Systems, methods, and devices for medical imaging are disclosed herein. In some embodiments, a system for imaging an anatomic region includes one or more processors, a display, and a memory storing instructions that, when executed by the one or more processors, cause the system to perform various operations. The operations can include generating a 3D reconstruction of an anatomic region from first image data obtained using an imaging apparatus, and identifying a target structure in the 3D reconstruction. The operations can also include receiving second image data of the anatomic region obtained using the imaging apparatus, and receiving pose data of an imaging arm of the imaging apparatus. The operations can further include outputting, via the display, a graphical representation of the target structure overlaid onto the second image data, based on the pose data and the 3D reconstruction.

Systems and methods for detecting and imaging high Z agents within anatomy of a subject are provided. A fast photon counting detector array is positioned relative to the subject to detect coincident photons having 511 keV energy and opposing directions. The trajectories of those photons can be determined, thereby leading to the origin of the photons, namely, the location of an annihilation event. Based on the number of these events, the high Z agent can be detected and/or imaged within the anatomy, thereby providing useful information for clinicians regarding the distribution of high Z agents in the anatomy and/or the behavior of the therapeutic medical high energy photon source.

The technology provided herein relates to a dual energy CT scanner and associated image acquisition and reconstruction technology that increases spatial and temporal resolution over conventional dual energy CT scanner designs. A dual energy filter positioned at the source as disclosed herein includes alternating materials that attenuate the X-ray source to different levels, thereby providing spectral separation. As such, the object to be imaged by X-ray beams is probed by both a low and a high energy spectrum. The X-ray spectra at the source is divided along the detector channel direction (a columns direction).
