3D Diagnostic Image Processing for CT Material Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The storage space shortage and increased diagnosis time issues arise when multiple types of images, such as CT and material discrimination images, are acquired for the same subject, necessitating improved image processing and display methods.
Innovation Solution
An information processing apparatus and method that combines CT and material discrimination images into a single projection image, using intensity projection methods to create development images and display them on a device, thereby reducing storage needs and diagnosis time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple types of images (CT image and material discrimination image) are acquired for the same subject, then diagnosis accuracy is improved, but storage space is insufficient and diagnosis time increases
Solution Approach 1:
The patent combines multiple types of images (CT image and material discrimination image) into a single integrated projection image. The processor projects feature amount distributions from the material discrimination image onto the CT image, creating one unified image that contains both structural and material information, thereby eliminating the need to store and display multiple separate images.
Solution Approach 2:
The projection image serves multiple functions simultaneously: it displays the three-dimensional structure from the CT image while superimposing material distribution information from the material discrimination image. This multi-functional image can be used for various diagnostic purposes without requiring separate specialized images for each analysis type.
2Measurement precision
If multiple types of images are displayed side by side on the display device, then diagnosis accuracy is improved, but diagnosis time increases
Solution Approach 1:
The patent merges multiple images into a single projection image that integrates both structural and material information. By displaying only this unified image rather than multiple separate images side by side, the diagnosis time is reduced while maintaining comprehensive diagnostic capability through the integrated information presentation.
3Loss of information
If multiple types of images are acquired and stored, then comprehensive diagnostic information is obtained, but storage space becomes insufficient
Solution Approach 1:
The patent combines multiple image datasets into a single projection image that preserves comprehensive diagnostic information. The processor integrates the three-dimensional structural data from CT images with material distribution data from material discrimination images, creating one consolidated image that contains all necessary diagnostic information without requiring separate storage for each image type.

AI summary
An information processing apparatus according to an embodiment of the present disclosure includes a processor configured to: read a first image indicating a three-dimensional form of a subject and a second image indicating a three-dimensional distribution of feature amounts of the subject; extract a diagnosis target from the first image; two-dimensionally develop the diagnosis target based on the first image to create a first development image; project the distribution of the feature amounts included in the diagnosis target onto the first development image based on the second image to create a projection image; and display the projection image on a display device.
