1. A method of monitoring movement of a volume of tissue to facilitate treatment thereof, the method comprising:
- computationally identifying, within a voxel coordinate space, voxels corresponding to the volume of tissue prior to movement thereof;
associating, in a computer memory, treatment-related attributes with at least some of the voxels;
determining parameters characterizing movement of the tissue;
based on the determined parameters, computationally shifting positions of the voxels within the voxel coordinate space; and
altering at least one treatment parameter based on the treatment-related attributes of the shifted voxels.

Abstract
Treatment of moving tissue may be facilitated by identifying voxels within a volume of the tissue, associating treatment-related attributes with the voxels, and shifting positions of the voxels based on the tissue movement. One or more treatment parameters may then be altered based on the treatment-related attributes of the shifted voxels.

16. A method of treating a volume of tissue by exposure of the tissue to energy from a source, the method comprising the steps of:
-
identifying, within a voxel coordinate space, voxels corresponding to the volume of tissue; associating treatment-related attributes with at least some of the voxels; detecting movement of the tissue; characterizing the movement in three dimensions and, based thereon, computationally shifting positions of the voxels within the voxel coordinate space, the shifted voxels retaining the attributes associated therewith; and treating the tissue based on the characterized movement and the attributes of the shifted voxels. - View Dependent Claims (17, 18)
