Radiographic Image Rotation Based on Irradiation Field Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiographic imaging, when the irradiation field region is inclined relative to the X-ray detector, existing techniques require manual rotation and magnification adjustments to display the image correctly, leading to inefficiencies and potential inclusion of unnecessary regions in the diagnosis image.
Innovation Solution
A radiographic image processing apparatus and method that specifies the irradiation field region, calculates a rotation angle based on this region, rotates the image accordingly, and controls the display to ensure accurate and efficient presentation of the irradiation field region on the display unit, thereby eliminating the need for manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the irradiation field region is displayed in an enlarged manner as a diagnosis image, then the irradiation field region can be displayed on the display unit, but a large region other than the irradiation field region is included requiring manual rotation and magnification adjustment
Solution Approach 1:
The system automatically calculates the rotation angle based on the irradiation field region's geometric characteristics and pre-rotates the image before display. This preliminary action eliminates the need for manual rotation operations by the operator, directly resolving the contradiction between ease of display and operation complexity.
Solution Approach 2:
The image processing apparatus performs self-adjustment by automatically determining the rotation angle and executing the rotation without operator intervention. The system serves itself by computing the appropriate rotation parameters and applying them, thereby reducing operational complexity while maintaining display effectiveness.
2Adaptability or versatility
If manual rotation and magnification adjustment are performed by the operator, then the image can be adjusted to suit diagnosis requirements, but time is consumed and workflow efficiency is reduced
Solution Approach 1:
The system performs the rotation adjustment in advance based on pre-calculated rotation angles derived from the irradiation field region's geometry. This preliminary action ensures the image is already optimized for diagnosis before the operator needs to view it, eliminating time-consuming manual adjustments while preserving the ability to adapt to different diagnostic requirements.
Solution Approach 2:
The system uses feedback from the irradiation field region's geometric parameters to automatically determine the rotation angle. This feedback mechanism ensures the rotation is precisely tailored to the actual imaging conditions, providing adaptability without requiring manual intervention and thus maintaining high workflow efficiency.
3Reliability
If a rectangular irradiation field inclusive region is displayed, then the irradiation field region is included in the display, but the display includes unnecessary regions increasing the displayed area
Solution Approach 1:
The system calculates the precise rotation angle based on the irradiation field region's geometric parameters and applies this rotation before display. This preliminary action ensures that the irradiation field region is correctly oriented and minimally adjusted, displaying only the necessary area while maintaining diagnostic reliability by preserving the accurate spatial relationship of the irradiated region.
