1. A method for estimating a three-dimensional body surface of a patient located on a moveable patient table in a medical imaging system, the method comprising:
capturing, with a sensor, a sequence of surface images of the patient;
estimating, by a processor, the three-dimensional body surface of the patient by a machine-learned network in response to input of the surface images to the machine-learned network;
automatically determining, by the processor, an isocenter of the patient based on a regression of the estimated three-dimensional body surface of the patient and based on a position of the moveable patient table; and
positioning, by the processor, the patient via the moveable patient table based on the isocenter of the patient.
