Mapping Imaged Ranges on Human Body Model for Medical Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in easily understanding and comparing imaged ranges from various medical examinations, as existing systems often rely on inaccurate or incomplete information stored in DICOM formats, making it hard to visualize and compare the actual imaged areas across different examinations.
Innovation Solution
A medical image display apparatus that identifies imaged ranges based on anatomical information from medical images, maps these ranges onto a standard human body model, and displays them in an intuitive format, allowing users to visualize and compare imaged areas accurately across multiple examinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If imaged range information is stored in DICOM formats, then medical images can be stored and transmitted, but the accuracy and completeness of imaged range information is insufficient
Solution Approach 1:
The patent introduces a body model as an intermediary representation that mediates between raw DICOM image data and the desired imaged range information. The body model serves as a standardized framework that integrates anatomical information from multiple examinations, enabling accurate determination of imaged ranges without relying solely on potentially incomplete DICOM metadata.
Solution Approach 2:
The patent transitions from two-dimensional image data to a three-dimensional body model representation. By mapping imaged ranges onto a standardized three-dimensional human body model, the system achieves more precise and complete spatial information about examined areas, overcoming the limitations of traditional two-dimensional DICOM storage.
2Adaptability or versatility
If multiple medical examinations are performed on the same subject, then comprehensive diagnostic information is obtained, but it becomes difficult to compare imaged ranges across examinations
Solution Approach 1:
The patent creates a universal body model that can accommodate and display imaged ranges from multiple different medical examinations. This standardized representation serves multiple functions: storing anatomical information, comparing across examinations, and visualizing imaged ranges consistently, thereby making comprehensive diagnostic information easy to navigate and compare.
Solution Approach 2:
The patent establishes a standardized body model framework that provides a common reference system for all examinations. By mapping all imaged ranges onto this equipotential standardized framework, the system eliminates differences in representation across examinations, making comparison straightforward and intuitive for users.
3Measurement precision
If imaged ranges are mapped onto a standard human body model, then visualization accuracy is improved, but system complexity increases
Solution Approach 1:
The patent uses a standardized body model as a template or copy that represents human anatomy. By mapping imaged ranges onto this pre-established body model copy, the system achieves accurate visualization without requiring complex real-time computation or customization for each patient, thus managing system complexity while improving visualization accuracy.

AI summary
A medical image display apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to: identify imaged ranges respectively corresponding to a plurality of examinations, on the basis of anatomical information from a plurality of medical images taken of an examined subject in the plurality of examinations; map the imaged ranges respectively corresponding to the plurality of examinations onto a single human body model; and cause a display unit to display a list of information about the plurality of examinations and the human body model on which the imaged ranges respectively corresponding to the plurality of examinations are mapped, so as to be kept in correspondence with each other.
