Solution Overview
Problem
Current radiotherapy devices face challenges in positioning accuracy due to reliance on separate imaging systems, leading to large positioning errors and complex, time-consuming installation and debugging processes.
Innovation Solution
A radiotherapy device with an integrated imaging system comprising a ray emitter and detector disposed oppositely on a fixed machine frame, allowing for improved positioning accuracy and reduced installation time by integrating the imaging device with the radiotherapy device, with optional support arms for movement relative to the treatment couch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate imaging system disposed on floor and ceiling is adopted for positioning, then the positioning function is achieved, but the locating accuracy is low and the installation and debugging process is complicated and long in cycle
Solution Approach 1:
The imaging device is integrated into the radiotherapy device structure, combining the imaging system and radiotherapy treatment system into a unified device. This integration eliminates the need for separate floor and ceiling imaging systems, thereby improving locating accuracy through coordinated positioning and significantly simplifying the installation and debugging process by reducing the number of independent systems that need to be configured and aligned.
Solution Approach 2:
The radiotherapy device is designed to perform multiple functions: radiotherapy treatment and imaging/positioning. By incorporating the imaging device within the same structural framework, the system achieves both therapeutic and diagnostic capabilities, eliminating the need for separate dedicated imaging systems and reducing overall system complexity.
