Medical Data Processing Device for MIP Image Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MIP image generation methods are obstructed by body surface radiopharmaceutical concentration, leading to masking of internal radiopharmaceutical distribution and potential oversight of cancer tissues, especially in PET apparatus diagnostics.
Innovation Solution
A medical-data processing device with a body-surface intensity adjusting mechanism that decreases the intensity of the body surface region in three-dimensional space data, allowing the selection of maximum intensity from non-body surface areas to generate MIP images, thereby avoiding body surface projection and enhancing internal visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional MIP image generation is used, then the image generation process is simple, but the body surface radiopharmaceutical concentration masks internal radiopharmaceutical distribution
Solution Approach 1:
The patent segments the three-dimensional data into body surface region and internal region by identifying the body surface contour. This segmentation allows separate processing of body surface voxels (deletion or intensity reduction) from internal voxels, enabling the MIP image to display internal radiopharmaceutical distribution without masking from body surface concentration.
Solution Approach 2:
The patent extracts and removes body surface voxels from the three-dimensional data before generating the MIP image. By identifying the body surface contour and deleting voxels outside this contour, the harmful body surface radiopharmaceutical concentration is extracted and removed, allowing clear visualization of internal radiopharmaceutical distribution.
2Measurement precision
If body surface intensity is reduced, then internal structure visibility improves, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary action by identifying the body surface contour and deleting or adjusting body surface voxel intensities before the MIP image generation process. This preliminary processing eliminates the need for complex post-processing or filtering during MIP generation, as the body surface interference is removed in advance, simplifying the overall workflow.
Solution Approach 2:
The patent applies local quality by differentiating between body surface region and internal region, applying different processing strategies to each. Body surface voxels are deleted or have their intensities reduced, while internal voxels are processed normally for MIP generation. This localized approach improves internal visibility without unnecessarily complicating the entire processing pipeline.

AI summary
The disclosure has an object to provide a medical-data processing device that allows generation of an MIP image suitable for diagnosis. With the medical-data processing device of the disclosure, intensity of a body surface region in three-dimensional space data is adjusted. The body surface region corresponds to a body surface of a stereoscopic image of a subject. Since the intensity of the body surface region is adjusted to be decreased, the maximum intensity is selected from a portion except for the body surface region to generate the MIP image. This prevents the body surface of the subject from appearing upon generating the MIP image. Therefore, the MIP image is obtainable having excellent visibility to the inside of the subject.
