IMAGING SYSTEM GANTRY

摘要

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.

1. 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.
