摘要：
A cradle drive mechanism, a table and a patient imaging and carrying apparatus are provided. The cradle drive mechanism includes: a first portion, which is arranged on a main base and has a belt drive structure, wherein the belt drive structure is used to connect a cradle and drive the cradle to make a reciprocating motion a second portion, which is arranged on a secondary base and has a secondary supporting and rotating member, wherein the second portion and the first portion form a gap therebetween, and the secondary supporting and rotating member is used to support the cradle and two guiding and rotating members, which are arranged on the second portion and/or the first portion for guiding the cradle to move linearly. The present application can simplify the structure by adoption of the belt drive structure. Further, the gap between the second portion and the first portion does not attenuate the X-ray additionally, so the dose of the X-ray emitted can be decreased.
