Abstract

An imaging system (100) includes a gantry (101) that defines an examination region (106) and a subject support (112). The subject support includes a tabletop (116) that supports an object or subject in the examination region for a scan of the object or subject and a base (114) that supports the tabletop. A support frame (132) 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 (134) 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.

Claims26

Dependent claims

An imaging system, comprising:

a gantry with an examination region;
a subject support, including:
a tabletop configured to support an object or subject in the examination region;
and a base configured to supports the tabletop;
and
a support frame, including:
a first elongate bracket with a first leg;
a second elongate bracket with a second leg, wherein the first and second elongate brackets are arranged parallel to each other and separated from each other by a non-zero distance with the first and second legs facing each other;
a cradle with a first side and a second opposing side, both extending parallel to the first and second legs, wherein the cradle is configured to support the base;
a first slide bearing including a first stationary rail affixed to the first leg and a first moveable member configured to slide in the first rail and affixed to the first side facing the first leg;
and
a second slide bearing including a second stationary rail affixed to the second leg and a second moveable member configured to slide in the second rail and affixed to the second side facing the second leg,
wherein the cradle is moveable, via the first and second bearings, in two directions within the first and second elongate brackets along the first and second elongate brackets and extends out past the first and second elongate brackets in at least a first of the two-directions when at a first predetermined position, and extends out past the first and second elongate brackets in at least a second of the two-directions when at a second predetermined position.

10 more elements

A computer readable storage medium encoded with computer readable instructions, which, when executed by a processer, cause the processor to:

move a cradle a support frame of a subject support of an imaging system, via a bearing, between first and second elongate brackets of the support frame to a first predetermined position for scanning, wherein the bearing includes stationary rails affixed to legs of the first and second elongate brackets facing each other and moveable members configured to slide in the rails and affixed to opposing sides of the cradle facing the brackets, and the cradle is moveable in two directions within the first and second elongate brackets along the first and second elongate brackets and extends out past the first and second elongate brackets in at least a first of the two-directions when at a first predetermined position, and extends out past the first and second elongate brackets in at least a second of the two-directions when at a second predetermined position.
