Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current X-ray image diagnosis systems face challenges in effectively controlling the capturing direction during trans-catheter aortic valve replacement (TAVR) procedures to minimize overlap between reverse blood flow components and prosthetic valves, making it difficult to accurately evaluate abnormal blood flow.
Innovation Solution
An X-ray image diagnosis apparatus with a fluid information acquisition unit, registration unit, and capturing direction controller that acquires blood flow information, registers the position and orientation of ultrasound and angiography images, and adjusts the capturing direction of the angiography apparatus to minimize overlap between reverse flow components and prosthetic valves, allowing for real-time fusion imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the capturing direction is not controlled, then the imaging process is simple and quick, but the overlap between reverse flow components and prosthetic valves occurs making accurate evaluation difficult
Solution Approach 1:
The system acquires fluid information (blood flow direction) from the target site, uses this feedback to determine the optimal capturing direction, and adjusts the capturing direction accordingly. This closed-loop feedback mechanism ensures that the capturing direction is continuously optimized to minimize overlap between reverse flow components and prosthetic valves, thereby improving evaluation accuracy without requiring complex manual intervention.
Solution Approach 2:
The system automatically determines the capturing direction based on the acquired fluid information without requiring external manual input. The capturing direction controller self-adjusts the imaging parameters and direction based on the blood flow characteristics, enabling the system to serve itself in optimizing the imaging configuration for minimal overlap.
2Loss of information
If real-time fusion imaging is implemented, then the visualization of blood flow and anatomical structures is improved, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary actions by acquiring fluid information and determining the optimal capturing direction before the actual fusion imaging process. By pre-processing and pre-planning the imaging parameters based on blood flow characteristics, the system reduces the computational burden during real-time fusion imaging, thereby maintaining information completeness while minimizing processing time delays.

AI summary
An X-ray image diagnosis apparatus includes an X-ray tube, an X-ray detector, a fluid information acquisition unit, a registration unit, and a capturing direction controller. The X-ray tube emits X-rays toward a subject. The X-ray detector detects the X-rays having passed through the subject. The fluid information acquisition unit acquires fluid information on a target site including a region of interest of the subject captured by an ultrasound image diagnosis apparatus. The registration unit extracts position information of a probe of the ultrasound image diagnosis apparatus. The capturing direction controller controls capturing direction for capturing the target site based on the position information and a direction in which a fluid flows indicated by the fluid information.
