Separable Gantry Imaging System for Hybrid Angiography and CBCT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current angiography machines require multiple scanning rooms for different imaging modes, leading to increased treatment time and radiation exposure due to the need for subjects to be moved between rooms for various scans.
Innovation Solution
An imaging system comprising a first imaging device and a separable second gantry that can operate independently or combine to perform both angiographic and Cone Beam Computed Tomography (CBCT) modes, allowing for flexible scanning without the need to move the subject between rooms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple scanning rooms are used for different imaging modes, then imaging functionality is comprehensive, but treatment time increases and radiation exposure increases due to subject relocation
Solution Approach 1:
The patent combines multiple imaging modes (angiography and CBCT) into a single integrated imaging system. The gantry houses both an X-ray source/detector for angiography and a cone beam X-ray source/detector for CBCT, allowing both imaging functionalities to coexist in one room. This eliminates the need to move subjects between separate scanning rooms, thereby reducing treatment time while maintaining comprehensive imaging capabilities.
2Adaptability or versatility
If multiple scanning rooms are used for different imaging modes, then imaging functionality is comprehensive, but radiation exposure increases due to repeated positioning and relocation
Solution Approach 1:
The patent merges multiple imaging modalities into one integrated system, allowing subjects to remain in a single position throughout the procedure. The unified gantry structure enables switching between angiography and CBCT modes without relocating the subject, thereby reducing cumulative radiation exposure from repeated positioning and transport while maintaining comprehensive diagnostic capabilities.
3Stability of the object's composition
If a fixed gantry structure is used, then structural stability is high, but adaptability to different imaging modes is limited
Solution Approach 1:
The patent designs the gantry with multi-functionality to accommodate different imaging modes. The gantry includes both a conventional X-ray source/detector arrangement for angiography and a cone beam X-ray source/detector system for CBCT imaging. This universal design allows the same structural platform to perform multiple imaging functions, achieving both structural stability and adaptability to different imaging modes.
