Body Motion Display Device for Radiographic Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting body motion in radiographic images during photography are inefficient, requiring technicians to manually confirm motion across multiple regions of interest, which degrades workflow and image quality.
Innovation Solution
A body motion display device and method that calculates an index value representing the degree of body motion across a radiographic image and selectively displays relevant information, such as marks or vectors, based on these values to efficiently identify and visualize body motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple regions of interest are displayed with body motion detection results, then body motion can be detected in each region, but the operation for confirming body motion becomes inefficient and time-consuming
Solution Approach 1:
The patent extracts only the essential body motion information from multiple regions of interest and displays it selectively. Instead of showing all detection results for all regions, the system identifies and displays only the regions where body motion is detected, thereby reducing the time required for confirmation while maintaining detection accuracy.
Solution Approach 2:
The patent segments the radiographic image into multiple regions of interest and processes each region independently. By dividing the image into distinct regions, the system can efficiently detect body motion in each region and selectively display only those regions where motion is present, rather than requiring manual review of the entire image.
2Difficulty of detecting and measuring
If the radiographic image is displayed on a magnified scale, then body motion can be confirmed more easily, but the technician must search for the portion containing body motion, degrading workflow efficiency
Solution Approach 1:
The patent introduces body motion information (such as detection results, probability values, or visual markers) as an intermediary between the radiographic image and the technician's judgment. This intermediary provides direct indication of where body motion is present, eliminating the need for the technician to manually search through magnified images and improving workflow efficiency.
3Loss of information
If all body motion information from multiple regions is displayed, then complete information is provided, but excessive information display occurs, reducing efficiency
Solution Approach 1:
The patent extracts and displays only the relevant body motion information from multiple regions of interest. Instead of showing all detection data for every region, the system identifies regions where body motion is present and displays information specifically for those regions, thereby maintaining information completeness for critical areas while reducing overall information load and improving confirmation efficiency.

AI summary
Disclosed are a body motion display device and a body motion display method which efficiently performs operation for confirming the presence or absence of body motion included in a radiographic image. An index value calculation unit calculates an index value representing body motion based on the ratio between contrast of a high-frequency component and contrast of a low-frequency component in a radiographic image at an analysis point set by an analysis point setting unit. A display control unit selectively displays, on a display unit, at least one of a plurality of kinds of body motion information based on index values at a plurality of analysis points.
