摘要:

由这些低Z元素引起的X射线相衬的截面远大于吸收。因此,在X射线成像领域,相移信息可以提供更好的成像对比度。在本文中,我们提出了一个数据传输系统的探测器的相位衬度X射线人体计算机断层成像原型。该系统包括3块数据采集板(DCB)和1块数据传输板(DTB)。滑环用于通过目前常用的多模光纤(MMF)将数据从转子侧传输到定子侧。在旋转器侧,3个DCB充当这些检测器的控制器。DTB的功能是存储来自3个DCB的所有图像数据,并实现与PC机的数据交换。测试表明,该系统能够满足样机的要求。

英文摘要:

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.
