System and method for imaging a patient

A method for imaging a subject comprising:

• displaying, via a controller, one or more selectively adjustable markers that define an image stack;
• reconstructing on demand, via the controller, one or more images within the image stack based at least in part on a plurality of projections generated by receiving, at a radiation detector, electromagnetic rays transmitted through the subject via a radiation source;
• and
• wherein the one or more on demand images are separately reconstructed by the controller prior to reconstruction of a majority of images in the image stack.

A non-transitory computer readable medium storing instructions configured to adapt a controller to:

• display one or more selectively adjustable markers that define an image stack;
• reconstruct on demand one or more images within the image stack based at least in part on a plurality of projections generated by receiving, at a radiation detector, electromagnetic rays transmitted through a subject via a radiation source;
• and
• wherein the one or more on demand images are separately reconstructed by the controller prior to reconstruction of a majority of images in the image stack.
