Abstract
The utility model relates to a radiotherapy apparatus which comprises a source body, a roller, a driving mechanism, a therapy bed and a control system, wherein the source body which is installed in the roller moves around a focal point (O) on an axle wire of the roller under the action of the driving mechanism, and the inner part of the roller is also provided with a scanning and imaging apparatus for carrying out real-time detection on the positions of tumors in the process of radiotherapy. Since the real-time scanning and imaging apparatus is added in the roller, the positions of the tumors can be detected in real time, and the therapy bed can be adjusted so as to ensure the position of a human tumor to be always at the position of the focal point through the real-time detection of the scanning and imaging apparatus on the positions of the tumors, so that the purpose of monitoring the precision of treatment in real time in the course of treatment is achieved.
Description
Technical field
This utility model relates to radiotherapy apparatus.

Summary of the invention
To be solved in the utility model is existing radiotherapy apparatus can not detect the real time position of tumor in therapeutic process technical problem.
In order to solve above technical problem, the technical scheme that this utility model is taked is:
A kind of novel radiotherapy apparatus, comprise source body, cylinder, driving mechanism, therapeutic bed and control system, the source body is installed in the cylinder, in focus (O) motion of source body under the effect of driving mechanism on the cylinder axis, it is characterized in that, also be provided with the scanned imagery device that is used for detecting in real time knub position in the cylinder at radiation therapy process.
Comprise that also one is equipped with the support of bearing, fixedly connected with inner wall of rotary drum in the two ends of support, the axis of bearing and the axis of described cylinder are vertically intersected on described focus (O), the internal ring of described bearing is connected with an internal ring driving mechanism, described source body is arranged on the internal ring, the lonizing radiation that the intravital radioactive source in source launches radioactive source under the effect of collimator focus on described focus (O), and described scanned imagery device is CT or MRI or SPECT.
Described source body is fixedlyed connected with cylinder, and described driving mechanism is by the head roll swing or rotate focus (O) swing or the rotation of drive source body on the cylinder axis, and described scanned imagery device is CT or MRI or SPECT.
Described source body is connected by ring-like guide rail guide rail with cylinder, and described driving mechanism is connected with the source body to drive focus (O) swing or the rotation of source body on the cylinder axis, and described scanned imagery device is CT or MRI or SPECT.
Described control system also detects knub position in real time by scanned imagery device and adjusts therapeutic bed so that the human tumor position is in focus (O) position all the time.
Described scanned imagery device comprises the detector that the flying spot source is relative with the flying spot source.
Formed the described focus of process of the radiographic source of described scanned imagery device (O).
After having adopted technique scheme, but owing to be increased in the cylinder real time scan imaging device, not only can detect knub position in real time, and can detect knub position adjustment therapeutic bed in real time so that the human tumor position is in the place, focal position all the time by scanned imagery device, scanned imagery device detects knub position in real time and demonstrates knub position in real time and adjust therapeutic bed so that the human tumor position is in the place, focal position all the time with real-time detected knub position signal input control system and by control system by display, reach in the therapeutic process purpose of monitor treatment precision in real time, as the people when breathing therapeutic bed thereupon reserve motion to guarantee the treatment precision.
Description of drawings
Fig. 1 is a longitudinal cross-section of the present utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of novel radiotherapy apparatus, comprise source body 1, cylinder 2, driving mechanism, therapeutic bed and control system, comprise also in the cylinder 2 that one is equipped with the support 3 of bearing, fixedly connected with cylinder 2 inwalls in the two ends of support 3, the axis of the axis of bearing and described cylinder 2 is vertically intersected on described focus (O), the internal ring of bearing is connected with an internal ring driving mechanism, source body 1 is arranged on the internal ring, the lonizing radiation that radioactive source in the source body 1 launches radioactive source under the effect of collimator focus on described focus (O), also be provided with the scanned imagery device that is used for detecting in real time knub position in the cylinder 2 at radiation therapy process, retouching imaging device is CT or MRI or SPECT, and the scanned imagery device control system also detects knub position in real time by scanned imagery device and adjusts therapeutic bed so that the human tumor position is in focus (O) position all the time.Scanned imagery device comprises the detector 5 that flying spot source 4 and flying spot source 4 are relative, flying spot source 4 with can be with gamma-ray source or x-ray source.
In said structure, can also not need to be provided with support 3 and directly source body 1 be fixedlyed connected with cylinder 2 with bearing, driving mechanism is by head roll 2 swings or rotate focus (O) swing or the rotation of drive source body 1 on cylinder 2 axis; Perhaps source body 1 is connected by ring-like guide rail guide rail with cylinder 2, and driving mechanism is connected with source body 1 source body 1 to drive the focus (O) of source body 1 on cylinder 2 axis to be swung or rotate.Scanned imagery device can be CT or MRI or SPECT, can also be installed in the source body 1 with radioactive source under these two kinds of situations, even can shared radioactive source.Formed of the radiographic source of scanned imagery device is through overfocus (O).
The treatment step is:
1, patient lies in scannings such as making CT or MRI on the therapeutic bed, and scanogram is transferred to the TPS work station, and the doctor makes the TPS treatment plan.
2, the treatment plan after the doctor will examine passes to the gamma knife treatment system, waits for patient.
3, after patient lay in and enters into the gamma knife treatment system on the therapeutic bed, system entered init state automatically, carries out initialization.
