Embodiment 1

[0037] See Figure 1 to Figure 4 , figure 1 Shown is a three-dimensional view of Embodiment 1 of the treatment system integrating imaging and radiotherapy of the present invention; figure 2 Shown is a schematic structural diagram of Embodiment 1 of a treatment system integrating imaging and radiotherapy of the present invention; image 3 Shown as figure 2 A-A section view; Figure 4 Shown as figure 2 B-B cross-sectional view.

[0038] The treatment system integrating imaging and radiotherapy includes a radiotherapy device and a nuclear magnetic resonance imaging device arranged on one side of the radiotherapy device.

[0039] The radiotherapy device includes a radiation source supporting device 1 and a radiation source device 2 arranged on the radiation source supporting device 1. The radiation source supporting device supports the radiation source device. The radioactive source device includes several radioactive sources. The radioactive source may be any one of cobalt 60 isot...

Embodiment 2

[0049] See Figure 8-10 , Figure 8 Shown is a perspective view of Embodiment 2 of the treatment system of the present invention; Picture 9 Shown is a schematic structural diagram of Embodiment 2 of the treatment system of the present invention; Picture 10 Shown as Picture 9 D-D section view.

[0050] The difference between this embodiment and the first embodiment is that the radiation source device 2 is driven by a driving mechanism to make an arc-shaped reciprocating movement around the treatment center O point. Picture 10 The arrow in indicates the arc-shaped reciprocating direction of the radiation source device 2. The driving mechanism includes an arc guide rail provided on the radiation source supporting device 1 and a second motor (not shown in the figure) that drives the radiation source device 2 to reciprocate along the arc guide rail.

[0051] The radiation source device 2 is provided with a plurality of radiation sources, and the arrangement direction of the radiatio...

Abstract

The invention relates to a therapy system integrating images and radiotherapy. The system comprises a radiotherapy device. The radiotherapy device comprises a radioactive source device and radioactive source supporting device for supporting the radioactive source device. The therapy system integrating images and radiotherapy is characterized by also comprising a magnetic resonance imaging device arranged at one side of the radiotherapy device; the magnetic resonance imaging device comprises two magnets generating even field and a magnetizer for supporting the magnets; and the therapeutic centre of the radiotherapy device is within the even filed zone between the two magnets. The therapy system integrating images and radiotherapy provided by the invention integrates image diagnosis function and radiotherapy function, thus not only can the image of a focus be seen in real time during radiotherapy to realize more accurate therapy positioning, but also the therapy system has simple structure and convenience in installation.

Description

Technical field [0001] The invention relates to a medical radiotherapy equipment, in particular to a treatment system integrating imaging and radiotherapy. Background technique [0002] Radiotherapy equipment has been widely used for the treatment of tumors and other diseases, but the existing radiotherapy equipment only has a therapeutic function, and the disease needs to be diagnosed or focused on B-ultrasound or CT or Magnetic Resonance Imaging (MRI) equipment in advance (The diseased tissue, such as tumor) is located, and then treated by the treatment equipment according to the diagnosis result. For example, it is necessary to use MRI to locate the focus of the patient first, and then remove the patient and the positioning bed from the magnetic field of the MRI. Among them, the positional relationship between the patient and the positioning bed remains unchanged, and then the patient and the positioning bed are put into the existing radiotherapy device for radiation therapy....
