The subject matter disclosed herein relates to X-ray imaging systems, and more specifically to digital X-ray imaging systems. In one embodiment, an imaging system includes an X-ray source configured to emit X-rays. The imaging system also includes an X-ray detector configured to detect the emitted X-rays and produce a corresponding electrical signal. The imaging system also includes a gantry configured to at least partially revolve the X-ray source and the X-ray detector about a primary rotational axis. The X-ray detector is coupled to the gantry so that a diagonal of the X-ray detector is oriented substantially perpendicular to the primary rotational axis.

Some embodiments are associated with an X-ray source configured to generate X-rays directed toward an object, wherein the X-ray source is to: (i) generate a first energy X-ray pulse, (ii) switch to generate a second energy X-ray pulse, and (iii) switch back to generate another first energy X-ray pulse. A detector may be associated with multiple image pixels, and the detector includes, for each pixel: an X-ray sensitive element to receive X-rays; a first storage element and associated switch to capture information associated with the first energy X-ray pulses; and a second storage element and associated switch to capture information associated with the second energy X-ray pulse. A controller may synchronize the X-ray source and detector.

Methods, systems and non-transitory computer readable media that store instructions executable by one or more processors for performing an interventional procedure are presented. One or more pulses are delivered to an intravascular region of interest (ROI) in a subject using at least one image sensor and at least one forward-looking flow sensor disposed at a distal end of an integrated intravascular device. Further, one or more images corresponding to the ROI are reconstructed using imaging signals received in response to the pulses delivered by the image sensor. Additionally, one or more flow characteristics corresponding to the ROI are determined based on the signals received in response to the pulses delivered by the flow sensor. The determined flow characteristics are used for computing one or more functional parameters corresponding to the ROI. An assessment of the subject may be provided based on the reconstructed images and/or the functional parameters.
