Abstract
The present invention relates to radiation treatment equipment with a radiation treatment module. The radiation treatment module comprises a cantilever. The treatment ray can irradiate from the cantilever to an object to be irradiated and furthermore the cantilever is fixed on a movement control device that the cantilever can rotate around a central point. Thus the treatment ray can irradiate to an isocenter point from different angles. Besides, the radiation treatment module comprises at least one X-ray imaging module with an X-ray source and an X-ray detector. The X-ray source is movably configured on a first frame which is above the cantilever and is parallel with ground. The X-ray detector is movably configured on a second below an object. Thus, the X-ray source and the X-ray detector can be moved randomly along the first frame or the second frame through an advantageous mode and are positioned for X-ray imaging photography.
Description
Technical field
The present invention relates to a kind of radiotherapy equipment that has therapeutic radiation treatment module and at least one diagnostic x-ray imaging module.This type of radiotherapy equipment is mainly used in the processing tumor.
Background technology
The tissue that uses radiation to destroy pathological changes is a widely used method in the radiological medicine.Used the equipment that utilizes high-energy electromagnetic radiation (X-radiation, gamma radiation) or particle radiation (electronics, proton, carbon ion) for this reason.The radiation of in radiotherapy, using typically is positioned at the energy range of megavolt (MV).In radiocurable process, require accurately to make body region to be illuminated tumor particularly to be illuminated receive sufficiently high radiation dose with assurance in the location, but damage patient's health tissues simultaneously as few as possible the patient.For positioning, during handling, in the time period of rule, carry out location usually to the intravital body region to be illuminated of patient.This usually uses the radiation in kilovolt (kV) energy range to carry out through the x-ray imaging method, carries out through computer tomography especially.For avoiding patient's location of mistake, this type of inspection is preferably directly carried out on radiation position.
Use is important from the radiating radiation treatment of different directions, makes the ray that is used for each direction all arrive tumor.Ray should intersect at a some place that is positioned at tissue in area to be illuminated.This point is called isocenter point and has represented the intersection point corresponding to the ray of different irradiation position.
Known radiotherapy equipment is described in document US 2005/0085710A1; This radiotherapy equipment has therapeutic radiographic source and two diagnostic x-ray imaging modules that fixed-site ground is installed, and each has x-ray source and X-ray detector said x-ray imaging module.Fig. 1 shows this radiotherapy equipment 1; Said radiotherapy equipment 1 comprises the radiotherapy module that has the cantilever 3 that is arranged on the robot 2; On said cantilever 3, rotatably arranged radiographic source 4; Linear accelerator for example, to be used to send the therapeutic treatment ray, said therapeutic treatment ray arrives during handling on one's body the unshowned patient who is bearing on the patient table 5.Radiotherapy equipment 1 is fixed on two X-ray detectors that two x-ray sources 6 handling on the spatial ceiling and same fixed-site ground are put based on floor cloth with comprising fixed-site in addition.
Promptly there is not the risk of x-ray imaging parts 6,7 and 4 collisions of movable treatment radiographic source in the advantage of the radiotherapy equipment of the diagnostic x-ray imaging module of installing as shown in Fig. 1 with having fixed-site.In addition, cancelled integrated with the costliness of x-ray imaging parts 6,7 in the radiotherapy module.Shortcoming is x-ray imaging parts 6,7 no movable property.In addition, x-ray imaging parts 6,7 possibly be positioned at the ray stroke of therapeutic treatment ray, have therefore shortened the life-span of the sensitive electronic devices of x-ray imaging parts 6,7.Also possibly make treatment radiographic source 4 limit the ray stroke of x-ray imaging parts 6,7.
Summary of the invention
Technical problem to be solved by this invention is the other structural form that provides the radiotherapy equipment that has at least one x-ray imaging parts.
The present invention requires to protect a kind of radiotherapy equipment that has the radiotherapy module; Said radiotherapy module comprises cantilever; The therapeutic treatment ray can point to object and said cantilever to be illuminated from said cantilever and be fixed on the motion control device in this wise; Make cantilever with this therapeutic treatment ray can be pointed to isocenter point from different angles around the isocenter point rotation.In addition, the radiotherapy module comprises that at least one has the x-ray imaging module of x-ray source and X-ray detector.X-ray source is arranged in movingly and is arranged in rigidly on cantilever first pedestal top, parallel with the floor.X-ray detector is arranged on second pedestal that is arranged in the object below rigidly movingly.With this, can make x-ray source and X-ray detector through favourable mode at random along first pedestal or second pedestal moves and locate for realizing that x-ray imaging is taken.
In other form of implementation, x-ray source and X-ray detector be positioned opposite in this wise, the feasible diagnostic x-ray imaging that can carry out object from different directions.
In other form of implementation, first pedestal can be arranged and be connected on the ceiling or on the sidewall.Can realize the flexible installation of first pedestal with this.
In other structure of the present invention, second pedestal can be integrated in the floor or be arranged on the floor.
In addition, but first pedestal can comprise first track of x-ray source move inside.In addition, but second pedestal can comprise second track of x-ray source move inside.Through the mobility and the turning property of x-ray source and X-ray detector, assurance can be carried out the diagnostic x-ray imaging of object from different directions.
Description of drawings
Further characteristics and advantages of the present invention from following basis schematically show for visible the explanation of embodiment.
Each figure is:
Fig. 1 show according to the radiotherapy equipment that has the x-ray imaging module of installing on fixed-site ground of prior art and
Fig. 2 shows the radiotherapy equipment of the pedestal that has two fixed-site, and said pedestal has the mobile x-ray image-forming module.
The specific embodiment
The radiotherapy equipment of the pedestal that has two fixed-site has been shown in Fig. 2, and said pedestal has the mobile x-ray image-forming module.Radiotherapy equipment 1 comprises the radiotherapy module that has cantilever 3; (sightless at this) radiographic source and the chip collimator (Lamellen-Kollimator) that are used for (sightless at this) therapeutic treatment ray are positioned at cantilever 3 at least in part, and said processing ray arrives during handling on one's body the patient 8 who is bearing on the patient table 5.Cantilever 3 is fixed on the motion control device in this wise, makes cantilever 3 with this therapeutic treatment ray can be pointed to isocenter point from different angles around the isocenter point rotation.First pedestal 9 is parallel to the floor 10 of the process chamber that radiotherapy equipment 1 is placed in and is arranged in the top of cantilever 3 rigidly.Second pedestal 11 is integrated in the floor below patient 8 rigidly.Radiotherapy equipment 1 comprises the first x-ray imaging module of being made up of first x-ray source 12 and first X-ray detector 13, and the second x-ray imaging module of being made up of second x-ray source 14 and second X-ray detector 15.First and second x-ray sources 12,14 are arranged on first pedestal 9 movingly, and first and second X-ray detectors 13,15 are arranged on second pedestal 11 movingly.For example, they can move on unshowned track, and can be reversed.The movable property of the parts 12,13,14,15 through two x-ray imaging modules makes it possible to carry out the diagnostic x-ray imaging for patient 8 from different directions.In Fig. 2, the first x-ray imaging module that has x-ray imaging parts 12,13 is illustrated at two different position I and I ', and the second x-ray imaging module that has x-ray imaging parts 14,15 is also illustrated at two different position II and II '.
