Problems solved by technology

[0003] In order to overcome the problems existing in the prior art that the thickness of the collimator is the same for head treatment and body treatment, there is no difference in focusing accuracy, the treatment effect of the whole machine is poor, there are many blind spots, and the replacement of the collimator must be done manually, and the replacement cycle Long, complex operation, greater radiation to people, and certain dangerous deficiencies, the present invention proposes a whole-body Gamma Knife collimator

Embodiment 1

[0028] This embodiment is a whole-body Gamma Knife collimator, including a head collimator and a body collimator, which are used for head treatment and body treatment respectively. The collimator material is W95, the density is greater than or equal to 17.8g / cm 3 , can shield radiation when not performing treatment. The inner and outer surfaces of the head collimator and the body collimator are spherical. In this embodiment, the outer spherical radius of the head collimator and the body collimator are both 390mm; the inner diameter of the body collimator is 310mm, and the inner diameter of the head collimator is 210mm, so as to meet the treatment space requirements of the head and body s difference.

[0029] Such as Figure 9 , Figure 10 As shown, the head collimator fixing frame 11 and the body collimating body fixing frame 9 are parallel to each other, fixedly installed on one side of the frame 8, and perpendicular to the frame. The head collimator 7 and the body colli...

Embodiment 2

[0034] This embodiment is a whole-body Gamma Knife collimator, including a head collimator and a body collimator, which are used for head treatment and body treatment respectively. The collimator material is W95, the density is greater than or equal to 17.8g / cm3 , can shield radiation when not performing treatment. The inner and outer surfaces of the head collimator and the body collimator are spherical. In this embodiment, the outer spherical radius of the head collimator and body collimator is 430mm; the inner diameter of the body collimator is 350mm, and the inner diameter of the head collimator is 250mm. different.

[0035] Such as Figure 9 , Figure 10 As shown, the head collimator fixing frame 11 and the body collimating body fixing frame 9 are parallel to each other, fixedly installed on one side of the frame 8, and perpendicular to the frame. The head collimator 7 and the body collimator 4 are respectively fixed on the head collimator fixture 11 and the body colli...

Abstract

The invention discloses a whole body gamma knife alignment body, which comprises a head alignment body (7) and a body alignment body (4). The outer diameter of the head alignment body is same as that of the body alignment body; the inner diameter of the head alignment body (7) is 210 to 250mm, and the inner diameter of the body alignment body (4) is 310 to 350mm; the intrados of the head alignment body and the body alignment body are opposite and the center lines of the head alignment body and the body alignment body are overlapped; a target A of the head alignment body is overlapped with a target A' of the body alignment body, namely the ball centers (6) of the head alignment body and the body alignment body are overlapped; the ball centers are overlapped with a rotary center line (10) of a frame; and a head alignment body fixing frame (11) and a body alignment body fixing frame (9) are parallel to the rotary center line (10) of the frame. The whole body gamma knife alignment body has the characteristics of simple structure, small occupied space, wide treatment range, high accuracy, safety and reliability, and convenient maintenance, and can accurately meet the requirements on target size and dosage during treatment of the head and body.

Description

1. Technical field [0001] The invention relates to the field of medical radiation, in particular to a whole-body gamma knife collimator. 2. Technical Background [0002] The existing medical gamma knife is divided into head gamma knife and body gamma knife. Among them, the head gamma knife can only treat the head, while the body gamma knife can only treat the body except the head. Therefore, if a hospital wants to treat both the head and the body of the patient, it often needs to purchase the gamma knife for the head and the gamma knife for the body at the same time, and the gamma knife for the head Both the knife and the body gamma knife are very expensive, especially the head gamma knife is extremely expensive. Many hospitals only buy the body gamma knife, but cannot treat the head of the patient. Although a company produces a whole-body gamma knife, the replacement of the collimator must be done manually. The replacement cycle is long, the operation is complicated, and t...
