Abstract
The utility model belongs to a zero control device of a medical accelerator collimator, and especially relates to a zero calibrating device of the medical accelerator collimator. The zero calibrating device includes a collimator tungsten gate which is arranged on a track. The zero calibrating device is characterized in that the device is provided with a processor and a collimator zero acquisition unit; the input terminal of the processor is connected with the output terminal of the collimator zero acquisition unit; and the collimator zero acquisition unit is arranged on one side of the collimator track. The zero calibrating device of the medical accelerator collimator can accurately calibrate the zero of the accelerator collimator to guarantee the high repeated positioning precision, and on the basis, the zero calibrating device can accurately control the position of the collimator to improve the radiotherapy effect.
Description
Technical field
This utility model belongs to the collimator zero set control of medical accelerator, particularly a kind of collimator zero adjustment device of medical accelerator.
Background technology
Collimator is the radiation head building block of medical accelerator.At present, the medical accelerator collimator is not installed the zero adjustment device, and the zero-bit of collimator relies on the feedback of potentiometer to obtain, and error is larger.After the collimator operation repeatedly, repetitive positioning accuracy is poor, affects radiotherapeutic effect.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: providing a kind of can carry out accurate calibration to the collimator zero-bit of accelerator, guarantee higher repetitive positioning accuracy, on this basis, can carry out Accurate Position Control by the collimation device, improve the collimator zero adjustment device of the medical accelerator of radiotherapeutic effect.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of collimator zero adjustment device of medical accelerator, comprise collimator tungsten door, the setting of collimator tungsten door in orbit, it is characterized in that: set handling device and collimator zero-bit collecting unit, the input of processor arranges the outfan that connects collimator zero-bit collecting unit, and collimator zero-bit collecting unit is arranged on a side of collimator track.
Collimator zero-bit collecting unit gathers the collimator position signal, then signal is returned processor and processes.This collecting unit is on-mechanical formula sensor, and easy to use accurately the life-span is long, and precision is high.
Wherein preferred version is:
Described collimator zero-bit collecting unit is arranged on the zero-bit position of collimator track by fixed support.Be convenient to arrange, can be arranged on as required on the collimator track, highly, the position is convenient adjusts.
Described collimator zero-bit collecting unit adopts photoswitch.Also can be photoisolator, position signalling be converted to the switching value signal of break-make by optical signal, processes accurately simple.
The beneficial effect that the collimator zero adjustment device of this utility model medical accelerator has is: by the side photo-electric collimator zero-bit collecting unit at the collimator track, the input of processor arranges the outfan that connects collimator zero-bit collecting unit, and as required by the fixed support adjustment, so that can reach the collimator zero-bit of accelerator is carried out accurate calibration, guarantee higher repetitive positioning accuracy.On this basis, can carry out Accurate Position Control by the collimation device, improve radiotherapeutic effect.
Description of drawings
Fig. 1 is this utility model structural representation.
Among the figure: 1, collimator zero-bit collecting unit 2, fixed support 3, processor 4, collimator 5, outfan 6, input.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, collimator zero-bit collecting unit 1 is fixed on the collimator zero-bit position of collimator 4 tracks by collimator zero-bit collecting unit fixed support 2, the outfan 5 of collimator zero-bit collecting unit 1 connects the input of processor 3, and the signal that collimator zero-bit collecting unit 1 gathers is transported to processor 3 inputs 6 from outfan 5 and processes.
Collimator zero-bit collecting unit 1 adopts photoswitch.It also can be photoisolator.
Operation principle and use procedure:
When collimator 4 moves to the zero-bit position in orbit, the zero signal that collimator zero-bit collecting unit 1 collects passes to the input 6 of processor 3 from outfan 5, after processor 3 obtains zero signal, the current location of record and calibration collimator 4 is zero-bit, and with this benchmark zero-bit as collimator 4, carry out motor control.
