Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current angiography machines face challenges in efficiently adjusting the position and angle of X-ray sources and detectors during imaging procedures, leading to potential increased radiation exposure and longer treatment times, especially in interventional operations.
Innovation Solution
The design incorporates a separable cantilever system with an aligning and locking device, allowing for precise alignment and locking of cantilevers, enabling the X-ray source and detector to rotate 360 degrees or more, facilitating Cone Beam Computed Tomography (CBCT) mode imaging without the need for a separate CT scanner, thus reducing radiation dose and treatment time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the X-ray source and detector are positioned using traditional fixed or limited-range mechanisms, then the device structure remains simple, but the imaging angles and positions are limited, requiring multiple devices or rooms for comprehensive imaging
Solution Approach 1:
The patent implements a dynamic positioning system where the cantilever can rotate 360 degrees or more around the patient, allowing the X-ray source and detector to achieve various imaging angles and positions. This dynamic structure replaces traditional fixed or limited-range positioning mechanisms, enabling comprehensive imaging from multiple angles without requiring multiple separate devices or scanning rooms.
2Adaptability or versatility
If multiple separate imaging devices are used to achieve comprehensive imaging coverage, then complete imaging coverage is obtained, but the treatment time increases and the patient receives higher radiation exposure
Solution Approach 1:
The patent combines the X-ray source, detector, and rotating cantilever into a single integrated imaging system that can achieve 360-degree or greater coverage. This merged system eliminates the need for multiple separate imaging devices, allowing comprehensive imaging to be performed in one continuous process, thereby reducing treatment time and minimizing patient radiation exposure through efficient single-session imaging.
3Ease of operation
If traditional angiography machines use fixed imaging positions, then the device operation is simple, but the radiation exposure increases due to the need for multiple positioning adjustments
Solution Approach 1:
The patent employs a dynamically adjustable cantilever system that can rotate to any required angle and position around the patient. This dynamic positioning capability allows the imaging system to reach optimal imaging positions without requiring multiple separate positioning adjustments or repeated imaging attempts, thereby reducing the cumulative radiation exposure to the patient while maintaining ease of operation through automated or semi-automated positioning control.
