Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The positioning of accessory units during magnetic resonance examinations often depends on the operator's experience, leading to potential issues with image quality, especially for inexperienced operators.
Innovation Solution
A method involving an acquisition unit to gather patient position data, a computing unit to determine the required position of accessory units, and a projection unit to guide the correct placement using characteristic patterns, facilitating precise and efficient positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning by medical operator is used, then positioning flexibility is maintained, but positioning precision deteriorates due to operator experience level
Solution Approach 1:
The patent introduces a computing unit as an intermediary between the operator and the positioning task. This unit receives patient data, determines the examination region, and calculates the optimal accessory unit position, thereby mediating the complex positioning task and enabling precise positioning without requiring operator expertise in anatomical positioning
Solution Approach 2:
The system enables self-service positioning by automatically determining the optimal position based on patient data and examination parameters. The accessory unit position is calculated autonomously by the computing unit using stored positioning data and patient-specific information, eliminating the need for operator judgment and experience
2Measurement precision
If automated positioning assistance is implemented, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The computing unit serves multiple functions: it stores positioning data for various patients and examination types, determines examination regions based on different criteria, calculates optimal accessory unit positions, and projects guidance patterns. This multi-functionality consolidates complex capabilities into a single integrated system component
Solution Approach 2:
The system performs preliminary actions by pre-storing positioning data for different patient types and examination regions. The computing unit uses this pre-prepared data to quickly determine optimal positions without requiring complex real-time calculations, thereby reducing the apparent system complexity during operation
