3D Chest Contour Guidance for Coached Breathing During Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging systems face challenges in reducing patient movement during scans, particularly due to breathing, which degrades image quality, and existing coaching methods are costly, resource-intensive, or ineffective in real-time adjustments.
Innovation Solution
A method involving generating a 3-D virtual representation of a patient's chest or abdomen, displaying real-time breathing adjustments, and providing guidance to maintain a selected breathing pattern, with integrated LiDAR or 3-D camera technology to monitor and correct deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a technician provides personalized coached breathing instructions, then patient breathing control improves, but cost and preparation time increase
Solution Approach 1:
The system enables patients to perform self-coached breathing by displaying their real-time chest surface contour and allowing them to adjust their breathing to match target contours, eliminating the need for technician intervention while maintaining breathing control reliability
Solution Approach 2:
The system provides real-time visual feedback by displaying the patient's actual chest surface contour alongside target contours, enabling patients to self-correct their breathing patterns without requiring technician guidance, thus reducing preparation time while maintaining reliability
2Measurement precision
If optical or LiDAR imaging systems are added to generate 3-D visualization, then real-time breathing monitoring improves, but system cost and complexity increase
Solution Approach 1:
The medical imaging system performs dual functions by using its existing imaging capabilities to capture both medical image data and chest surface contour data, eliminating the need for separate optical or LiDAR imaging systems while maintaining measurement precision
Solution Approach 2:
The system merges medical imaging and surface contour acquisition into a single integrated process, using the same imaging hardware to serve both diagnostic and breathing monitoring purposes, thereby reducing system complexity while preserving measurement accuracy
3Reliability
If 3-D visualization is generated during the scan, then real-time breathing correction improves, but processing resources and memory increase
Solution Approach 1:
The system segments the imaging data processing by extracting only the relevant chest surface contour information from the full medical image data, processing only the necessary portion to maintain breathing patterns without requiring complete 3-D visualization, thus reducing processing resources while maintaining reliability

AI summary
Methods and systems are provided for aiding a subject of a medical imaging exam in performing coached breathing. In one embodiment, a method for a medical imaging system comprises generating a three-dimensional (3-D) virtual representation of a portion of a surface of a chest and/or abdomen of a subject of the medical imaging system, the portion adjustable in size by an operator of the medical imaging system; displaying changes in the 3-D virtual representation to the subject on a display device of the medical imaging system while the subject breathes, in real time; displaying instructions to the subject on the display device to perform coached breathing in accordance with a selected breathing pattern, using the 3-D virtual representation as a guide; and in response to detecting a deviation of a breathing pattern of the subject from the selected breathing pattern, indicating the deviation to the subject.
