Radiation Imaging Mode Switching for Positioning and Imaging Time
Solution Overview
Problem
Existing radiation imaging systems struggle to effectively manage two-step imaging for different imaging attributes with varying possibilities of failure, leading to unnecessary radiation exposure due to improper execution or misunderstanding of pre-image display settings.
Innovation Solution
A radiation imaging system with a hardware processor that executes pre-imaging at a lower dose, derives imaging conditions based on the pre-image, and switches between pre-image checking and short-time imaging modes to ensure appropriate positioning and minimize radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pre-image is displayed after pre-imaging for checking positioning, then positioning accuracy is improved, but imaging time is increased
Solution Approach 1:
The system dynamically switches between pre-image checking mode and short-time imaging mode based on imaging attributes and failure possibilities. This dynamic adaptation allows the system to optimize between positioning accuracy and imaging time for different clinical scenarios, resolving the contradiction by making the pre-image display conditional rather than fixed.
Solution Approach 2:
The system changes the parameter of pre-image display (displayed/not displayed) based on imaging attributes and calculated failure possibilities. By adjusting this parameter dynamically according to specific imaging conditions, the system achieves optimal balance between positioning verification and imaging efficiency for different clinical cases.
2Productivity
If pre-image is not displayed to shorten imaging time, then imaging efficiency is improved, but reliability is reduced
Solution Approach 1:
The system dynamically adjusts whether to display pre-image based on real-time assessment of imaging attributes and failure possibilities. This dynamic approach ensures that pre-image checking is performed only when necessary for reliable positioning, maintaining imaging reliability while maximizing efficiency for routine cases where positioning is less critical.
Solution Approach 2:
The system uses feedback from imaging attributes and automatic positioning assessment to determine whether pre-image display is needed. This feedback mechanism ensures that positioning reliability is maintained when necessary while avoiding unnecessary delays in cases where the positioning is expected to be accurate based on pre-assessment.
3Extent of automation
If pre-image display is automatically controlled without user notification, then system automation is improved, but user awareness is reduced
Solution Approach 1:
The system provides feedback to the user by notifying them of the control mode (pre-image checking mode or short-time imaging mode) before execution. This feedback ensures that users are aware of what will happen next, preventing misunderstandings while maintaining automated control of the actual imaging process.
Solution Approach 2:
The system uses mode notification as an intermediary communication between the automated control system and the user. This intermediary information bridge ensures that users understand the system's intended actions without requiring manual control, resolving the contradiction between automation and user awareness.
Data Source
AI summary
A radiation imaging system includes a first hardware processor. The first hardware processor executes control such that, before main imaging is executed at a main dose, pre-imaging is executed at a pre-dose that is lower than the main dose. The first hardware processor derives an imaging condition for the main imaging based on a pre-image acquired in the pre-imaging, switches a control mode to one of a pre-image checking mode and a short-time imaging mode, and notifies which control mode between the pre-image checking mode and the short-time imaging mode is used to execute the control. The pre-image checking mode being a mode in which the pre-image is displayed after executing the pre-imaging. The short-time imaging mode being a mode in which the pre-image is not displayed after executing the pre-imaging before the main imaging.
