Abstract: A method of a radiotherapy or radiosurgery treatment comprises steps of: (a) providing a converging x-ray beam source configured for emitting a converging X-ray beam propagating along an axis thereof; (b) emitting the converging x-ray beam towards a volume of treatment (VOT) having a length along the axis of the converging X-ray beam ranging between 2 mm and 5 cm within a patient's body such that a waist portion is within the VOT; (c) propagating the beam through tissues previously located relative to the VOT (PO); the VOT per se and tissues distally located to the VOT (DO).

For at least one defined gesture, defined as a time sequence comprising hand poses, with each of the hand poses defined as a conjunction or disjunction of qualitative propositions relating to interest points on the hand, truth values are computed for the qualitative propositions using the hand pose information extracted from the received signal frames, and execution of the gesture is tracked, by using the truth values to determine which of the hand poses in the time sequence have already been executed and which of the hand poses in the time sequence is expected next.
