Claim:
1. A method, implemented by a processor, for locating a target in a three-dimensional (3D) volume, the method comprising: receiving a 3D medical image containing a region of interest of the target; extracting, by the processor, a plurality of two-dimensional (2D) slices from the 3D medical image; determining, by the processor, a 2D patch for each 2D slice, wherein the 2D patch corresponds to an area of the 2D slice associated with the target; determining, for at least one 2D patch, an offset value reflecting a distance between a location of the at least one 2D patch and a location of the target; and converting, by the processor, each 2D patch to an adaptive filter model for determining a location of the region of interest, wherein at least one adaptive filter model includes a function for determining a confidence score when the corresponding adaptive filter model is applied to a 2D image acquired by an image acquisition device during a treatment session, the confidence score indicating a relative degree of match between the at least one adaptive filter model and a particular location of the 2D image.
