Apparatus for evaluating radiation therapy plan based on respiratory motion of patient

摘要

The present invention relates to a technique for evaluating a radiation treatment plan, and more specifically, an evaluation device capable of verifying a radiation treatment plan of a practitioner by simulating a patient-specific real-time breathing exercise in consideration of irregular patient movement such as breathing exercise It is about. An object of the present invention is to provide a device for evaluating a radiation treatment plan based on a patient's breathing motion that can minimize an error of a simulated breathing motion in realizing a patient's breathing motion. An apparatus for evaluating a radiation treatment plan based on a patient's breathing motion according to an exemplary embodiment of the present invention includes an inner driving unit having a motor for each of the three-axis motions and providing a three-axis motion; An inner motor driver installed on the inner driving unit to drive the three-axis movement; An outer driving part having a motor for each of the three-axis motions separate from the three-axis motion of the inner driving part and providing a three-axis motion; And an outer motor driver installed on the outer driving part to drive a three-axis motion. The present invention can minimize the error of the simulated breathing motion that may occur according to the distance difference between each of the six motor motor drivers and the motor in the simulation of the patient's breathing motion.
