Abstract

An imaging system for processing image data of an object containing a component. The imaging system includes an imaging device arranged to obtain image data and a processor. The processor is 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.
