1. A percutaneous-point determination device for determining a location of a point associated with a surface of an animal organ, comprising:

  • an ultrasound device configured to emit a focused ultrasound beam along an ultrasound beam axis having a known orientation with respect to the ultrasound device, the ultrasound device configured to output ultrasound data indicative of a distance from the ultrasound device to the point associated with the surface of the animal organ, the ultrasound device comprising a plurality of spatial markers having a known spatial relationship to the ultrasound device, the spatial markers configured to radiate energy;

    a position measurement device configured to detect energy radiated by the spatial markers to thereby determine spatial positions of the spatial markers and to output position data indicative of a location of the ultrasound device; and

    a computer configured to process the ultrasound data and position data to thereby determine the location of the point associated with the surface of the animal organ with respect to an on site reference coordinate system.
