Abstract

The invention discloses a positioning method and device, an upper computer and a radiotherapy system, and belongs to the field of radiotherapy. The positioning method comprises the steps that the positions, in an infrared coordinate system, of reference mark points arranged on a noninvasive positioning device are obtained; according to the positions of the reference mark points in the infrared coordinate system and the relative positions between reference mark points in an electronic scanning image and a designated image center point, the position of the image center point in the infrared coordinate system is determined; on the basis of the position of the image center point in the infrared coordinate system, the position of an isocenter point of radiotherapy equipment in a patient supporting device coordinate system, and the conversion relation between the infrared coordinate system and the patient supporting device coordinate system, the first offset amount between the image center point and the isocenter point in the patient supporting device coordinate system is determined; and in the patient supporting device coordinate system, the first offset amount is adjusted to the presetoffset amount by adjusting the position of a patient supporting device. The positioning method is low in cost, and a patient is not harmed.

Description

technical field [0001] The invention relates to the field of radiotherapy, in particular to a positioning method, device, upper computer and radiotherapy system. Background technique [0002] Before radiotherapy, it is necessary to move the treatment bed to position the patient, so as to align the target point of the patient's affected part with the isocenter of the radiotherapy equipment, so as to ensure the accuracy of radiotherapy. Wherein, the central point refers to the point where the beam focus is located in the treatment chamber after the beam focus of the radiation source in the radiotherapy equipment is adjusted to the axis of the treatment chamber of the radiotherapy equipment. [0003] In related technologies, a positioning head frame or an image guide radiation therapy (image guide radiation therapy, IGRT) system is generally used to position a patient. Wherein, the positioning head frame fixes the patient's affected part through the positioning head nails, and...
