Solution Overview
Problem
Current technologies face challenges in precisely monitoring the relative location and motion between objects, especially in medical procedures where uncontrolled sample motion and low contrast in anatomical structures hinder accurate imaging and scanning.
Innovation Solution
The use of acoustic or electromagnetic radiation is employed to determine the relative distance and velocity between objects, with a medical catheter configured to emit and detect radiation, processing signals to correct for motion and maintain precise scan patterns, especially in three-dimensional coronary artery microscopy procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional imaging technologies are used to monitor relative location and motion, then the system is simple to operate, but the measurement precision is insufficient due to low contrast in anatomical structures
Solution Approach 1:
The patent applies contrast agents that alter the acoustic or electromagnetic properties of anatomical structures, making them detectable by the imaging system. The contrast agent changes the acoustic impedance or electromagnetic characteristics of the target structure, enabling precise monitoring of relative location and motion that would otherwise be impossible due to low natural contrast.
Solution Approach 2:
The patent introduces an intermediary contrast agent between the imaging system and the anatomical structure. This intermediary substance enhances the interaction between the imaging modality and the target structure, allowing for accurate detection of relative position and motion without requiring complex modifications to the imaging system itself.
2Measurement precision
If the imaging system operates without motion compensation, then the device complexity is low, but the measurement precision deteriorates due to uncontrolled sample motion
Solution Approach 1:
The patent implements a feedback mechanism where the imaging system continuously monitors the position of both the catheter and anatomical structures, compares actual positions with desired positions, and adjusts the scan pattern in real-time to compensate for motion. This closed-loop control maintains measurement precision despite the added complexity of motion tracking.
Solution Approach 2:
The patent makes the imaging system dynamic by enabling real-time adaptation of the scan pattern based on detected motion. The system transitions from a static predetermined scan pattern to a dynamic compensatory scan pattern that adjusts continuously to maintain precision during physiological motion.
3Manufacturing precision
If a predetermined scan pattern is used without motion compensation, then the ease of operation is high, but the manufacturing precision of the scan pattern is compromised by uncontrolled motion
Solution Approach 1:
The system uses feedback from motion sensors and imaging data to automatically adjust the scan pattern in real-time, maintaining fidelity without requiring manual intervention. The computer-controlled system handles the complexity of motion compensation automatically, preserving ease of operation while achieving high scan pattern precision.
Solution Approach 2:
The patent replaces manual mechanical scan control with computer-controlled adaptive scanning. The system uses software algorithms to calculate and apply scan pattern corrections based on detected motion, substituting complex mechanical adjustment mechanisms with intelligent control systems that maintain precision while keeping the interface simple.
