Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional x-ray CT imaging apparatuses require manual adjustments to change the imaging object region display for different imaging modes, which is cumbersome and time-consuming, especially when switching between various x-ray CT imaging modes with different radiation fields.
Innovation Solution
An x-ray CT imaging apparatus that includes an x-ray generator, an x-ray image sensor, an imaging mode selection part, an image generation part, an operation part, a moving mechanism, and a display part, which allows for automatic adjustment of the imaging object region display based on the selected x-ray CT imaging mode, enabling easy positioning and reducing the need for manual mode selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to change the imaging object region display for different imaging modes, then the system maintains simplicity in configuration, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system pre-stores multiple imaging object region displays corresponding to different x-ray CT imaging modes in advance. When a mode is selected, the corresponding display is automatically retrieved and displayed without requiring manual adjustment, thus resolving the contradiction between operational ease and time consumption.
2Productivity
If the imaging object region display is automatically changed according to the selected imaging mode, then the productivity is improved, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The display unit serves multiple functions: it displays the position setting image, superimposes the imaging object region display, and automatically switches between different displays based on the selected imaging mode. This multi-functionality approach improves productivity without significantly increasing device complexity, as the same hardware components perform multiple tasks.
3Adaptability or versatility
If multiple imaging modes with different radiation fields are supported, then the adaptability is improved, but the ease of operation deteriorates due to the need to manually adjust displays for each mode
Solution Approach 1:
The system changes the display parameters (imaging object region display) automatically based on the selected imaging mode. By linking the display parameters to the mode selection, the system maintains ease of operation while supporting multiple imaging modes with different radiation fields, thus resolving the contradiction between adaptability and ease of operation.

AI summary
An x-ray CT imaging apparatus emits an x-ray cone beam to an object to generate an x-ray CT image on the basis of a transmission x-ray which is transmitted through the object. An image generation part generates an image obtained by superposing an imaging object region display on a position setting image representing the object and displays the image on a display part. The image generation part changes the imaging object region display in accordance with an x-ray CT imaging mode selected by an imaging mode selection part.
