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.

A dynamic vibration absorber (DVA) for an imaging system, comprising:
- 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.
A method, comprising:
- coupling a dynamic vibration absorber (DVA) comprising a vibrational tuner, a mount portion including one or more apertures, and a sprung portion to a mount surface of an imaging system via the mount portion;
- determining a vibration frequency of the DVA while rotating a rotor of the imaging system;
- and
- fine-tuning the vibration frequency of the DVA based on the determined vibration frequency;
- and
- wherein 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.
A system, comprising:
- a gantry;
- an x-ray radiation source coupled to the gantry and including an x-ray tube and a housing;
- a mount surface;
- and
- a dynamic vibration absorber (DVA) configured to couple to the mount surface of one of the gantry, the x-ray tube, or the housing via a mount portion including one or more apertures, the DVA comprising a sprung portion, and one or more interchangeable elements configured to adjust vibration characteristics of the DVA, wherein during operation of the 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 one or more interchangeable elements.
