Solution Overview
Problem
Medical imaging requires accurate and repeatable patient positioning for diagnostic scanning, which is often time-consuming and prone to inaccuracy due to manual operations.
Innovation Solution
A system and method that acquires image data of a patient, determines position information using trained models, and automatically adjusts the scanning table and scanner parameters to facilitate precise imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning and parameter setting are used, then operator control and flexibility are maintained, but time consumption increases and positioning accuracy decreases
Solution Approach 1:
The system enables automated positioning by having the scanning table and imaging device self-adjust based on processed image data and determined position information, eliminating the need for manual operator intervention in positioning and parameter setting tasks
Solution Approach 2:
The patent replaces manual mechanical positioning operations with an automated control system that processes image data, determines position information using trained models, and automatically adjusts the scanning table and imaging device parameters
2Reliability
If manual operations are used for table positioning and parameter setting, then system complexity remains low, but positioning repeatability and diagnostic accuracy deteriorate
Solution Approach 1:
The system acquires image data, processes it through trained models to determine position information, and uses this feedback to automatically adjust the scanning table and imaging device parameters, creating a closed-loop control system that ensures repeatable and accurate positioning
Solution Approach 2:
The system performs preliminary image acquisition and processing to determine position information before the actual scanning operation, allowing the scanning parameters and table position to be pre-configured for optimal diagnostic imaging
3Productivity
If automated imaging is implemented, then productivity and accuracy improve, but device complexity and initial time investment increase
Solution Approach 1:
The imaging system integrates multiple functions including image acquisition, image processing, position determination using trained models, and automatic control of scanning table and parameters into a single unified system, improving productivity while managing complexity through functional integration
