Ultrasound Diagnostic Apparatus with Camera-Based Motion Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasound diagnostic apparatuses face challenges in accurately inspecting the mobility of moving body parts, such as joints or tendons, as inspectors need to simultaneously visualize both the subject's movement and ultrasound images, making it difficult to recognize the linkage between the two.
Innovation Solution
An ultrasound diagnostic apparatus that generates ultrasound images based on reception signals and detects subject movement through camera image analysis, then integrates this information into the display, changing the display content or mode to enhance visualization of the moving body part's mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the inspector visually recognizes both the actual movement of the subject and the ultrasound image simultaneously, then the mobility of the moving living body part can be inspected, but it is hard to recognize the linkage between the movement of the subject and the motion of the moving living body part
Solution Approach 1:
The patent merges the ultrasound image display with camera image display into a single integrated display interface. The ultrasound image and camera image are shown simultaneously on the same monitor, allowing the inspector to view both the internal tissue movement and external subject movement together. This integration enables direct visual correlation between subject movement and tissue mobility without requiring switching between separate displays.
Solution Approach 2:
The camera acts as an intermediary that captures and displays the external movement of the subject alongside the ultrasound images. By introducing the camera image as a mediating visual element, the system bridges the gap between internal tissue motion and external subject movement, making the linkage between them visually apparent and easier to interpret.
2Loss of information
If the inspector switches between ultrasound and camera images to recognize subject movement and tissue motion, then both pieces of information can be obtained, but the inspection efficiency decreases
Solution Approach 1:
The system combines multiple information sources (ultrasound images and camera images) into a single unified display. This merging eliminates the need for inspectors to switch between separate displays or windows, allowing simultaneous viewing of all relevant information and thereby improving inspection efficiency without sacrificing information completeness.
Solution Approach 2:
The patent adds a new dimension to the display by incorporating camera images alongside ultrasound images. This multi-dimensional presentation approach allows inspectors to access both internal tissue information and external movement information in a single integrated view, eliminating the need to switch between different information sources and improving workflow efficiency.

AI summary
Provided is an ultrasound diagnostic apparatus to be applied to an ultrasound inspection of a living body part that moves with a movement of a subject in a living body inside the subject. The ultrasound diagnostic apparatus includes: an ultrasound image generation section that generates an ultrasound image based on a reception signal acquired from ultrasound probe which transmits and receives an ultrasound; an image analysis section that detects a movement of the subject by performing an image analysis of time-series camera images acquired from a camera which images the movement of the subject; and a display image generation section that generates a display image including the ultrasound image, and changes a display content or display mode of the display image in conjunction with the movement of the subject detected by the image analysis.
