Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current X-ray diagnostic systems face challenges in efficiently setting the direction of X-rays for real-time imaging during intravascular treatments, as they rely on manual selection of three-dimensional medical image data to align the X-ray emission direction, which can be time-consuming and prone to errors.
Innovation Solution
A medical information processing apparatus that displays three-dimensional medical image data and creates a figure indicating the movable region of an X-ray diagnostic apparatus, allowing operators to intuitively set the direction of X-ray emission by rotating the image data and visualizing the movable components' range, thereby facilitating accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection of three-dimensional medical image data is used to align X-ray emission direction, then the target region can be observed, but the process becomes time-consuming and complex
Solution Approach 1:
The system pre-calculates and stores optimal X-ray emission directions based on three-dimensional medical image data before the actual procedure. When setting up for imaging, the operator can directly select from pre-computed directional options rather than manually adjusting and calculating directions in real-time, significantly reducing setup time while maintaining alignment accuracy.
Solution Approach 2:
The system introduces a computational intermediary that automatically processes the alignment between three-dimensional medical image data and X-ray emission directions. This intermediary component performs the complex calculation and transformation tasks, replacing manual operator adjustments and reducing both time and complexity of the alignment process.
2Ease of operation
If manual rotation of three-dimensional medical image data is performed to set X-ray direction, then the desired observation angle can be achieved, but the operation becomes complex and error-prone
Solution Approach 1:
The system enables self-service operation where the three-dimensional medical image data automatically aligns with the X-ray emission direction based on pre-stored positional and directional information. The operator simply needs to select the target region, and the system automatically performs the alignment without requiring manual rotation operations, thereby improving both ease of operation and reliability.
Solution Approach 2:
The system replaces the mechanical manual rotation operation with an automated computational process. Instead of operators physically rotating the three-dimensional image data to match X-ray directions, the system uses computer-based transformation and calculation to achieve automatic alignment, eliminating human error and simplifying the operation.
3Manufacturing precision
If complex manual adjustment is used to align X-ray emission direction with target region, then accurate imaging can be achieved, but the device complexity and operation difficulty increase
Solution Approach 1:
The system performs preliminary calculation and storage of X-ray emission directions based on three-dimensional medical image data before the actual imaging procedure. This pre-processing step captures the complex alignment relationships in advance, allowing the imaging system to simply retrieve and apply pre-determined directional parameters, thereby maintaining imaging accuracy while reducing operational complexity.
Solution Approach 2:
The system creates a computational model or copy of the anatomical structure from three-dimensional medical image data, and uses this model to determine optimal X-ray emission directions. This copying approach allows the system to work with simplified representations rather than complex real-time adjustments, reducing operational complexity while maintaining imaging precision.

AI summary
A medical information processing apparatus according to an embodiment causes a display to display a three-dimensional medical image, receives an operation of rotating direction of the three-dimensional medical image on the display, creates a figure indicating, in a case the three-dimensional medical image is rotated through the rotating operation, whether a movable member of an X-ray diagnostic apparatus can reach a position corresponding to the direction of the three-dimensional medical image after the rotation, based on the direction of the three-dimensional medical image on the display before the rotation, and causes the display to further display the figure.
