Abstract
The present invention specially relates to a kind of therapeutic apparatus which utilizes accelerator to produce radioactive ray used for therapy of whole body. Said therapeutic apparatus consists of therapeutic head and its moving rack, which consists of serially connected vertical telescopic mechanism, vertical rotary mechanism, horizontal moving guiding mechanism and horizontally fixed guiding mechanism. Said invention features simple structure, high positioning accuracy, convenient for controlling and capable of arbitrarily regulating the scanning track of the radioactive ray of the therapeutic head in accordance with the therapeutic demand.
Description
The present invention proposes a kind of stereo directional radiotherapy apparatus, relates to medical radiotherapy equipment, and the lonizing radiation that particularly utilize accelerator to produce act on the therapy equipment of human body whole body.
Background technology of the present invention is to utilize the therapy equipment to the human lesion irradiated tissue of scanning focused electron beam or X ray.Existing medical stereo directional radiotherapy apparatus, for example the X knife system generally is the plane machinery rotation and the rotation of therapeutic bed around the different deflection angles of isocenter point that utilizes accelerator treatment head, the area of lonizing radiation scanning is very limited in the therapeutic process.United States Patent (USP) 5267294 discloses a kind of technology that makes the lonizing radiation directional focusing, it is to utilize electromagnetic focus apparatus that lonizing radiation are deflected on the plane to be mapped to public focus, the support of electromagnetic focus apparatus is made circular motion around isocenter point, thereby realize stereotactic radiotherapy.There are problems such as structure is huge, debugging is complicated, the line speckle is big in this device.
The purpose of this invention is to provide the stereo directional radiotherapy apparatus that a kind of structure is light and handy, control is convenient, be applicable to the human body whole body, can make lonizing radiation above focus point horizontal plane with arbitrarily angled irradiated lesion, with improve burnt skin than and positioning accuracy.
For achieving the above object, therapy equipment of the present invention comprises treatment head and motion frame thereof, and the motion frame comprises vertical telescoping mechanism, vertical slew gear that order joins, moves horizontally guiding mechanism and horizontal fixed guiding mechanism.
The technical scheme that the present invention proposes is simple in structure, the positioning accuracy height, and when the source focal length was 1000mm, the focal position error was less than SR0.1mm, and control is convenient, and the lonizing radiation track while scan can be adjusted arbitrarily as required.
The present invention is further detailed explanation below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of embodiment of the invention X cutter;
Fig. 2 is the control block diagram of embodiment of the invention X cutter;
With reference to Fig. 1, the therapy equipment of X cutter comprises treatment head (6) and a motion frame thereof, and the motion frame comprises the vertical telescopic arm (5), the vertical revoliving arm (4) that are linked in sequence, moves horizontally guide rail (2) and slide block (3), horizontal fixed guide rail (1) and slide block; Treatment head (6) is connected with vertical telescopic arm (5), and treatment head (6) comprises accelerator, target and collimator, produces the required lonizing radiation of treatment.Moving horizontally guide rail (2) moves as directions X along horizontal guide rail (1) by slide block, vertical revoliving arm (4) is made Y to moving by slide block (3) along moving horizontally guide rail (2), vertical in addition telescopic arm (5) along vertical axis Z to moving up and down, thereby make treatment head (6) can reach spatial any point in the range of movement, rotation by vertical revoliving arm (4) and treatment head (6) are around swing of horizontal axis, can adjust treatment head (6) lonizing radiation direction, lonizing radiation are accurately shone on the focus.Treatment head (6) adopts an X-band accelerator, and is in light weight, distortion is little, and by each motion of mechanism of computer control, control is convenient.Can carry out conformal therapy in addition, promptly, focal zone be advanced real shape radiotherapy from different angles by the motion of treatment head (6).Present embodiment adopts the suspension type frame can improve the utilization rate of activity space, moving both vertically of Z direction adopts ball-screw to drive, because the effect of helical angle, but as long as just lock-bit Z is to motion for less moment of torsion, the servomotor that is used to drive has the function of cutting off self-lock.When the center of gravity of treatment head (6) overlaps with the intersection point of the axis of vertical revoliving arm (4) and treatment head (6) horizontal axis, treatment head (6) is except that around the rotation of vertical axis, inertia on other direction of motion is invariable, and the gravity additional load is constant, therefore is easy to realize the accurate continuous path control of treatment head (6).
Shown in Figure 2, be the control block diagram of embodiment of the invention X cutter therapy system, comprise real-time positioning system, it is used to follow the tracks of the motion of focus, and the accurate position of focus is provided to main control computer; Main control computer is used to command and coordinate the function of each subsystem, monitors the state of each subsystem, and the motion of head and motion frame thereof is treated in the instruction and data control that servo-control system is sent according to main control computer.In therapeutic process; the treatment planning system is treated the space motion path of head when main control computer provides when the focus transfixion; main control computer is modified to dynamic trajectory according to the focus real time position that navigation system provides with the static exercise track; give servo-control system with revised transfer of data then; servo-control system moving or rotating according to each mechanism in these Data Control motion frames; main control computer monitors whether whole key link (comprising by the source) is normal when carrying out above task, as notes abnormalities and then send the emergency shutdown instruction.
