    Abstract: Exemplary embodiments are directed to imagining detectors and methods of fabricating the imagining detectors for use in medical imagining systems. In exemplary embodiments, a detector for an imaging device include a continuous unpatterned photoelectric material that forms a portion of a photosensor and an electrode disposed with respect to the photoelectric material to form an anode or cathode of the photosensor. Data readout lines connected to the outputs of transistors of the detector can be susceptible electronic noise from capacitive coupling between the electrode of the photosensor. In exemplary embodiments of the present disclosure, a lateral offset and/or vertical offset between the electrode and the data readout lines can be formed to control the capacitive coupling between the electrode and the data readout line.

    Abstract: Various embodiments discussed herein utilize a C-shaped imager to provide images with a minimal footprint, such as may be suitable in a surgical context. In addition the systems and methods described herein allow for suitable angular (i.e., azimuthal) scan coverage about the patient. To provide real-time 3D imaging, multiple X-ray tubes or a distributed X-ray source may be employed, coupled with an extended detector or multiple detectors. To reconstruct high-quality volumes, in some implementations reconstruction techniques may be employed that utilize pre-operative (pre-op) computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (U/S), or other suitable modality images or data as prior information.
