Description
Technical field
The present invention relates to a kind of armarium mechanical precision mobile device, relate in particular to a kind of automatic pendulum level controlling system and control method thereof that is used at the therapeutic bed of radiotherapy equipment such as linear accelerator.
Background technology
Medical accelerator is a kind of device that can quicken charged particle.Can produce X ray after the high-energy particle bombardment metallic target that is accelerated, this of generation kind of X ray often can be used in tumor resection.So medical accelerator usually is called as the X ray cutter again.In carrying out radiocurable process, require X ray accurately to beat, otherwise just can cause treatment not thorough at knub position, perhaps injure human normal tissue cell.But, using in the process of medical accelerator in reality, the doctor reflects that generally accurately putting therapeutic bed is a pretty troublesome thing.The up-down of control bed, front and back, about often neither one effectively install and unifiedly carry out numerical control operating, also the neither one device can carry out Remote easily, thereby can not make things convenient for, removing patient position intelligently.
Therefore, be necessary to provide a kind of improved accelerator to put level controlling system and control method thereof automatically to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of accelerator that carries out automatization, the position control of high accuracy pendulum to put level controlling system and control method thereof automatically.
For realizing the foregoing invention purpose; The invention provides a kind of accelerator and put level controlling system automatically; The computer, infrared tracing-positioning system, power supply and the control circuit case that comprise accelerator, be adsorbed on control box on the accelerator, be connected through connection with said control box; Said accelerator comprises therapeutic bed, and said computer installation has pendulum position control software module.
As further improvement of the present invention, said pendulum position control software module comprises according to infrared tracing-positioning system carries out the data acquisition module of data acquisition and the data processing module that data analysis is handled to the therapeutic bed locus.
As further improvement of the present invention, said infrared tracing-positioning system is the Polaris optical tracking system.
For realizing the foregoing invention purpose, the present invention also provides a kind of accelerator to swing control method automatically, may further comprise the steps:
Infrared tracing-positioning system is provided, and the locus that utilizes this infrared tracing-positioning system to read therapeutic bed also sends to computer with this locus;
Computer carries out the movement locus of digitized record therapeutic bed to form dynamic data according to the locus of therapeutic bed;
Dynamic data is handled and sent instruction according to the data after handling to control box;
The control box execution command is accurately put the position with the therapeutic bed to accelerator.
As further improvement of the present invention, said infrared tracing-positioning system is the Polaris optical tracking system.
The invention has the beneficial effects as follows: level controlling system put automatically by accelerator of the present invention and control method can be passed through the locus that infrared tracing-positioning system is gathered therapeutic bed, reaches dynamic moving and controls the therapeutic bed of accelerator is realized steady, quick, high accuracy.
Description of drawings
Fig. 1 is the structured flowchart that accelerator of the present invention is put level controlling system automatically.
The specific embodiment
Below will combine each embodiment shown in the drawings to describe the present invention.But these embodiments do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in protection scope of the present invention.
Please combine shown in Figure 1ly, accelerator of the present invention is put computer, infrared tracing-positioning system, power supply and the control circuit case that level controlling system comprises linear accelerator, is adsorbed on control box on the linear accelerator, is connected through connection with said control box automatically.Said linear accelerator comprises therapeutic bed.Said linear accelerator is provided with the Artificial Control panel, and said control box is to be adsorbed on the Artificial Control panel so that linear accelerator is controlled.Said computer is more than the intel pentium 4 processor 2.2Ghz, and is provided with pendulum position control software module.Said pendulum position control software module comprises the data acquisition module the spatial position data of therapeutic bed gathered according to infrared tracing-positioning system and to the data processing module of dynamic data analyzing and processing.Said infrared tracing-positioning system is Polaris optical tracking system (Polaris Optical Tracking System), and the detection accuracy of this infrared tracing-positioning system has the above resolution of 0.5mm.Said control box has three kinds of control models to the accelerator therapy bed accessory: the spatial position data of the therapeutic bed that first kind of pattern gathered according to infrared tracing-positioning system for the doctor on computers directly through about the control box control therapeutic bed, about and before and after move; Second kind of pattern is the spatial position data according to the therapeutic bed of infrared tracing-positioning system collection, and through setting the position that specified coordinate comes the locating therapy bed to put; The third pattern for through data processing module directly according to data acquisition module from the position that the data computation of infrared tracing-positioning system collection will move, send instruction then and move to the target location automatically with the control therapeutic bed for control box.Thus, make that through these three kinds of patterns the therapeutic bed of accelerator can be realized steadily, quick, high accuracy, dynamic mobile.
Accelerator of the present invention is swung control method automatically, may further comprise the steps:
Infrared tracing-positioning system is provided, and the locus that utilizes this infrared tracing-positioning system to read therapeutic bed also sends to computer with this locus;
Computer carries out the movement locus of digitized record therapeutic bed to form dynamic data according to the locus of therapeutic bed;
Dynamic data is handled and sent instruction according to the data after handling to control box;
The control box execution command is accurately to put the position to accelerator.
Got by above, level controlling system put automatically by accelerator of the present invention and control method can be passed through the locus that infrared tracing-positioning system is gathered therapeutic bed, reaches dynamic moving and controls the therapeutic bed of accelerator is realized steady, quick, high accuracy.
Be to be understood that; Though this description is described according to embodiment; But be not that each embodiment only comprises an independently technical scheme, this narrating mode of description only is for clarity sake, and those skilled in the art should make description as a whole; Technical scheme in each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
