Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical image display systems lack the ability to accurately and automatically mark and record biopsy positions relative to a reference point, making it difficult to compare and track biopsy locations over time, especially when using different imaging modalities like ultrasound, MR, and CT.
Innovation Solution
A medical image display apparatus and method that utilizes a processor to obtain information from sensors attached to probes and needles to determine and mark tissue extraction positions in real-time, allowing for the matching of needle positions with medical image data, including ultrasound, MR, and CT images, and storing this information for comparison across different biopsy sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual marking of biopsy positions is used, then device complexity is reduced, but measurement precision and productivity deteriorate
Solution Approach 1:
The system performs automatic biopsy position marking using sensors attached to the probe and needle, combined with image processing algorithms. The apparatus self-determines the tissue extraction position by integrating sensor data with medical images, eliminating the need for manual marking while improving precision and efficiency
2Measurement precision
If multiple imaging modalities are integrated, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system is designed to handle multiple imaging modalities (ultrasound, MR, CT) through a unified platform. The processor can process different types of medical image data and sensor information, making the apparatus versatile for various biopsy scenarios while maintaining consistent precision through standardized processing algorithms
3Productivity
If automatic position determination is implemented, then productivity improves, but device complexity increases
Solution Approach 1:
The system replaces manual mechanical marking operations with automated sensor-based detection and image processing. Sensors attached to the probe and needle automatically track position, and algorithms process the data to determine biopsy locations, substituting manual operations with automated electronic systems that improve efficiency
4Measurement precision
If real-time position tracking is implemented, then measurement precision improves, but use of energy increases
Solution Approach 1:
The system performs position determination at critical moments during the biopsy procedure rather than continuous tracking. The processor determines the tissue extraction position based on sensor data obtained during key phases of needle insertion and tissue sampling, reducing energy consumption while maintaining measurement precision when needed
