    摘要： Systems, methods, and devices for medical imaging are disclosed herein. In some embodiments, a method for imaging an anatomic region includes receiving, from a detector carried by an imaging arm of an x-ray imaging apparatus, a plurality of images of the anatomic region. The images can be obtained during manual rotation of the imaging arm. The imaging arm can be stabilized by a shim structure during the manual rotation. The method can also include receiving, from at least one sensor coupled to the imaging arm, pose data of the imaging arm during the manual rotation. The method can further include generating, based on the images and the pose data, a 3D representation of the anatomic region.

    摘要： A deformable image registration phantom having a housing, an outer cylinder, a parallel eccentric inner cylinder, a ball and socket mount, and a target. The inner cylinder is rotatably mounted within the outer cylinder and the target is rotatably mounted, directly or indirectly, within the inner cylinder. Indexing detents are positioned on at least one of the housing, the outer cylinder, the inner cylinder, and the ball and socket mount and one or more detent pins positioned on another. The indexing detents are arranged about at least one rotational or translational axis of the phantom and the detent pins are configured to releasably engage with the indexing detents as the components of the phantom rotate or translate relative to one another.

    摘要： A system for detecting a scanning beam of x-rays includes one or more scintillator volumes oriented along an x-ray scan axis. The scintillator volume(s) receive x-rays transmitted through a target and produce scintillation photons responsively. Two or more ribbons of wavelength-shifting fibers (WSFs) are optically coupled to the scintillator volume(s) along the axis via a spatial periodic adjacency of the ribbons to the axis. The ribbons receive scintillation photons from the scintillator volume(s) via the spatial periodic adjacency as the x-ray beam scans over the scan axis. At least one respective photodetector coupled to an end of each respective ribbon detects the scintillation photons carried by the respective ribbon produces a respective signal. A signal combiner selectively combines signals from one or more ribbons, for beam positions along the scan axis, to create a combined signal representing a scan of the target. The scan can have enhanced spatial resolution.
