Abstract
Provided are a method for tracking tumor location and a radiotherapy apparatus, relating to the field of medical equipment technology. The method is applied to a radiotherapy apparatus comprising a first detector and at least one radiation source, and comprises emitting, from the radiation source, ray beams having a predetermined intensity, the ray beams being partially scattered after passing through a body lesion; receiving, by the first detector, a portion of scattered ray beams to acquire scattering data of the lesion; determining a relative location relationship between the lesion and a target region according to the acquired scattering data; and adjusting at least one of the ray beam intensity, lesion location and target region location according to the determined relative location relationship, such that the lesion receives irradiation of the ray beams having an adjusted predetermined intensity at the target region location.
