Abstract: A process for fabricating an organic x-ray detector is presented. The process includes forming a multilayered structure that includes disposing a first electrode layer on a thin film transistor array, disposing an organic absorber layer on the first electrode layer, and disposing a second electrode layer on the organic absorber layer. The process further includes disposing a scintillator layer on the second electrode layer and thermally treating the multilayered structure after the step of disposing the second electrode layer. An organic x-ray detector fabricated by the process is further presented. An x-ray system including the organic x-ray detector is also presented.

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.
