Abstract:
1. A medical imaging system comprising: a camera head including a camera surface, said camera surface defining a field of view where a patient's body is to be placed; a mechanism for rotating said camera head around said patient's body in a first plane and moving said camera head in a second plane substantially parallel to said first plane; a light source being adapted to emit a light beam which travels over and substantially parallel to said camera surface, said light source being mounted on said camera head; a light detector being adapted to detect said light beam emitted from said light source at least at multiple heights over said camera surface, said light detector being mounted on said camera head and being spatially separated from said light source such that a space between said light source and said light detector is sufficient to place said patient's body therein; a module for analysing characteristics detected by said light detector and measuring a distance between said patient's body and said camera surface; and a controller for controlling said mechanism based on an output of said module to adjust a relative distance between said patient's body and said camera surface.
