1. A computer-implemented method executed on at least one processor of at least one computer for issuing a control signal useable by an associated medical device for controlling operation of the medical device, the method comprising:
determining, by the at least one processor, a motion trajectory of a structure associated with at least one body part of a patient, wherein the motion trajectory is indicative of a respiratory movement of the structure;
acquiring, at the at least one processor, surface data representative of a position of a surface region of the patient;
computing, by the at least one processor, an intersection of the determined motion trajectory and the acquired surface data;
determining, by the at least one processor, a breathing signal of the patient based on the computed intersection, wherein the breathing signal is indicative of a breathing state of the patient; and
issuing, by the at least one processor, the control signal to the associated medical device for controlling operation of the medical device, based on the determined breathing signal of the patient, for carrying out a medical procedure on the patient.
