一种全身PET与CT联用装置
摘要：
本发明提供一种全身PET与CT联用探测器及装置，其包括共中轴线且分前后设置的CT扫描架和PET探测腔；所述CT扫描架具备外壳，且具备一垂直于中轴线的圆柱形CT扫描通道；所述PET探测腔由复数个PET探测模件相邻以形成，PET探测晶体均向腔内方向布置；所述PET探测腔整体封闭或者在与CT扫描架相邻一侧形成第一开口；前述复数个PET探测模件，每个PET探测模件都由PET探测晶体和光电传感器阵列和光导组成；除前述第一开口外，该PET探测腔的所有空隙截面积均小于前述PET探测晶体中最小一个的探测表面积。
摘要（英）：

The present invention provides a whole body PET and CT combined detector and device. The whole body PET and CT combined device comprises a CT scanning rack and a PET detection chamber in a common central axis and front and rear arrangement; the CT scanning rack is provided with an outer shell and also has a cylindrical CT scanning channel vertical to a central axis; the PET detection chamber is formed by a plurality of PET detection modules adjacent to each other and PET detection crystals are all arranged in a direction towards to the chamber; the PET detection chamber is entirely closed or one side adjacent to the CT scanning rack forms a first opening; each of the plurality of the PET detection modules is composed of the PET detection crystals, a photoelectric sensor array and light guides; and except for the first opening, all gap cross-sectional areas of the PET detection chamber are all smaller than a detected superficial area of the smallest one of the PET detection crystals.
