Embodiment Construction

[0047] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] As mentioned above, the existing technology takes a long time to position patients in the treatment room. During the time period occupied by the position, the radiotherapy equipment (hereinafter referred to as radiotherapy equipment) in the treatment room is occupied and cannot be effectively used. lead to a decrease in its usage. In order to solve this technical problem, an embodiment of the present invention provides a patient positioning method, which can effectively improve the utilization rate of radiotherapy equipment.

[0049] The patient positioning method provided by the embodiment of the present invention includes: acquiring the setup parameters of the patient located in the setup area, wherein the setup parameters are the required off...

Abstract

The invention discloses a patient positioning method and device, and relates to the field of radiotherapy systems. The method comprises the steps of: acquiring a positioning parameter of a patient ina positioning area, wherein the positioning parameter is an offset amount needed by the patient when a to-be-treated part of the patient coincides with a virtual isocenter point; and adjusting the position of the patient in a treatment room according to the positioning parameter and a preset position relationship between the virtual isocenter point and the isocenter point of radiotherapy equipmentso as to enable the to-be-treated part of the patient to coincide with the isocenter point of the radiotherapy equipment. According to the above-mentioned patient positioning method, the patient is pre-positioned in the positioning area before entering the treatment room, and the patient is rapidly and accurately positioned after entering the treatment room on the basis of the pre-positioned position, so the positioning time of the patient in the treatment room can be significantly saved, and the purpose of improving the utilization rate of radiation treatment equipment is achieved.

Description

technical field [0001] The invention relates to the field of radiotherapy systems, in particular to a patient positioning method. Background technique [0002] Radiation therapy technology is one of the important means of treating tumors at present. It uses radiation to irradiate the patient's lesion to achieve the purpose of treatment. During the treatment process, it is very important to accurately position the patient and ensure the consistency of the radiation position and the lesion position. [0003] The related technology uses the following method to position the patient: in the treatment room, the therapist positions the patient lying on the treatment bed, and then moves the patient into the treatment area of ​​the radiotherapy equipment so that the target point of the patient is aligned with the isocenter of the radiotherapy equipment. Overlap, and then treat the patient. [0004] However, for the entire treatment process, the time actually used for treatment is r...
