Solution Overview
Problem
Motion artifacts in medical imaging due to patient or table movement lead to misdiagnosis, increased resource wastage, and health risks from repeated scans, necessitating improved motion management techniques.
Innovation Solution
A system and method for motion-gated medical imaging using sensor devices and logic to detect and manage motion, allowing for real-time adjustment of scan parameters, medication administration, and image processing to minimize motion artifacts and reduce the need for sedation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sedation is administered to address patient motion during scanning, then motion artifacts are reduced, but medical risk and workflow complexity increase
Solution Approach 1:
A motion detection device is introduced as an intermediary between the patient and the imaging system. The device detects patient motion and generates control signals that automatically adjust scanning parameters or trigger re-scanning, eliminating the need for sedation while maintaining image quality.
Solution Approach 2:
The system implements a feedback loop where motion detection continuously monitors patient position, and the imaging system automatically adjusts its operation in response to detected motion. This real-time feedback enables motion compensation without pharmacological intervention.
2Manufacturing precision
If re-scanning is conducted to address motion artifacts, then diagnostic accuracy is improved, but resource wastage and exposure risk increase
Solution Approach 1:
Motion detection operates continuously before, during, and after scanning to predict and prevent motion artifacts. By detecting motion in advance or immediately, the system can trigger targeted re-scanning of only affected regions rather than performing complete re-scans, conserving resources and reducing exposure.
Solution Approach 2:
The imaging volume is divided into multiple segments or regions of interest. When motion is detected, only the specific segment affected by motion is re-scanned rather than the entire scan range, reducing resource consumption and patient exposure while maintaining overall diagnostic accuracy.
3Reliability
If motion detection is performed across the entire data capture range, then all motion is detected, but processing time and complexity increase
Solution Approach 1:
Motion detection is focused on specific regions of interest within the data capture range rather than uniformly across the entire field. The system identifies anatomical regions most susceptible to motion artifacts and concentrates detection resources there, reducing processing complexity while maintaining detection reliability.

AI summary
Systems, apparatuses, and/or methods to provide motion-gated medical imaging. An apparatus may identify a data capture range of a sensor device that is to capture motion of an object during a scan process by a medical imaging device. An apparatus may identify a prescribed scan range. An apparatus may focus motion detection to a region of interest in the data capture range based on the prescribed scan range.
