Medical Imaging 3D Positioning Guidance for Complex Joint Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical imaging systems struggle to accurately position subjects in three-dimensional space for radiation imaging, particularly for complex joints like the knee and wrist, due to difficulties in comprehensively managing multiple parameters such as flexion and rotation angles, making it challenging to achieve precise alignment for effective comparison and diagnosis.
Innovation Solution
A medical imaging system that utilizes three-dimensional positioning data to specify the position, posture, and shape of the subject, incorporating a display unit to show the ideal arrangement with wireframe or solid models, and a determination unit to prevent imaging if deviations exceed a threshold, along with a generation unit to create positioning data from detected subject information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-dimensional arrangement support display is used to position the subject, then the display method is simple, but the positioning accuracy is insufficient for complex three-dimensional arrangements
Solution Approach 1:
The patent transitions from two-dimensional display to three-dimensional wireframe model display to represent subject arrangement. The processing unit generates a wireframe model that three-dimensionally depicts the subject's position, posture, and shape, allowing operators to comprehensively understand complex spatial arrangements that cannot be fully captured in 2D views alone.
2Loss of information
If multiple two-dimensional views are displayed to achieve three-dimensional positioning, then more information is provided, but the complexity of interpretation increases
Solution Approach 1:
The patent merges multiple two-dimensional arrangement information into a single integrated three-dimensional wireframe model. Instead of requiring operators to mentally integrate separate 2D views, the system combines all spatial information (position, posture, shape) into one unified 3D visual representation that conveys complete arrangement information more efficiently.
Solution Approach 2:
By adding the third dimension to the display, the system naturally incorporates depth and spatial relationships that would require multiple 2D views to represent. The wireframe model's three-dimensional structure inherently encodes positional and postural information that would otherwise require complex multi-view presentations.

AI summary
Provided are a medical imaging system and a medical imaging processing apparatus capable of supporting more accurate and easy positioning of a subject than in a case of performing two-dimensional arrangement support display of the subject. A medical imaging system (10) includes an imaging unit (11) that obtains a medical image or data used for generating the medical image by imaging a subject (Obj), a processor that stores positioning data (35) for specifying arrangement of the subject (Obj) with respect to the imaging unit (11), and a display unit (33) that three-dimensionally displays the arrangement of the subject (Obj) with respect to the imaging unit (11) by using the positioning data (35) in a case where the subject (Obj) is imaged using the imaging unit (11).
