X-ray Diagnosis Apparatus Dual Display Radiation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
X-ray diagnosis apparatuses face challenges in simultaneously displaying enlarged views of affected areas and wide-area images, with existing systems either limiting X-ray radiation to the affected area, preventing wide-area image acquisition, or requiring complex operations for frequent radiation range switching.
Innovation Solution
The apparatus incorporates a dual-display system with a control mechanism that allows parallel display of images from two radiation ranges, using a combination of high-resolution and low-resolution photodiode layers in the X-ray detector and a foot switch device for easy switching between narrow and wide radiation ranges, ensuring reduced subject exposure and intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If X-ray radiation is limited to only the affected area, then the subject receives a reduced dose of exposure, but images of the surrounding wide area cannot be acquired
Solution Approach 1:
The display system is segmented into multiple display areas (first display area for narrow-range images, second display area for wide-range images), allowing simultaneous presentation of both affected area details and surrounding context without requiring additional radiation exposure
Solution Approach 2:
The system stores and maintains display data from previous wide-range imaging before radiation range switching. When switching to narrow-range imaging, the stored wide-range display data is retained in the second display area, providing preliminary prepared information that eliminates the need for repeated wide-area radiation
2Measurement precision
If the display of enlarged affected-area view is selected, then the affected area is clearly visible, but the surrounding wide area context is lost
Solution Approach 1:
The system transitions from a single-dimensional display (either wide or narrow range) to a two-dimensional display layout where the first display area shows enlarged narrow-range images while the second display area simultaneously shows wide-range context, effectively adding a spatial dimension to the information presentation
Solution Approach 2:
The narrow-range display area is conceptually nested within the broader wide-range display area. The first display area (narrow range) can be viewed as a magnified portion of the second display area (wide range), creating a nested relationship where detailed view and context view coexist
3Adaptability or versatility
If frequent switching of radiation ranges is required for treatment, then the treatment can be adapted to different needs, but the operations become complex
Solution Approach 1:
The control interface is designed with universal control elements that can switch between narrow-range and wide-range radiation modes through a unified operation mechanism. The same control panel and switching logic serve multiple functions (radiation range switching, display area switching, image storage), reducing overall system complexity despite frequent mode changes
Solution Approach 2:
The system dynamically switches between different radiation ranges and display configurations based on real-time treatment needs. The control system automatically manages the transitions, storing and retrieving appropriate display data dynamically, allowing frequent adaptability without requiring complex manual operations for each switch

AI summary
According to one embodiment, an X-ray diagnosis apparatus includes an X-ray tube, a diaphragm mechanism, an X-ray detector, image generating circuitry, a display, a first interface, a second interface, and processing circuitry. The processing circuitry controls the diaphragm mechanism and the X-ray tube according to the operation to the first interface so that the X-rays are radiated to a first radiation range, and controls the diaphragm mechanism and the X-ray tube according to the operation to the second interface so that the X-rays are radiated to a second radiation range. The processing circuitry controls the display so that the first display area displays the X-ray images sequentially generated according to radiation of the X-rays, in parallel with the radiation.
