    Abstract: Various methods and systems are provided for reducing vibration in a rotating body of a medical imaging system. In an example, a dynamic vibration absorber (DVA) for a medical imaging system includes a mount portion including one or more apertures and adapted to fixedly couple to a mount surface within the imaging system; a sprung portion; and a vibrational tuner, where when the mount portion is mounted to the mount surface and during operation of the imaging system, the sprung portion moves relative to the mount surface, an amount of movement of the sprung portion based at least in part on the vibrational tuner.

    Abstract: Various methods and systems are provided for stationary CT imaging. In one embodiment, a method for an imaging system includes activating an emitter of a plurality of emitters of a stationary distributed x-ray source unit to emit an x-ray beam toward an object within an imaging volume, where the x-ray source unit does not rotate around the imaging volume, receiving the x-ray beam at a subset of detector elements of a plurality of detector elements of one or more detector arrays, sampling the plurality of detector elements to generate a total transmission profile, an attenuation profile, and a scatter measurement, generating a scatter-corrected attenuation profile by entering the total transmission profile, the attenuation profile, and the scatter measurement as inputs to a model, and reconstructing one or more images from the scatter-corrected attenuation profile.
