Medical Image Processing for Single-Slice 3D Region Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designating a three-dimensional region on a viewer displaying designated tomographic images from CT or MRI devices is time-consuming and inefficient, with existing methods lacking information on the region of interest.
Innovation Solution
A medical image processing device that determines a three-dimensional region by receiving a rectangular region on a displayed tomographic image, calculates a normal line based on this region, and performs image processing on the defined rectangular parallelepiped, displaying the results alongside the original image.

Engineering Contradiction Analysis
1Measurement precision
If a user designates a three-dimensional region by manually specifying regions in each tomographic image, then the region designation can be performed with high precision, but the time and effort required increases significantly
Solution Approach 1:
The system performs preliminary actions by automatically generating a three-dimensional region based on a rectangular region designated in a single tomographic image. The processor determines the rectangular parallelepiped region by extending the two-dimensional rectangular region into three dimensions using the normal line direction, eliminating the need for manual designation in each individual image slice.
Solution Approach 2:
The system transitions from two-dimensional region designation in a single tomographic image to three-dimensional region determination by introducing the normal line dimension. The processor extends the rectangular region along the normal line direction to create a rectangular parallelepiped, effectively adding a third dimension to the region definition process.
2Ease of operation
If existing methods calculate height in normal direction to acquire rectangular parallelepiped, then the three-dimensional region can be defined, but information on the region of interest is not provided
Solution Approach 1:
The system implements feedback by displaying the determined three-dimensional rectangular parallelepiped region on the display device. This allows the user to visually confirm the generated region and verify that it accurately represents the intended region of interest, providing immediate feedback on the automatic region determination result.
