Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging systems for coronary artery disease diagnosis and treatment lack accurate synchronization between intravascular sensors and imaging devices, leading to reduced precision and increased complexity due to the need for additional navigation devices.
Innovation Solution
A method and system that simultaneously acquires data from an intravascular sensor and images of the vascular system, registering the sensor's location relative to the data collected, allowing for precise display and positioning on a reference image without requiring additional navigation devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If practitioner knowledge is used to register sensor information on reference images, then diagnostic accuracy can be achieved, but the practitioner becomes engaged in manual registration tasks during the medical procedure
Solution Approach 1:
The system performs automatic registration of sensor information on reference images using image processing algorithms and computer vision techniques, eliminating the need for manual practitioner intervention. The system independently identifies anatomical landmarks and aligns the sensor data with the reference image through automated computational methods.
Solution Approach 2:
The manual mechanical registration process performed by practitioners is replaced with an automated computational system that uses image processing, pattern recognition, and algorithmic methods to achieve registration, substituting human manual operations with automated technological systems.
2Measurement precision
If additional navigation devices are used to track sensor location in 3D space, then registration precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and removes the need for separate additional navigation devices by integrating sensor tracking capabilities directly into the existing imaging system. The sensor location is determined through image processing of the acquired images rather than requiring independent navigation hardware.
Solution Approach 2:
The imaging system is designed to perform multiple functions: acquiring medical images, tracking sensor location, and registering sensor information on reference images. This multi-functional approach eliminates the need for dedicated navigation devices, as the imaging system itself provides all necessary capabilities.
3Measurement precision
If synchronous acquisition of sensor data and images is implemented, then registration accuracy is improved, but data processing complexity increases
Solution Approach 1:
The acquisition of sensor data and image data is merged into a single synchronized process. Both types of data are collected simultaneously during the same imaging procedure, ensuring that the sensor information and image information correspond to the same spatial and temporal moment, which simplifies the registration process.

AI summary
A system and method of processing images of a region of interest of a patient is provided. The method comprises acquiring a reference image of the region of interest of the patient; during a pullback of an intravascular sensor in the region of interest, triggering simultaneously the steps of: acquiring a data collected by the sensor characteristic of the region of interest; and acquiring a succession of images of the region of interest associated with the location of the intravascular sensor when acquiring the data, respectively. The method further includes registering the succession of images; associating the location of the intravascular sensor relative to the step of acquiring the data collected by the intravascular sensor; and displaying and positioning the data collected by the intravascular sensor on the reference image in correspondence to the location of the intravascular sensor at the respective step of acquiring the data.
