Solution Overview
Problem
Conventional X-ray imaging apparatuses face challenges in accurately superimposing exterior images onto X-ray images, requiring extensive image adjustment procedures and patient movement for simultaneous acquisition.
Innovation Solution
An X-ray imaging apparatus equipped with a removably mounted three-dimensional scanner that allows for simultaneous or alternative acquisition of X-ray and exterior images, minimizing adjustment procedures and enabling stationary patient imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional X-ray imaging apparatus is used to acquire both X-ray images and exterior images, then diagnostic data can be obtained, but extensive image adjustment procedures are required and patient movement is needed for simultaneous acquisition
Solution Approach 1:
The patent combines the exterior image acquisition device (scanner) with the X-ray imaging apparatus into an integrated system. The scanner is mounted on the X-ray imager body, allowing both imaging functions to be performed simultaneously on the same patient without requiring separate imaging sessions or extensive image adjustment procedures for superimposition.
Solution Approach 2:
The patent introduces a positioning mechanism as an intermediary component that includes a positioning table and positioning means. This positioning system accurately locates the patient's head position and maintains it during both exterior image scanning and X-ray imaging, eliminating the need for manual image adjustment and achieving precise superimposition.
2Measurement precision
If separate imaging sessions are conducted for X-ray and exterior images, then each image type can be acquired, but patient movement occurs and superimposition accuracy decreases
Solution Approach 1:
The patent merges the exterior image scanner and X-ray imager into a single integrated system that can acquire both types of images simultaneously. The scanner and X-ray beam generator are coordinated to image the same patient position at the same time, eliminating patient movement between sessions and ensuring accurate superimposition.
Solution Approach 2:
The patent employs preliminary positioning actions where the patient's head is positioned on the positioning table and secured before imaging begins. The positioning means pre-establishes the correct spatial relationship between the patient, scanner, and X-ray beam, ensuring that both images are acquired from the same reference position.
3Measurement precision
If the scanner is permanently integrated with the X-ray imager, then superimposition accuracy improves, but device versatility and reusability decrease
Solution Approach 1:
The patent segments the imaging system into separable components: the scanner body is detachably mounted on the X-ray imager body through a coupler mechanism. This allows the scanner to be removed and used with different X-ray imagers or for other purposes, while maintaining precise superimposition accuracy when mounted on a specific imager through the positioning mechanism.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the accuracy of superimposition between X-ray and exterior images, reduces patient inconvenience, and improves usability by allowing the scanner to be detached and reused or mounted on different X-ray imagers.

AI summary
The present invention relates to an X-ray imaging apparatus, comprising: an X-ray imager including an X-ray beam generator for emitting an X-ray beam, an X-ray beam detector for detecting the X-ray beam to obtain an X-ray image of an object, and a main body unit in which the X-ray beam generator and the X-ray beam detector are installed; and a three-dimensional scanner arranged in the X-ray imager in order to obtain an image of the outer appearance of the object. According to the present invention, an X-ray image and an image of the outer appearance of an object, for example, an image of the skull and an image of the face, can be obtained at the same time, thereby minimizing image correction procedures for matching two images.
