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, which affect image accuracy and quality.

Innovation Solution

The apparatus incorporates a 3D camera positioned on a tilted manner within a recessed guide groove of the X-ray generation part, allowing adjustment of focal distance and optical axis, and includes a driving control system to rotate the generator and sensor parts for enhanced imaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the camera is positioned in the direction of the sensor part, then the optical image can be acquired, but the camera is deteriorated by X-rays and the sensor part is excessively enlarged

Engineering Contradiction:
Improveoptical image acquisition accuracyVSAvoidcamera durability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The camera is repositioned from the traditional direction (facing the sensor part) to a new dimension - positioned on the generator part and tilted at a predetermined angle. This spatial reconfiguration allows the camera to acquire optical images of the patient's face without being in the direct path of X-rays, thereby preventing deterioration while maintaining imaging capability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The generator part serves as an intermediary structure that holds the camera at a tilted angle. This intermediary positioning structure enables the camera to be shielded from direct X-ray exposure while still capturing the required optical images, resolving the conflict between image acquisition and camera protection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

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

Engineering Contradiction:
Improve3D optical imaging capabilityVSAvoidsensor part size
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The system is segmented into functionally independent components: the X-ray generation function remains in the generator part, while the 3D optical imaging function is separated and positioned on the generator part as well, but in a different location (on the side, tilted). This segmentation allows each component to perform its function without requiring excessive space, avoiding the need to enlarge the sensor part

Inventive Principle:
Principle #1Segmentation

3Area of stationary object

If the camera is positioned to capture wide field of view, then more comprehensive optical images are acquired, but the camera becomes vulnerable to X-ray exposure

Engineering Contradiction:
Improvefield of view coverageVSAvoidX-ray exposure to camera
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The camera is positioned in another dimension - on the generator part and tilted at a predetermined angle - which allows it to capture a wide field of view of the patient's face while being naturally shielded from direct X-ray exposure by the angular arrangement, thus achieving both comprehensive imaging and protection

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.
