Solution Overview
Problem
Current systems for guiding instruments within the body face challenges in providing real-time, accurate visual feedback of instrument position and tissue type, especially when the instrument is moved quickly, leading to delayed or inaccurate tissue information display.
Innovation Solution
A guidance system that combines a medical imaging device with a tissue-type determination device operable in two accuracy modes, allowing for fast but less accurate tissue-type determination during instrument movement and higher accuracy when stationary, enabling simultaneous display of instrument position and tissue information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high accuracy tissue-type determination is performed continuously, then measurement precision is improved, but loss of time increases due to processing delays
Solution Approach 1:
The system dynamically adjusts the measurement accuracy based on the instrument's movement state. When the instrument is stationary or moving slowly, high accuracy measurement is performed. When the instrument moves quickly, the system switches to lower accuracy measurement mode, thereby adapting the measurement process to real-time operational conditions and resolving the contradiction between accuracy and time consumption.
Solution Approach 2:
The system changes the measurement parameters (accuracy level) based on the instrument speed. By monitoring the instrument's movement speed and adjusting the measurement accuracy parameter accordingly, the system optimizes the balance between obtaining accurate tissue-type information and minimizing processing time delays.
2Loss of time
If fast tissue-type determination is performed during instrument movement, then loss of time is reduced, but measurement precision deteriorates
Solution Approach 1:
The system dynamically adjusts the measurement accuracy based on the instrument's movement state. When the instrument is stationary or moving slowly, high accuracy measurement is performed. When the instrument moves quickly, the system switches to lower accuracy measurement mode, thereby adapting the measurement process to real-time operational conditions and resolving the contradiction between accuracy and time consumption.
Solution Approach 2:
The system changes the measurement parameters (accuracy level) based on the instrument speed. By monitoring the instrument's movement speed and adjusting the measurement accuracy parameter accordingly, the system optimizes the balance between obtaining accurate tissue-type information and minimizing processing time delays.
