An imaging system () includes a gantry () that defines an examination region () and a subject support (). The subject support includes a tabletop () that supports an object or subject in the examination region for a scan of the object or subject and a base () that supports the tabletop. A support frame () supports the base. The base is moveably affixed to the support frame and moves between a plurality of predetermined locations, which are based on corresponding distances from the gantry. A support frame drive system () moves the base alternatively to one of the plurality of predetermined locations in response to an input signal indicative of the one of the plurality of predetermined locations, which corresponds to a location of interest for the scan of the object or subject.

Imaging system subject support

A method includes receiving a subject support motion disable signal indicative of at least one of power removal of an imaging system, a collision of a horizontally moving tabletop of the imaging system, a decoupling of a horizontal motion drive system configured to horizontally drive the tabletop, or a collision of a vertically moving subject support of the imaging system, wherein a vertical motion drive system drives the subject support vertical motion, and disabling, in response to receiving the subject support motion disable signal, at least one of tabletop horizontal motion or subject support vertical motion.

An imaging system () includes a rotating gantry () configured to rotate about an examination region () about a z-axis (), a subject support (), including a tabletop () configured to horizontally translate along the z-axis into and out of the examination region, a communications network () shared by the rotating gantry and the subject support, and a master motion controller () configured to control both rotational motion of the rotating gantry and translational motion of the tabletop over the communications network.

Imaging system rotating gantry and subject support motion control

An imaging system () includes a subject support () configured to carry a subject being imaged in an examination region of the imaging system and a subject support controller () that positions the subject support and hence the subject in the examination region for scanning the subject based on a motion algorithm which reduces subject support vibration during scanning relative to a trapezoidal or s-curve motion algorithm, for a given translation duration and a given translation distance.
