but the number of substitute candidates becomes enormous and registration time and effort increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically generating substitute candidate protocols through parameter modification based on error patterns, rather than requiring manual registration of all possible substitutes in advance. This reduces registration time while maintaining comprehensive coverage.
Solution Approach 2:
The system serves itself by automatically generating substitute protocols when errors are detected, using built-in error pattern recognition and parameter modification capabilities. This eliminates the need for extensive manual pre-registration of substitute candidates.
2Adaptability or versatility
If all substitute candidate protocols are registered in advance, then any imaging error can be corrected, but the number of choices excessively increases making it difficult to search and select the desired protocol
Solution Approach 1:
The system extracts only the necessary substitute protocols dynamically based on detected errors, rather than presenting all possible substitutes. This is achieved by identifying specific error types and generating only the relevant protocol modifications, reducing the number of choices while maintaining correction capability.
Solution Approach 2:
The substitute candidate list is made dynamic, changing based on the detected error type and current imaging protocol. The system adapts the presented options in real-time based on the specific situation, making the interface more manageable and easier to navigate.
3Ease of operation
If substitute candidate protocols are limited to representatives, then the number of choices is reduced, but it becomes difficult to correct specific mistakes such as 'left' and 'right' body part errors
Solution Approach 1:
The system modifies specific parameters of the imaging protocol based on detected errors, such as changing laterality parameters for left/right mistakes or direction parameters for irradiation errors. This allows precise correction of specific mistakes while maintaining a limited set of representative substitute candidates.
Solution Approach 2:
The system applies localized modifications to specific parameters of the imaging protocol rather than replacing the entire protocol. This enables targeted correction of specific errors (e.g., only changing the laterality parameter for left/right mistakes) while keeping the rest of the protocol intact.
4Adaptability or versatility
If manual operation is used to search and select substitute protocols, then flexibility in selection is maintained, but time and effort are significantly increased
Solution Approach 1:
The system uses feedback from error detection to automatically generate and present relevant substitute protocols. The error detection mechanism provides information about the specific mistake, and this feedback drives the automatic generation of appropriate corrections, reducing manual search time while maintaining selection flexibility.
Solution Approach 2:
The manual mechanical process of searching through protocol lists is replaced with an automated information processing system that detects errors and generates substitute protocols algorithmically. This substitution dramatically improves efficiency while preserving the ability to review and select from generated options.

AI summary
A radiation imaging apparatus includes one or more processors and one or more memories storing, as one or more computer programs, computer-readable instructions to be executed by the processors to be performed a process including: obtaining a first imaging protocol including one or more parameters concerning radiation imaging; searching a plurality of imaging protocols stored in a storage unit for a second imaging protocol differing in some parameters from the obtained imaging protocol; causing a display unit to display a user interface for selecting an imaging protocol as a replacement destination of the first imaging protocol from the second imaging protocol specified when the second imaging protocol is specified by the process of searching; and replacing the first imaging protocol with the selected second imaging protocol in accordance with an instruction from an operator to the user interface.
