Radiotherapy system aligner library device

Abstract

The invention relates to a collimation body warehouse (24) device for radioactive therapy system, which comprises a base (1), a fixing support frame (2), a collimation body warehouse (24), a plurality of collimation bodies (25) which are distributed inside the collimation body warehouse (24), a moving device of the collimation body warehouse (24) which is arranged on the base (1), and a driving device of the collimation body (25) which is arranged on the fixing support frame (2), wherein the moving device of the collimation body warehouse (24) is connected with the collimation body warehouse (24), and the driving device of the collimation body (25) is separately connected with the collimation body in contact joint form. Because the moving device of the collimation body warehouse (24) and the driving device of the collimation body (25) are respectively arranged on the base (1) and the fixing support frame (2), the selection and horizontal driving of the collimation body are performed separately, thus achieving changing the required collimation body from the side face of a host computer 3, reducing the height and volume of the device, reducing weight for convenient maintenance of the device, and carrying out the processing of emergent conditions during treating.

Description

technical field [0001] The invention relates to a radiotherapy system, in particular to a collimated body library device of the radiotherapy system. Background technique [0002] At present, radiation therapy adopts the working principle of rotating focus to rotate and irradiate the patient's lesion, and optimize the treatment plan according to the shape and position of the lesion in the patient's body, and select radiation beams with different diameters to meet the requirements of conformal therapy; During the treatment process, according to the treatment plan, by changing the collimator of different specifications, the diameter of the radiation beam is changed, so as to form focus targets with different focus sizes, so that the lesion tissue at the rotating focus point receives the maximum dose of conformal irradiation, Healthy tissue is irradiated with instantaneous and tolerated dose, so as to kill the lesion, protect the healthy tissue around the lesion, and achieve the...

Problems solved by technology

Chinese Patent Publication No. CN 1569275A discloses a collimation body library device for radiotherapy equipment. The column of the device is equipped with a beam so that the beam is located above the main frame. The outer surface of the body mechanism is equipped with a collimator lifting mechanism, and the column below the beam is equipped with a storehouse for collimators of different specifications. The collimator selection mechanism and the collimator lifting mechanism can move horizontally along the large guide rail of the beam. Select the collimator in the collimator storage and load it into the host from the top of the host, so the longitudinal height of the device is greater than the height of the host, the structure is huge, the design is complicated, and it is not easy to install and maintain
