X-ray Dose Reduction via Viewer Parameter Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical X-ray devices often use excessive X-ray doses during imaging, which can compromise image quality due to ambient conditions and viewing parameters, leading to unnecessary high doses being selected for recording.
Innovation Solution
A method that determines viewer-specific parameters such as viewing distance, ambient brightness, and reflections to adjust the X-ray dose and image recording settings, including resolution, edge enhancement, and contrast, to optimize image quality based on the maximum displayable measure, thereby reducing the X-ray dose required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a high X-ray dose is used during imaging, then image quality is improved, but the X-ray dose to the patient increases unnecessarily
Solution Approach 1:
The system dynamically changes recording parameters including X-ray dose, resolution, and contrast based on determined viewing parameters such as viewing distance and ambient brightness. This allows optimization of image quality to match actual viewing conditions, avoiding unnecessary high doses when lower quality suffices for the given display scenario
Solution Approach 2:
The system performs preliminary determination of viewing parameters (viewing distance, ambient brightness, reflections) before image acquisition. Based on this preliminary information, the optimal recording parameter set including X-ray dose is pre-calculated and selected, ensuring that the patient receives the minimum necessary dose for the required image quality under specific viewing conditions
2Object-affected harmful factors
If the X-ray dose is reduced, then patient safety is improved, but image quality may be degraded
Solution Approach 1:
The system adjusts multiple recording parameters simultaneously (X-ray dose, resolution, contrast, edge enhancement) based on viewing conditions. This multi-parameter optimization ensures that image quality remains adequate for the specific viewing scenario even when X-ray dose is reduced, as other parameters compensate to maintain perceived quality
Solution Approach 2:
The system dynamically adapts recording parameters to match the specific viewing situation rather than using fixed parameters. By making the parameter selection dynamic and context-dependent, the system achieves adequate image quality at lower doses by matching the recording quality to the actual viewing requirements
3Manufacturing precision
If high resolution recording is used, then image detail is improved, but X-ray dose increases
Solution Approach 1:
The system changes the resolution parameter dynamically based on viewing distance and display size. When viewing distance is large or display size is small, lower resolution is selected, reducing the required X-ray dose. When viewing conditions require finer detail, higher resolution is selected, optimizing the balance between image quality and radiation exposure

AI summary
The disclosure relates to a method for imaging by a medical X-ray device. In order to enable a reduction of an X-ray dose during imaging, the method includes: determining a viewing parameter of a viewer with reference to a future display of an image recorded by the X-ray device, determining a recording parameter set including an X-ray dose at least partially in dependence on the viewing parameter, and recording an image by the X-ray device using the recording parameter set.
