Provided is a method for locating a tumor. The method includes: performing image registration on a projection image of the tumor and a first standard image to acquire a first offset; generating a second standard image based on the first offset; performing image registration on the projection image and the second standard image to acquire a second offset; and updating the second standard image based on the second offset and executing the operation of image registration on the projection image and the second standard image again in response to the second offset satisfying a virtual re-sampling condition; or outputting an accumulated offset in response to the second offset not satisfying the virtual re-sampling condition, wherein the accumulated offset is a sum of the first offset and the second offset acquired by executing the operation of image registration.

Method and apparatus for locating tumor and radiotherapy system

An image-guided method and radio therapy device are provided. The method includes: acquiring a rotation offset, a planned image and a real-time image of a target object; and determining a tracking offset based on the rotation offset, the planned image and the real-time image, the tracking offset being used for tracking the target object; where the rotation offset is generated by a position difference of the target object in a planning stage and a treatment stage. The planned image of the target object is acquired in the planning stage. The tracking offset is determined based on the rotation offset, the planned image and the real-time image. The tracking of the target object based on the tracking offset compensates for image distortion caused by the deflection of the position of the target object in the planning stage and the treatment stage.

Image-guided method, radio therapy device, and computer storage medium

Embodiments of the present disclosure provide a method and an apparatus of correcting a collimator, which may correct a position of a collimator of a gamma knife apparatus. The method includes: separately obtaining a projection image of rays sequentially passing through collimation holes and an isocenter plane in the collimator in cases where the collimator moves to M positions; determining a target position with a highest degree of alignment of the collimator from the M positions according to obtained projection images of rays; recording position parameters corresponding to the target position, so as to control the collimator to move to the target position in a case where the a gamma knife apparatus is used for treatment.
