Abstract
An imaging system (100) includes a stationary gantry (102), a rotating gantry (104) that rotates around an examination region about a z-axis, an annular support (106) that is statically affixed to the stationary gantry and that rotatably couples the rotating gantry to the stationary gantry, and a radial compliant ring (108) disposed between the annular support and the rotating gantry. In a variation, the imaging system also includes an axial compliant ring (112) disposed perpendicular to the radial compliant ring, statically affixed to the annular support and extending in part in a recess (206) of the rotating gantry.
Claims19
An imaging system, comprising:
- a stationary gantry;
- a rotating gantry that rotates around an examination region about a z-axis, the rotating gantry, including:
- a first recess;
- and
- a second recess located in the first recess;
- an annular support that is statically affixed to the stationary gantry and that rotatably couples the rotating gantry to the stationary gantry, wherein a sub-portion of the annular support protrudes in the first recess and a first surface of the sub-portion is adjacent to the second recess;
- and
- a radial compliant ring disposed between the annular support and the rotating gantry in the second recess, adjacent to the first surface of the sub-portion of the annular support.
A method, comprising:
- rotating a rotating gantry of an imaging system about a stationary gantry the imaging system, wherein the rotating gantry is rotatably affixed to the stationary gantry via an annular support and a radial compliant ring, which resides between the rotating gantry and the annular support in a first recess located in a second recess in the rotating gantry and adjacent to a surface of the annular support which is located in the first recess.
An imaging system gantry sub-system, comprising:
- an annular support that statically affixes to a stationary gantry of the imaging system and that rotatably couples a rotating gantry to the stationary gantry;
- a radial compliant ring disposed between the annular support and the rotating gantry in a recess in the rotating gantry and adjacent to a surface of the annular support, wherein the rotating gantry rotates along the radial compliant ring.
