Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging apparatuses face issues such as camera deterioration due to X-rays, excessive sensor size, and limited field of view, particularly in extraoral setups.
Innovation Solution
An X-ray imaging apparatus with a rotating generator and sensor setup, incorporating a 3D camera disposed within a guide groove of the generator part, allowing for adjusted focal distance and optical axis, and a camera part that is protected from X-rays by being positioned on the X-ray generation part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is positioned in the direction of the sensor part, then the camera can capture optical images, but the camera is deteriorated by X-rays and the sensor part becomes excessively enlarged
Solution Approach 1:
The camera is repositioned from the traditional direction (facing the sensor part) to a different spatial dimension (disposed on the side surface of the generator part). This dimensional change allows the camera to capture optical images of the subject while being physically separated from the X-ray path, thereby preventing X-ray deterioration while maintaining imaging capability
Solution Approach 2:
The side surface of the generator part serves as an intermediary mounting position that mediates between the camera's need to capture images and the requirement to protect it from X-rays. By placing the camera on this intermediary surface rather than directly in the X-ray path, both imaging function and protection are achieved
2Measurement precision
If a camera is mounted on the generator part, then 3D optical images can be acquired, but the focal distance and optical axis adjustment becomes complex
Solution Approach 1:
The camera is designed with adjustable focal distance and optical axis capabilities, allowing dynamic adaptation to different imaging requirements. This dynamic adjustability enables accurate 3D optical image acquisition while maintaining operational flexibility despite the complex positioning on the side surface of the generator part
3Measurement precision
If the sensor part is enlarged to accommodate a 3D camera, then 3D optical imaging is enabled, but the sensor part becomes excessively large in size
Solution Approach 1:
The imaging system is segmented into separate functional components: the X-ray generation function remains in the generator part, while the optical imaging function is separated and mounted on the side surface of the generator part. This segmentation allows the sensor part to maintain its original size while the camera, positioned independently on the side surface, provides 3D optical imaging capability without requiring enlargement of the sensor part

AI summary
Proposed is an X-ray imaging apparatus comprising an imaging part comprising a generator part and a sensor part facing each other with an imaging subject positioned therebetween and a driving control part configured to rotate the generator part and the sensor part around a rotation axis positioned between the generator part and the sensor part, thereby radiographing an X-ray image of the imaging subject. The generator part comprises an X-ray generation part configured to generate X-rays emitted toward the imaging subject by being controlled by the driving control part and a camera part configured to photograph a three-dimensional (3D) optical image of the imaging subject by being controlled by the driving control part when the generator part and the sensor part are rotated, wherein the camera part is disposed within a guide groove recessed from an outer surface of the generator part to an inner portion of the generator part and the X-ray generation part is disposed on a first side of the guide groove.
