Abstract
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.
