Abstract

The cross section of X-ray phase contrast caused by these low-Z elements is greatly bigger than the absorption. Therefore, in the field of X-ray imaging, the phase shift information can offer better imaging contrast. In this paper, we present a data transmission system for the detectors of a phase contrast X-ray human computed tomography prototype. This system contains 3 data collecting boards (DCB) and one data transmitting board (DTB). A slip ring is used to transmit the data from the rotator side to the stator side over a nowadays commonly used multi-mode fiber (MMF). On the rotator side, 3 DCBs act as the controller of these detectors. The function of the DTB is to store all image data from 3 DCBs and implement the commutation with PC. The test shows that this system can meet the requirement of the prototype.
