Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging technologies for heart function evaluation, such as MRI and CT, are costly and burdensome for patients, and require multiple imaging operations, which is not feasible for small medical institutions.
Innovation Solution
A dynamic radiographing system that uses a plain X-ray radiographing device to generate X-ray images of the heart in multiple time phases, analyzing these images to calculate evaluation values for heart function, including blood speed, cardiac output, and movement, using a radiographing device with an X-ray source and detector, image analysis device, display device, and control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MRI or CT radiographing apparatuses are used for heart function evaluation, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses plain X-ray radiography to create a simplified copy of the imaging process, capturing heart movement information through sequential images rather than requiring complex MRI or CT apparatuses. The X-ray system captures multiple time-phase images that are then processed to extract heart function data, providing a cost-effective alternative that maintains essential measurement capabilities
Solution Approach 2:
The patent replaces complex mechanical imaging systems (MRI/CT) with a simpler X-ray system combined with image processing. Instead of using expensive magnetic resonance or computed tomography hardware, the system uses affordable plain X-ray radiography with subsequent digital image analysis to achieve heart function evaluation
2Measurement precision
If multiple imaging operations are performed using different apparatuses, then measurement precision is improved, but loss of time and patient burden increase
Solution Approach 1:
The patent merges multiple imaging functions into a single plain X-ray radiography system. By capturing multiple time-phase images sequentially with one apparatus, it eliminates the need to switch between different imaging devices (ultrasound, MRI, CT), thereby reducing examination time and patient burden while still obtaining comprehensive heart function data
Solution Approach 2:
The plain X-ray radiography system is made multi-functional by using it for both basic radiography and dynamic heart function evaluation. The same apparatus performs multiple imaging operations by adjusting timing and processing parameters, rather than requiring separate specialized devices for each function
3Measurement precision
If catheter examination is performed, then measurement precision is improved, but object-affected harmful factors increase
Solution Approach 1:
The patent creates a non-invasive copy of the measurement approach by using external X-ray imaging instead of internal catheter insertion. The system captures heart function data from the outside through sequential X-ray images, eliminating the need for invasive procedures while maintaining the ability to evaluate heart movement and function

AI summary
A dynamic radiographing system enables determination of an evaluation value of the heart function of a subject by plain radiography. The dynamic radiographing system comprises a radiographing apparatus, an image processing apparatus, and a console for diagnosis. The radiographing apparatus dynamically radiographs the heart of a subject and creates radiographs in plural time phases (Step S1). The image processing apparatus calculates an evaluation value of the heart function by using the radiographs in plural time phases (Step S4). The console for diagnosis displays information on the calculated evaluation value on the display section (Step S5).
