X-ray Generator 3D Posture Tracking for Retake Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray generators and detectors are difficult to position accurately for retaking images in the same position and direction, especially when miniaturized and portable, making it challenging to ensure identical setup for repeat X-ray imaging.
Innovation Solution
An X-ray generation and detection system that includes a 3D posture information detector and communicator to track and transmit the position and direction of both the X-ray generator and detector, allowing for comparison and adjustment to match previous image-taking positions and directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If X-ray generators and detectors are miniaturized and made portable, then ease of operation and mobility are improved, but the ability to accurately identify and maintain relative positional relationships between generator and detector deteriorates
Solution Approach 1:
The patent introduces a marker as an intermediary element attached to either the X-ray generator or detector. This marker serves as a reference object that enables the user to visually identify and maintain the correct relative positional relationship between the generator and detector during retake operations, solving the positioning difficulty inherent in portable miniaturized systems
2Manufacturing precision
If X-ray generators and detectors are made much larger than the subject, then manufacturing precision and stability are improved, but ease of operation and mobility deteriorate
Solution Approach 1:
The patent segments the X-ray system into separate portable generator and detector units that can be independently positioned. By dividing the system rather than using a single large integrated unit, the patent achieves both portability and positioning stability through the use of markers and visual alignment methods
3Ease of operation
If users hold X-ray generator or detector for themselves, then ease of operation is improved, but the ability to identify relative positional relationship between generator and detector deteriorates
Solution Approach 1:
The patent uses visual markers with distinct characteristics (analogous to color changes in TRIZ) that provide clear visual feedback to the user. The markers enable users to easily perceive and maintain the correct spatial relationship between generator and detector without requiring complex electronic displays or instructions

AI summary
An X-ray generation system and an X-ray detection system can be used in a method for taking X-ray images. The X-ray generation system includes an X-ray generator that generates X-rays and emits the generated X-rays to an external device. A three-dimensional (3D) posture information detector generates 3D posture information for the X-ray generator, and a communicator transmits the 3D posture information to the external device.
