Title:
PET IMAGING ROD SOURCE DEVICE AND PET EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2016/188352
Kind Code:
A1
Abstract:
Disclosed is a PET imaging rod source device, comprising a rod source body (500), a first rotating module (100) for driving the rod source body (500) to rotate around the axial direction at a uniform speed, and a second rotating module (200) for driving the rod source body (500) to rotate around the centre-axis, wherein the first rotating module (100) comprises a first power assembly (110), a first transmission assembly (120) and a rotating arm structure (130); the first power assembly (110) is parallel to the axial direction; the rotating arm structure (130) is perpendicular to the axial direction; the first power assembly (110) and the rotating arm structure (130) are in transmission connection via the first transmission assembly (120); the second rotating module (200) is fixed at the end of the rotating arm structure (130) far away from the first transmission assembly (120); an output end of the second rotating module (200) is parallel to the axial direction; and the output end of the second rotating module (200) is directly connected to the rod source body (500) to drive the rod source body (500) to rotate around the centre-axis, and at the same time follows the movement of the first power assembly (110) to drive the rod source body (500) to rotate around the axial direction, so that all detector units can be more uniformly irradiated when the rod source body (500) is subjected to normalization correction, and a more accurate correction result is obtained.
