Radiation Image Correction for Biomagnetism Superimposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems cannot easily superimpose biomagnetism data onto radiation images due to positional discrepancies between the radiation image capture and biomagnetism detection, making accurate alignment challenging.
Innovation Solution
An image processing apparatus that captures radiation images from orthogonal directions, corrects one image based on positional information of the imaging device or specific subject regions, and generates a superimposed image by combining corrected radiation images with current distribution data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radiation images are captured from opposite directions and biomagnetism is detected inside the body, then both external radiation imaging and internal biomagnetism detection are achieved, but the radiation image position does not align with the biomagnetism data position making superimposition difficult
Solution Approach 1:
The patent introduces an image correction unit that acts as an intermediary to transform the radiation image into a coordinate system that matches the biomagnetism detection position. The correction unit uses positional information about the imaging device and subject anatomy to adjust the radiation image coordinates, enabling accurate superimposition with the biomagnetism data without requiring both devices to share the same physical coordinate system
Solution Approach 2:
The patent changes the coordinate system parameters of the radiation image through mathematical transformation. The image correction unit modifies the positional parameters (x, y, z coordinates) of the radiation image pixels based on the imaging device position and subject anatomy, converting them to match the biomagnetism detection coordinate system, thereby resolving the positional mismatch
2Area of stationary object
If radiation images are captured from multiple directions, then comprehensive imaging coverage is achieved, but complex correction processing is required to align images from different directions
Solution Approach 1:
The image correction unit is designed with multi-functionality to handle various imaging directions and configurations. It can process radiation images from any direction by using the imaging device positional information and performing appropriate coordinate transformations, making the correction system universally applicable regardless of the number or orientation of imaging devices
Solution Approach 2:
The patent uses parameter-based coordinate transformation to simplify multi-directional image alignment. By changing the coordinate system parameters (rotation angles, translation vectors) based on imaging device positions, the system can automatically adapt to different imaging configurations without requiring complex case-specific processing for each direction

AI summary
An image processing apparatus includes a processor programmed to obtain a first radiation image of a subject captured from a first direction, obtain a second radiation image of the subject captured from a second direction that intersects the first direction, and either correct one of the first radiation image and the second radiation image based on positional information of a device for capturing the one of the first radiation image and the second radiation image, or correct another one of the first radiation image and the second radiation image based on information on a position of a specific region of the subject obtained from the one of the first radiation image and the second radiation image.
