1. A method for patient weight estimation from surface data in a medical imaging system, the method comprising:
capturing, with a sensor, an outer surface of a patient, the surface data being from the capturing of the outer surface of the patient;
deforming a generic patient model to fit to the surface data of the patient;
extracting one or more values for each of a plurality of different body parts of the patient from the deformed generic patient model;
estimating a weight of each of the plurality of body parts of the patient by input of the one or more values for the plurality of different body parts to a respective machine-learned regressor for each of the plurality of body parts; and
applying radiation to the patient where an amount of radiation is based on a summed weight of the plurality of body parts.
