Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MRI systems require skilled technicians for complex and time-consuming diagnostic examinations, especially in dental applications, due to the need for meticulous preparation and manual target volume definition.
Innovation Solution
A dental MRI system that provides field-of-view information based on a region of interest, allowing for automatic selection of diagnostic applications and recording sequences, enabling technicians without extensive training to perform examinations by positioning imaging coils and generating diagnostic images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual preparation and target volume definition are performed by skilled technicians, then diagnostic image quality is optimized, but examination time is extended and operational complexity increases
Solution Approach 1:
The system automatically performs target volume definition and recording sequence selection based on pre-stored diagnostic information, enabling the MRI system to serve itself without requiring skilled technicians to manually define volumes or select sequences, thus reducing examination time while maintaining diagnostic quality
Solution Approach 2:
Diagnostic information including target volume definitions and recording sequences are pre-stored in the system memory before the actual examination. During the exam, the system automatically retrieves and applies this pre-prepared information, eliminating the need for real-time manual preparation and reducing examination time
2Measurement precision
If manual definition of recording sequences is performed, then diagnostic accuracy is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The MRI system automatically selects and configures appropriate recording sequences based on pre-stored diagnostic information related to the specific diagnostic inquiry, eliminating the need for technicians to manually define complex sequence parameters and reducing operational difficulty
Solution Approach 2:
The system stores multiple pre-configured recording sequences and diagnostic protocols in memory that can be automatically selected based on the type of diagnostic inquiry, making the system universally applicable to various dental examinations without requiring manual reconfiguration for each case
3Measurement precision
If skilled technicians perform meticulous preparation, then image quality is optimized, but ease of operation deteriorates
Solution Approach 1:
The system automatically performs all preparation steps including target volume definition, coil position verification, and recording sequence selection based on pre-stored diagnostic information, eliminating the need for skilled technicians to perform meticulous manual preparation while maintaining image quality
Solution Approach 2:
The manual mechanical process of technician-operated preparation and parameter adjustment is replaced by an automated computer-controlled system that retrieves pre-stored diagnostic information and automatically configures the examination parameters, thereby improving ease of operation
