いうものであった。Conventionally, treatment using a radiation therapy apparatus has been performed as follows. That is, first, X #i! 1. The affected area is discovered and its location confirmed using diagnostic equipment such as an X-ray machine and a convenience store tomography machine. Then, a marking (using paint or the like) indicating the affected area was applied to the patient's body surface, and then the patient was led to a radiotherapy device, and the markings were used to irradiate the patient with therapeutic radiation.
したがって体表面へのマーキングという不正確な要素が

As shown in FIG. 1, a therapeutic radiation irradiation device 1 is held in a gantry 3 so as to be able to irradiate a patient (not shown) lying on a bed device 2 with radiation from any angle. Although not shown in this gantry 3,
A tube, an X-ray detector, and a rotational drive mechanism for rotationally driving these to scan a patient with an X-ray beam are housed, and the irradiation device 1 is detachably connected to this rotational drive mechanism. It has become. The bed device 2 can move the position of its top plate back and forth, left and right, and up and down.

天板を前後方向に少しずらす。Next, explanation will be given with reference to FIG. First, a patient is laid down on the top plate of the bed device 20 and scanned with an X-ray beam. At this time, the input device 13 manually inputs instructions such as the operation mode, the CPU (Central Processing Unit) 11 issues commands, the connection control device 5 is controlled via the gantry interface 4, and the irradiation device 1 is rotated by the rotation drive mechanism. At the same time, the rotating part a mechanism is rotated by the scanning control device [7 to perform scanning with the X-ray beam. In this way, data regarding the X9 intensity transmitted through the patient is obtained, and after this data is digitized by the AD converter 9, it is sent to the image reconstruction device 10. This image reconstruction device 10
Then, a tomographic image of a slice plane (tomographic plane) of a patient scanned with an XN beam is reconstructed by processing the above data. Under the control of the CPU II, this tomographic image is output by an output device 12 such as a CRT display device and is also stored in an auxiliary storage device 14. When one tomographic image is obtained in this way, the bed control device 6 controls the bed device 2,
Move the top plate slightly forward and backward.

に得られ、患部の立体的な形状が把握できる。In this way, the slice plane is slightly shifted, and a tomographic image of this slice plane is obtained in the same way. By scanning the X-ray beam while shifting the bed top little by little in this way, tomographic images of many adjacent slice planes near the affected area can be obtained one after another, making it possible to understand the three-dimensional shape of the affected area. .

An irradiation device 1 is connected to a rotational drive mechanism. Then, the bed control device 6 controls the ped device [12], and the patient is moved to a position where the affected area is irradiated with radiation.

Further, the rotation drive mechanism is controlled by the scanning control device 7, and the irradiation device 1 rotates while irradiating radiation, so that the affected area can be irradiated with radiation from various angles. All such controls, such as positioning of the affected area to be irradiated and the irradiation angle, are performed under the control of the CPU 11 based on the aforementioned tomographic image data.

備える場合より、スペース的及び経済的に有利である。As described above with respect to the embodiments, according to the present invention,
The combinator tomography device and the radiation therapy device are combined with some mechanisms in common. First, the computer tomography device obtains diagnostic data, and based on this data, radiation therapy such as positioning of the area to be irradiated is performed. Since the irradiation device is controlled, diagnostic data can be directly used as control data for radiation irradiation without marking the patient's body surface, making it possible to perform treatment with accurate radiation irradiation and improve diagnosis. , a series of treatment operations can be efficiently performed without moving the patient (the patient does not need to move from the combinator tomography device to the treatment device, but only needs to lie on the bed device). Also, because it is mechanically shared,
This is more advantageous in terms of space and economy than the case where the combination tomographic imaging device and radiation therapy device are provided separately.
