- the head 54 has an X-ray irradiation port 55 at the tip.
- the X-ray therapy device 51 is controlled by a control device (not shown), and directs the X-ray irradiation port 55 to a patient's lesion.
- X-rays emitted from the X-ray irradiator 55 are generated by irradiating a target such as a tungsten lamp with electrons from an electron gun. Radiation therapy is used for X-ray radiography, etc. An X-ray with a larger output than the line is required. Therefore, in order to obtain high-power X-rays, the radiation therapy equipment uses an accelerating tube that accelerates electrons with micro-waves, and hits the accelerated electrons to the target.
- Microwave sources that supply microwaves include, for example, magnetrons and Klystron forces S. Magnetron is easily used as a micro wave source mounted on the head 54 of the X-ray therapy device 51 because it is easier to miniaturize than a crystaltron. You.

Since the robot arm 53 supporting the head 54 is inevitably robust and large, it is difficult to accurately position the robot arm 53 so that the operation of the robot arm becomes slow. Become.
- Magnetron has a low output of micro-waves. If a small magnetron is used to be mounted on the head section 54, the X-ray therapy apparatus 51 cannot obtain a large output microwave. Therefore, since the X-ray therapy apparatus 51 cannot obtain high-power X-rays, there is a limit to the therapeutic effect on a lesion deep inside the human body.
- the output of the magnetron is unstable because it generates a microwave by self-excited oscillation. Therefore, the output of X-rays also becomes unstable.
- the service life of the magnetron is shorter than that of the crystron, so the head 54 needs to be frequently maintained. Magnetron is less reliable as a device than Krycetron.
- Krystron is not suitable as a microphone mouth wave source to be mounted on the head 54 because the size of the device is larger than that of Magnetron. is there.

If the microphone mouth wave source provided as a power source is arranged at the base of the radiation irradiation device, the head section becomes smaller and lighter, so that the burden on the manipulator is reduced, and the manipulator is reduced. The weight can be reduced.

- the head part 5d is connected to the head part 6 so as to be rotatable with respect to the head mount 5d.
- Each connecting portion incorporates a servo motor (not shown) controlled by the control device S. Therefore, the maupilator 5 can position the head section 6 with respect to the treatment section of the patient P.

- the X-ray generator 8 includes an electron gun 9, a target 10, and an acceleration tube 11 employed as an accelerator.
- the electron gun 9 emits electrons toward the target 10. When an electron hits the target 10, the target 10 emits X-rays from the opposite surface.
- the accelerating tube 11 is disposed between the electron gun 9 and the target 10, and accelerates the electrons emitted from the electron gun 9 toward the target 10 with a micro wave.
- X-rays radiated from the target 10 are emitted from an X-ray irradiation port 15 provided at an end of the head section 6.
- a collimator 14 for restricting X-rays emitted from the X-ray irradiation port 15 is attached to an end of the head portion 6.
- Microwaves used in the accelerating tube 11 are supplied by a microwave source 4 installed at the base of the manipulator 5.
- the microwave oscillated by the above is propagated by the waveguide 12 to the acceleration tube 11 of the head 6.

- the X-ray therapy apparatus 1 includes the control device S at a position away from the cart.
- the control device S controls the servo motors of the manipulator 5 and the truck 3 and the drive device of the truck 3 so that the treatment position can be irradiated with X-rays.
- the X-ray irradiation port 15 of the head 6 is positioned toward the treatment position.
- the control device S operates the micro wave source 4 and the electron gun 9. Electrons emitted from the electron gun 9 are accelerated by the microwave while passing through the acceleration tube 11, and hit the target 10.

In order to irradiate the treatment position with X-rays from multiple directions, the X-ray treatment apparatus 1 moves the head unit 6 around the treatment position set by the control device S. Then, the X-ray therapy apparatus 1 is operated so that the irradiated X-ray passes through the treatment position. X-ray irradiation is repeated by changing the position and angle of probe section 6.
- the X-ray therapy apparatus 1 has the electron gun 9, the target 10, and the acceleration tube 11 mounted on the head 6, the micro-wave source 4, the trans- The power supply and the like were arranged at the base 5a of the manipulator 5. That is, in the X-ray therapy apparatus 1, devices directly related to X-ray generation are mounted on the head unit 6, and other devices are disposed on the base 5a of the manipulator 5. Therefore, the head section 6 is reduced in size and weight. Since the head 6 of the X-ray therapy apparatus 1 is small, when the treatment section of the patient P is treated, restrictions on the movable range of the head 6 are reduced.
- the X-ray therapy device 1 has a reduced weight of the head section 6,
- the manipulators that support it can also be made lighter and simpler. Therefore, the X-ray therapy apparatus 1 can control the operation more promptly and accurately.

Since the X-ray therapy apparatus 1 employs a crystal mouth as the microwave source 4, a microwave mouthwave having a stable output can be obtained. Then, the X-ray therapy apparatus 1 generates X-rays when electrons accelerated by the micro-waves hit the target 10. Since the output of the device is also stable, a highly reliable radiation irradiation device can be obtained. In addition, Crystron has a longer device life than Magnetron, so the operating rate as a radiation irradiation device is improved.
- the cart 3 can move in the X direction along the rail 2, and the tra-on 7 provided in the microphone mouth wave source 4 can rotate in the middle V direction. Since the X-ray therapy apparatus 1 has a degree of freedom in a part other than the manifold 5, the degree of freedom required for the manipulator 5 required for positioning the head unit 6 is determined. The number of degrees of freedom (rotary axes) can be reduced. Since the X-ray therapy apparatus 1 can reduce the number of joints (joints) of the manipulator 5, the bending portion of the waveguide 12 provided along the manipulator 5 can be reduced. It is possible to reduce the number of rotary RF power brass 13 provided in the apparatus. Therefore, the manipulator 5 of the X-ray therapy apparatus 1 is simplified.
- the waveguides 12 are arranged in a bare manner along the manifold 5, but if they are housed in the manifold 5, they are provided. However, the appearance is simplified. In addition, if there is no problem in performing medical treatment on the patient, the bending or rotating portions of the manipulator 5 and the accompanying waveguides 12 are the same as those of the present embodiment. It can be more or less than the thing.
- the power source of the accelerator may be provided in the middle of the manipulator 5.
- the base of the manipulator 5 or the mounting base 3 may be fixed to the floor.
