Abstract
The invention discloses a thoracico-abdominal surface breathing movement signal super-resolution circuit and belongs to the technical field of precise instruments and thoracico-abdominal radiotherapy.The circuit comprises a signal conversion module, a phase difference multi-output module, a resistance chain multi-phase generation module, a multi-phase sine square wave conversion module, a multi-phase fusion logic gate module and a secondary super-resolution module. The modules function as a whole and not a single one can be omitted, the purpose that breathing movement signals of a cycle are converted into square wave signals of multiple cycles is achieved together, that is, super resolution of thoracico-abdominal surface breathing movement signals is achieved, the result brings further technical advantages that in the process of multiple breathing cycles, variation of breathing frequency can be judged by judging variation of the frequency of the square wave signals, more importantly,since the cycle of super-resolution square waves is far smaller than a breathing movement cycle, variation of the breathing frequency can be judged within a shorter period of time, that is, within a time range smaller than a breathing cycle.
Description
technical field [0001] The invention relates to a super-resolution circuit for respiratory motion signals on the surface of the chest and abdomen, belonging to the technical fields of precision instruments and radiation therapy of the chest and abdomen. Background technique [0002] During radiotherapy for thoracic and abdominal tumors, breathing makes the tumor area escape the target area or normal tissue enter the target area, which not only reduces the effect of radiotherapy, but also easily causes complications. [0003] In order to solve the negative impact of respiratory exercise on radiation therapy, the methods of respiratory maintenance and respiratory gating were first adopted clinically, and the control of tumor location was achieved through the intervention of breathing. Although some effects have been achieved, the patient's tolerance is poor. ; In order to improve the patient's tolerance and not interfere with the patient's breathing, a tracking system has emer...
