Abstract:

Methods, systems and computer-readable storage media relate to determining respiratory motion from motion data of a target to be treated. The methods may include processing motion data of a target to be treated obtained from at least one marker for at least one period. Each period including a plurality of time intervals. The processing including processing the motion data to determine an isocenter for each time interval along at least one of a plurality of axes of motion. The method may include determining at least one component of the motion data in at least one axis, the at least component corresponding to a subset of the motion data having a discrete value and/or a range of values; and determining respiratory motion from at least one component of the motion data. Radiotherapy treatment can be improved by determining the respiratory motion and the impact of respiration of a target.
