Optical Camera Angle Adjustment for Radiographic Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging systems face inconvenience in checking and analyzing optical images due to changes in radiographic imaging conditions, such as Source to Image receptor Distance (SID) and radiation detector size, which affect the area and direction imaged, leading to improper fitting of subjects in optical images.
Innovation Solution
A radiographic imaging system comprising a radiographic imager, an optical imager, and an optical imaging condition setter that adjusts the optical imaging conditions based on radiographic imaging conditions, including setting the angle of view and direction of the optical camera to maintain a consistent imaging area and direction regardless of SID, imaging part, and radiation detector size.

Engineering Contradiction Analysis
1Device complexity
If the angle of view of an optical camera remains unchanged when SID is changed, then the camera structure is simple, but the area of subject to be imaged changes and the subject may not fit in the optical image
Solution Approach 1:
The optical camera's angle of view is made dynamically adjustable based on radiographic imaging conditions. When SID changes, the camera automatically adjusts its angle of view to maintain consistent subject framing, transforming from a static to a dynamic system that adapts to varying imaging parameters.
Solution Approach 2:
The camera's imaging parameters (angle of view) are changed in response to changes in radiographic parameters (SID). This parameter coupling ensures that as SID varies, the camera adjusts its field of view accordingly to keep the subject properly framed in the optical image.
2Adaptability or versatility
If the optical camera is integrated with the radiation source near the radiation source, then the device integration is high, but the imaging area and direction change according to radiographic imaging conditions causing inconvenience
Solution Approach 1:
The system establishes a feedback mechanism where radiographic imaging conditions (SID, imaging part, detector size) are detected and used to automatically adjust the optical camera's imaging conditions. This closed-loop control ensures the optical image remains consistent and reliable despite changes in radiographic parameters.
Solution Approach 2:
An optical imaging condition setter acts as an intermediary between the radiographic imaging system and the optical camera. This mediator receives radiographic imaging conditions and translates them into appropriate camera settings, decoupling the direct dependency while maintaining integration benefits.
3Ease of operation
If the angle of view is adjusted to maintain consistent imaging area when SID changes, then the optical image usability is improved, but the control system complexity increases
Solution Approach 1:
The optical imaging condition setter serves multiple functions: it receives radiographic imaging conditions, calculates appropriate camera settings, and controls the camera's angle of view and direction. This multi-functional component adds intelligence to the system while maintaining a relatively simple overall architecture.

AI summary
A radiographic imaging system includes a radiographic imager, an optical imager and an optical imaging condition setter. The radiographic imager detects radiation emitted from a radiation source and passed through a subject to take a radiograph. The optical imager takes an optical image of a region including a region to which the radiation is emitted from the radiation source. The optical imaging condition setter sets an optical imaging condition of the optical imager based on a radiographic imaging condition for the radiograph.
