Ultrasonic Diagnostic Apparatus MPR Polar Map Positional Correspondence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic diagnostic apparatuses face difficulties in visually confirming the relative positional correspondence between multi-planar reconstruction (MPR) images, polar map images, and three-dimensional images, making it challenging to determine the position correspondence between these images.
Innovation Solution
The apparatus generates and displays support information indicating the positional correspondence relationship between MPR images, polar mapping images, and three-dimensional images, using volume data and tissue motion information to facilitate easy visualization of heart wall motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple images (MPR, polar map, three-dimensional) are displayed to provide comprehensive tissue motion information, then the information completeness is improved, but the difficulty of understanding positional correspondence relationship increases
Solution Approach 1:
The patent introduces a polar map image as an intermediary that serves as a common reference framework between MPR images and three-dimensional images. The polar map displays tissue motion information in a standardized circular format that acts as a mediator, allowing users to understand positional relationships across different image types by referencing the polar map's consistent coordinate system and segmentation patterns.
Solution Approach 2:
The patent employs color-coded segmentation markers that are consistently applied across all image types (MPR, polar map, and three-dimensional images). Specific colors represent corresponding tissue segments in different views, enabling users to track and understand positional relationships through visual color matching rather than relying on complex spatial reasoning.
2Device complexity
If conventional display methods are used for multiple image types, then device complexity is reduced, but diagnostic efficiency decreases due to difficulty in grasping relative positional relationships
Solution Approach 1:
The patent divides the display system into segmented, color-coded regions that correspond across different image types. By segmenting the visual information into distinct, color-marked zones that maintain consistent spatial relationships, the system enables rapid comprehension of positional correspondences without increasing overall system complexity. Each segment acts as an independent visual cue that can be quickly processed.

AI summary
When displaying a plurality of images in different conformations in relation to information of a tissue motion typified by a heart wall motion, support information which is used to rapidly and easily visually confirm a relative positional correspondence relationship between an MPR image, a polar mapping image, and a three-dimensional image is generated and displayed. A marker indicative of a desired local position is set and displayed as required. Further, a position corresponding to the set or changed marker may not be present on the MPR image. In such a case, the MPR image always including a position corresponding to the set or changed marker is generated and displayed by automatically adjusting a position of an MPR cross section.
