Abstract
The directional strengthen regulating radiotherapeutic apparatus includes shielding and protecting assembly, focusing units, strengthen regulating board and driving mechanism. The advantage of the present invention is that the independently rotated and focused units may be laid in different angles to focus the dispersive rays, such as gamma rays, onto the disease focus, so that the disease focus obtains high energy irradiation while the health tissue obtains very lower irradiation, reaching stereo directional treatment. By means of the control of the switches and speeds of the focusing units and the strengthen regulating board, the spatial distribution of the dosage absorbed by the disease focus is regulated and the important tissue of the patient may be protected by means of the independent switching function.
Description
Technical field
The present invention relates to the armarium technical field, specifically a kind of directed Intensity Modulation Radiated Therapy (IMRT) device.
Background technology
Present existing accent intensity device, as: dynamic multi-leaf optical grating need be used with clinac.If need carry out stereotactic irradiation, need or use special stereo directional radiotherapy apparatus at the additional stereotaxis isocentric gantry (being commonly called as the X cutter) of clinac, as the γ cutter, but the latter can not carry out conformal intensity modulated treatment.Equipment investment is big like this, and operation and use are complicated.
Summary of the invention
It is low to the objective of the invention is to design a kind of price, is easy to popularize, and has stereotactic radiotherapy, can also transfer strong radiotherapy unit.
The directed Intensity Modulation Radiated Therapy (IMRT) device of the present invention, comprising: the shielding protection assembly, at least two focusing bodies that can independently rotate are transferred strong plate, actuating device.
The shielding protection assembly comprises: shield and shield door.
The focusing body of independent rotation comprises: radioactive source carrier, ray collimation body rotate around axis, and link to each other with shield, and two radioactive sources are housed on the radioactive source carrier at least, on radioactive source carrier, the ray collimation body gear are housed all.Focus on body and link to each other with shield by different angles, on the ray collimation body tungsten alloy shield plug is housed in the space.
The focusing body of independent rotation distributes by different angles in the space, and their ray spatially collects in a bit (focus).
Actuating device comprises: the multilamellar sleeve links to each other with power, and gear all is housed on two sleeves, and interior axle links to each other with the strong plate of accent.
The advantage of the directed Intensity Modulation Radiated Therapy (IMRT) device of the present invention is: adopt in the space and arrange the focusing body that can independently rotate by different angles, and focus on body with each dispersive radioactive source such as gamma ray focusing on focus, thereby make focus obtain very high-energy source irradiation, normal structure only is subjected to very little irradiation, reaches the function of stereotactic irradiation.By controlling switch and the velocity variations that each focuses on body and transfers strong plate, the dosage that changes the focal zone absorption reaches in spatial distributions transfers potent fruit, can utilize simultaneously to focus on body or transfer the independent switch function of strong plate that patient's vital tissue is protected.

The specific embodiment
According to Fig. 1-shown in Figure 3, on the radioactive source carrier 7 gear is housed, on the ray collimation body 8 gear is housed, the tungsten alloy shield plug is housed simultaneously, radioactive source carrier 7, ray collimation body 8 are around axis 14 rotations, they all link to each other with shield 15, then form focusing body 1, focus on body 1 and be contained on the shield 15 by at least two of different angles in the space, interior axle 11 links to each other with the strong plate 2 of accent, on the interior sleeve 13 gear is housed, the gear that this gear and ray collimation bulk phase connect is meshed; On the outer sleeve 12 gear is housed, the gear on this gear and the radioactive source carrier 7 is meshed.Shield 15 links to each other with shield door 4,16, and interior axle 11, outer sleeve 12, interior sleeve 13 link to each other with power.
The directed Intensity Modulation Radiated Therapy (IMRT) device of the present invention radiotherapy is achieved in that patient is placed on the therapeutic bed, make focus with 3 D positioning equipment, the shield door 4,16 of the Intensity Modulation Radiated Therapy (IMRT) device of therapeutic bed top is opened, the ray that focuses on body 1 is all concentrated on patient's focus.
When needs change the dosage of focus, rotate one or several ray that focuses on body 1 collimation body 8 by the machine driving driven gear, make it be in masked state, ray is blocked by the tungsten alloy shield plug on the ray collimation body, thereby reaches the dosage that changes focus.
Transfer strong plate 2 to be used for the adjustment of irradiation field intensity and the protection of sensitive organization.Intensity modulated is by closing some or several focusing bodies and change transferring the rotary speed of strong plate 2 to realize by mechanical driving device, transfers strong plate 2 to be made by tungsten alloy, has some holes above, so that the angle that control is blocked.When needing protection sensitive organization, make the strong plate 2 of accent be parked in a certain position by mechanical driving device, block ray and pass sensitive organization, make patient obtain good curing like this.
