X-Ray Imaging Condition Setting Using Virtual Medical Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical imaging, particularly X-ray imaging, inappropriate imaging conditions set by users with varying experience can lead to undesired medical images or unnecessary X-ray exposure due to the need for re-imaging, and existing methods relying on standard human body models may fail for objects deviating from these standards.
Innovation Solution
An information processing apparatus that utilizes a generative model to generate virtual medical images based on camera images, allowing for the setting of precise imaging conditions, including angle, position, and range of the X-ray tube, to achieve desired medical images without requiring objects to change posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If imaging conditions are set based on standard human body models, then imaging can be performed efficiently, but imaging accuracy deteriorates for objects deviating from standard postures
Solution Approach 1:
The system performs preliminary actions by capturing a camera image of the object's actual posture before imaging, then uses this information to generate a virtual medical image and determine appropriate imaging conditions. This preliminary capture and virtual imaging step allows the system to adapt to non-standard postures while maintaining imaging efficiency.
Solution Approach 2:
The system changes imaging parameters (angle, position, range of X-ray tube) based on the virtual medical image generated from the camera image. By adjusting these parameters according to the actual object posture captured in the camera image, the system achieves accurate imaging for objects deviating from standard postures.
2Loss of time
If inappropriate imaging conditions are used, then imaging can be performed quickly, but unnecessary X-ray exposure occurs due to re-imaging
Solution Approach 1:
The system performs preliminary determination of imaging conditions by generating a virtual medical image from a camera image before actual imaging. This preliminary step identifies the appropriate imaging conditions in advance, preventing the need for re-imaging and thus avoiding unnecessary X-ray exposure while maintaining quick imaging.
Solution Approach 2:
The system uses feedback from the camera image and virtual medical image to determine and adjust imaging conditions. This feedback mechanism ensures that imaging conditions are optimized based on the actual object posture, preventing unnecessary re-imaging and reducing X-ray exposure.
3Adaptability or versatility
If user experience varies, then operation flexibility increases, but imaging quality deteriorates due to inconsistent condition setting
Solution Approach 1:
The system performs self-service by automatically determining imaging conditions based on the camera image and virtual medical image, without requiring user expertise. The system independently analyzes the object posture and generates appropriate imaging conditions, ensuring consistent imaging quality regardless of user experience while maintaining operation flexibility.
Solution Approach 2:
The system replaces the mechanical process of manual condition setting by users with an automated image processing system. By substituting human expertise with an automated system that uses camera images and virtual medical images to determine imaging conditions, the system ensures consistent imaging quality while maintaining operational flexibility.
