Problems solved by technology

see instead figure 2 As shown, according to the average height of the doctor, the height of the bed surface of the treatment bed will usually be close to the height of the doctor's armpit, so it will be very difficult to adjust the bed surface of the treatment bed
Adjusting the angle will be particularly difficult for obese patient bodies

Embodiment approach 1

[0049] The first embodiment of the present invention provides a laser positioning system for radiotherapy, which is installed in a treatment room provided with an accelerator 1, and includes an aiming laser positioning module and an auxiliary laser positioning module;

[0050] Wherein, the laser emitted by the aiming laser positioning module is used to locate the irradiation area of ​​the accelerator 1;

[0051]The auxiliary laser positioning module is used to assist in positioning the setting area of ​​the bed surface 5 of the treatment bed.

[0052] Specifically, in this embodiment, see image 3 , Figure 4 As shown, the aiming laser positioning module includes:

[0053] At least two vertical axis aiming and positioning lasers 2 and at least one horizontal aiming and positioning laser 3, the laser light emitted by the longitudinal axis aiming and positioning laser 2 intersects in the irradiation area of ​​the accelerator 1 and forms an intersection line. The quasicenter o...

Embodiment approach 2

[0066] The second embodiment of the present invention provides a laser positioning system for radiotherapy, the second embodiment is a further improvement of the first embodiment; the main improvement is that, in the second embodiment of the present invention, see Figure 6 As shown, there are two auxiliary positioning lasers 4, and these two auxiliary positioning lasers 4 are arranged opposite to each other.

[0067] The use of two auxiliary positioning lasers 4 oppositely arranged can prevent the influence of personnel and equipment from being blocked during operation, and improve the convenience of use of the system.

[0068] It is worth mentioning that, in this embodiment, the horizontal aiming and positioning laser 3 and one of the longitudinal axis aiming and positioning lasers 2 are arranged together along the height direction, so that the positioning and alignment of the laser light can be facilitated.

[0069] Moreover, in this embodiment, there are two horizontal ali...

Embodiment approach 3

[0073] The third embodiment of the present invention provides a laser positioning system for radiotherapy, the third embodiment is a further improvement of the first or second embodiment; the main improvement is that in the third embodiment of the present invention Among them, the colors of the lasers emitted by the horizontal alignment positioning laser 3 and the auxiliary positioning laser 4 are different.

[0074] Different colors can facilitate identification of the laser, and the intersection of the z-axis 6 and the laser emitted by the auxiliary positioning laser 4 can be seen more clearly, thereby facilitating positioning.

Abstract

The invention relates to the field of medical apparatus and instruments, and discloses a laser positioning system and a laser positioning method used for radiation therapy. The laser positioning system is mounted in a treatment room provided with an accelerator, and comprises a collimating laser positioning module and an auxiliary laser positioning module, wherein laser emitted by the collimating laser positioning module is used for locating an irradiation area of the accelerator; the auxiliary laser positioning module is used for carrying out auxiliary positioning on a positioning area. The laser positioning method comprises the following steps: moving a bed surface of a treatment bed to the positioning area; by virtue of the collimating laser positioning module and the auxiliary laser positioning module, adjusting the position of the bed surface of the treatment bed in the horizontal direction and the angle of the bed surface of the treatment bed relative to the horizontal plane, thus completing positioning; and by virtue of the collimating laser positioning module, translating the bed surface of the treatment bed to the irradiation area. With the system adopting the positioning method, the angle of the bed surface of the treatment bed can be easily adjusted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a laser positioning system and a positioning method for radiotherapy. Background technique [0002] Radiation therapy, or comprehensive therapy based on radiation therapy, is the most common and preferred treatment plan for tumor treatment in the medical field today. [0003] Radiation therapy is available for many types of cancer. During treatment, it is often necessary to position the patient. The so-called positioning is to make the patient lie on the bed of the treatment bed, adjust the posture and position of the patient, so that the affected part of the patient is in the most suitable position for ray irradiation. During a course of radiation therapy, the same specific area of ​​a patient is irradiated several times over a period of up to two months in order to achieve the best results. Therefore, we usually hope that the irradiated area of ​​the ray is as consistent as po...
