Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biplane X-ray diagnostic apparatuses face challenges in efficiently generating three-dimensional vascular images for interventional treatments due to the complexity of vascular structures and the need for independent control of imaging systems, which complicates the process and increases exposure time and contrast agent usage.
Innovation Solution
The X-ray diagnostic apparatus synchronizes the rotating centers of its two imaging systems, allowing for simultaneous rotation imaging with identical centers, reducing the need for separate data collection and minimizing exposure time by enabling the medical doctor to observe target regions from two angles without moving the systems, thus simplifying the generation of three-dimensional roadmaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two imaging systems are controlled independently for biplane imaging, then imaging flexibility is improved, but system complexity and operation difficulty increase
Solution Approach 1:
The patent merges the control of two imaging systems by synchronizing their rotating centers to a common position. This allows the systems to rotate simultaneously around the same axis, reducing operational complexity while maintaining the ability to capture images from multiple angles for three-dimensional reconstruction.
2Loss of information
If separate data collection is performed for each imaging system, then imaging completeness is improved, but exposure time and contrast agent usage increase
Solution Approach 1:
The patent implements continuous simultaneous rotation of both imaging systems around a common center, allowing data collection to occur continuously without interruption. This eliminates the need for separate data collection phases, reducing total exposure time and contrast agent usage while maintaining complete vascular structure information.
3Ease of operation
If imaging systems rotate around different centers, then individual system control is simplified, but three-dimensional image generation complexity increases
Solution Approach 1:
The patent combines the rotation centers of both imaging systems to a common position, which simplifies the three-dimensional image generation process. When both systems rotate around the same center, the coordinate systems align more easily, reducing the mathematical complexity of merging the datasets for three-dimensional reconstruction.

AI summary
An X-ray diagnostic apparatus according to an embodiment includes a first imaging system, a second imaging system, and processing circuitry. The first imaging system holds a first X-ray tube and a first X-ray detector in a rotatable manner. The second imaging system holds a second X-ray tube and a second X-ray detector in a rotatable manner, and rotating centers, which are capable to set independently, between the first imaging system and the second imaging system. The processing circuitry makes a rotating center of the first imaging system and the rotating center of the second imaging system substantially equivalent to each other when a rotation imaging program using the first imaging system and the second imaging system is selected.
