Imaging Device Posture Tallying for Region Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the imaged region in medical imaging require initial separate determination of left or right sides and rely on position sensors, which can be cumbersome and require patient positioning.
Innovation Solution
An information processing apparatus that uses posture information from sensors attached to the imaging device to determine whether the imaged region is on the left or right side of the subject by tallying inclination angles and generating distribution information for accurate determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position sensors and predetermined patient positioning are used to determine imaged region, then determination accuracy is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the determination function from complex external systems (position sensors, patient positioning devices) and implements it within the imaging device itself using its existing posture sensors. This eliminates the need for separate determination devices while maintaining accuracy.
Solution Approach 2:
The imaging device performs self-determination of the imaged region using its own posture information and the tallying method. The system serves itself by using internally available data (posture sensors) rather than requiring external measurement systems.
2Measurement precision
If position sensors and predetermined positioning are used, then determination accuracy is improved, but ease of operation worsens due to requiring patient repositioning
Solution Approach 1:
The system automatically determines the imaged region without requiring patient repositioning or manual intervention. The tallying method processes posture information autonomously to identify the imaged region, making the operation simpler and more convenient.
Solution Approach 2:
The system uses real-time posture information from sensors to continuously determine the imaged region during the imaging process. This feedback mechanism allows dynamic adjustment and accurate determination without interrupting the workflow or requiring patient repositioning.
3Measurement precision
If initial separate determination of left or right is performed, then determination accuracy is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary tallying of posture information during the imaging process itself, rather than requiring a separate initial determination step. The determination is integrated into the imaging workflow, eliminating time loss while maintaining accuracy through continuous posture analysis.
Solution Approach 2:
The patent merges the determination function with the imaging process by using posture information collected during imaging. The tallying method combines posture data with imaging timing to simultaneously perform imaging and determination, eliminating the need for separate determination steps.

AI summary
An information processing apparatus includes a memory storing a program, and one or more processors that, by executing the program, function as an obtaining unit configured to obtain information relating to a posture of an imaging device that is imaging a region of a subject, and a determination unit configured to perform a determination, based on the information relating to the posture, regarding which region of the subject corresponds to the region imaged by the imaging device. The determination unit performs the determination based on the information relating to the posture obtained at a timing when a posture of the imaging device satisfies a predetermined condition.
