1. A method of obtaining an interventional cone-beam computed tomography (CBCT) image of a subject comprising: identifying task-based performance predictors that affect the quality of an image; applying the task-based performance predictors that affect the quality of the image to properties of a reconstruction of the image; identifying projection views to maximize task performance, wherein the identifying begins with a projection view that maximizes detectability, proceeding to a next-best view, and continuing in an orbit of a C-arm of an imaging machine, wherein the identified projection views form an arbitrary orbit with variations in rotation angle, θ, and obliquity, φ, throughout the orbit; and initiating a CBCT scan of the subject following the identified projection views to generate the image according to the identified and applied task-based performance predictors.
