Problems solved by technology

It can be seen that the existing radiation therapy device and treatment method need to move the patient twice and perform two positioning, so the positioning system required is relatively complicated and the positioning time is relatively long
Moreover, during the treatment process, since there is no imaging device with imaging function, it is difficult to realize real-time image monitoring and real-time treatment.

Embodiment 1

[0026] See Figure 1-3 , figure 1 Shown is a three-dimensional schematic diagram of Embodiment 1 of a treatment system integrating imaging and radiotherapy according to the present invention; figure 2 Shown is a structural schematic diagram of embodiment 1 of the treatment system integrating imaging and radiotherapy according to the present invention; image 3 shown as figure 2 A-A cutaway view. This treatment system integrating imaging and radiation therapy includes a radiation therapy device, which includes a radiation source device 2 with multiple radiation sources and a radiation source support device 1 for arranging the radiation source device 2 The treatment system integrating imaging and radiation therapy also includes a nuclear magnetic resonance imaging device, the nuclear magnetic resonance imaging device includes a first magnetic pole 4 and a second magnetic pole 5 for generating a shimming area and for supporting the The magnetizer 3 of the first magnetic pol...

Embodiment 2

[0032] See Figure 4-5 , Figure 4 Shown is a schematic structural view of Embodiment 2 of a treatment system integrating imaging and radiotherapy according to the present invention; Figure 5 shown as Figure 4 The B-B section view. The difference between this embodiment and Embodiment 1 lies in that the structure of the motion mechanism for driving the radiation source device 2 to rotate around the treatment center O is different.

[0033] The radiation source device 2 is driven by the movement mechanism to reciprocate in an arc around the treatment center O. Figure 5 The middle arrow indicates the arc-shaped reciprocating direction of the radiation source device 2 .

[0034] The moving mechanism includes an arc-shaped guide rail fixed on the radiation source supporting device 1 and a second motor (not shown) for driving the radiation source device 2 to reciprocate along the arc-shaped guide rail.

[0035] The radiation source device 2 is provided with several radiatio...

Abstract

The invention discloses a therapy system integrating imaging with radiotherapy, which comprises a radiotherapeutic unit and a nuclear magnetic resonance imaging unit, wherein the radiotherapeutic unit comprises a radioactive source unit and a radioactive source support device, the radioactive source unit is mounted on the radioactive source support device, the nuclear magnetic resonance imaging unit comprises a first magnetic pole, a second magnetic pole and a magnetic conductor, the first magnetic pole and the second magnetic pole are used for generating a shimming region, the magnetic conductor is used for supporting the first magnetic pole and the second magnetic pole, the radioactive source unit and the radioactive source support device are arranged on one side of the first magnetic pole or the second magnetic pole, and are connected with the magnetic conductor through a moving mechanism, and the radioactive source rays of the radioactive source unit run through the nearer magnetic pole and are focused at a therapeutic center positioned in the shimming region generated between the first magnetic pole and the second magnetic pole. Since the therapy system integrates the functions of image diagnosis and radiotherapy, the image of a focus can be seen in real time during radiotherapy, consequently, the treatment is more accurate, and the effect is better; and moreover, the therapy system has a simple structure, and is convenient to mount.

Description

technical field [0001] The invention relates to a medical treatment system, in particular to a treatment system integrating imaging and radiotherapy. Background technique [0002] Existing radiation therapy systems only have a therapeutic function. Before treatment, it is first necessary to use MRI (Magnetic Resonance Imaging, that is, nuclear magnetic resonance imaging device) to determine the location of the lesion (lesion tissue, such as a tumor), and then move the patient and the positioning bed out of the magnetic field of the MRI. The positional relationship of the bed remains unchanged, and then the patient and the positioning bed are put into the existing radiotherapy device for radiation therapy. At this time, the positioning bed needs to be repositioned. It can be seen that the existing radiation therapy device and treatment method need to move the patient twice and perform two positionings. Therefore, the required positioning system is relatively complicated and ...
