1. An apparatus for patient position or motion monitoring, the apparatus comprising:
a first energy source configured to emit a first energy from a first location to a second location, wherein a distance between the first location and the second location is variable in response to a movement by a patient, the first energy source including an accelerometer configured to sense an orientation of the first energy source;
a second energy source configured to emit a second energy to a surface of the patient support;
a processor configured to
determine a characteristic associated with the patient using a time-of-flight technique based on the first energy reflected from the patient and the orientation of the first energy source, the characteristic comprising a breathing characteristic including a breathing phase including breathing phase values,
determine a distance between the second energy source and the surface of the patient support based on the second energy reflected from the surface of the patient support to the second energy source, and
gate an application of a treatment to the patient based on the breathing phase values; and
a support structure having a mounting device, a vertical support and a telescopic arm, the support structure configured to:
mount to a patient support via the mounting device, the patient support including longitudinal edges extending along a length of the patient support and transverse edges extending perpendicular to the longitudinal edges, the mounting device configured to be removably coupled to one of the transverse edges of the patient support, and
maintain the first energy source and the second energy source at a fixed position with respect to the patient support;
wherein the processor is configured to repeatedly determine the characteristic associated with the patient based on the first energy reflected from the patient while the support structure maintains the first energy source at the fixed position with respect to the patient support; and
wherein, when mounted, the vertical support extends vertically from the mounting device and the telescopic arm extends from an end of the vertical support over the patient support.
