1. A system for robotic navigation in nuclear probe imaging, the system comprising: a nuclear detector ( 12 ) for detecting ( 50 ) radiation; a robotic assembly ( 11 ) connected with the nuclear detector ( 12 ), the robotic assembly ( 11 ) operable to move the nuclear detector ( 12 ) relative to a patient; a three-dimensional scanner ( 19 ) positioned to view the patient; and a processor ( 30 ) configured to control movement of the robotic assembly ( 11 ) to scan the patient with the nuclear detector ( 12 ) in a pattern, the movement being a function of the view of the patient by the three-dimensional scanner ( 19 ).
