1. An imaging system for processing image data of an object containing a component, comprising: an imaging device arranged to obtain image data; a processor adapted to: receive the image data from the imaging device; obtain a component model for the component; obtain an imaging device model for the imaging device; construct an unconstrained objective function based on the component model and the imaging device model; and construct a model of the object containing the component based on the unconstrained objective function and the image data; and a display device adapted to display an image for the object containing the component based on the model.
