Radiography Apparatus Confirmation Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiography apparatuses face challenges in generating confirmation images quickly while ensuring the quality of diagnosis images, as the process related to image quality increases the time required for generating confirmation images.
Innovation Solution
A radiography apparatus comprising a radiation source, a radiation detector with an imaging sensor unit having overlapping imaging sensors, and a processor that acquires radiographic images, performs image quality processes for diagnosis images, but does not perform these processes for confirmation images, thereby reducing the generation time of confirmation images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image quality processes are performed on confirmation images, then the quality of the confirmation image is improved, but the time required to generate the confirmation image increases
Solution Approach 1:
The patent applies different processing standards to different types of images: diagnosis images receive full image quality processes while confirmation images use simplified processing. This local differentiation of quality requirements resolves the contradiction by ensuring high quality where needed (diagnosis) while minimizing processing time where quality requirements are lower (confirmation).
Solution Approach 2:
For confirmation images, the patent implements partial image quality processing - performing only essential processing steps rather than complete processing. This partial action approach maintains sufficient quality for confirmation purposes while significantly reducing processing time compared to full processing.
2Manufacturing precision
If image quality processes are performed on all images, then the quality of diagnosis images is maintained, but the overall imaging time increases
Solution Approach 1:
The patent implements a differentiated processing strategy where diagnosis images receive complete image quality processes to ensure high quality for medical diagnosis, while confirmation images receive simplified processing. This local quality approach ensures that the critical diagnosis images maintain high quality standards while the non-critical confirmation images are processed faster, thereby resolving the contradiction between quality and productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the rapid generation of confirmation images while maintaining the quality of diagnosis images, thereby reducing the overall imaging time.
Implementation Method 1
a radiation detector having an imaging sensor unit which includes at least two imaging sensors of a first imaging sensor and a second imaging sensor that have a rectangular plate shape and include pixels that sense the radiation or visible light converted from the radiation and generate charge
Data Source
AI summary
A radiation detector has a sensor panel unit which includes two sensor panels and in which end portions of the two sensor panels are arranged to overlap each other in a thickness direction. An image processing unit acquires two projection images from the two sensor panels. A combination unit of the image processing unit performs a process related to image quality on the projection image in a case in which a tomographic image which is a diagnosis image to be used for a doctor's diagnosis is generated and does not perform the process related to image quality on the projection image in a case in which a scout image which is a confirmation image for confirming a reflected state of the subject is generated.
