一、控制面板
机架两侧的控制面板按钮相同,功能一致,便于操作者在任意一侧操作(图1-1-1-2)。控制面板按钮的具体功能介绍见表1-1-1-1。

显示心电门控波形、
显示呼吸门控波形、
显示外周门控波形)以及当前连接线圈的信息(线圈名称和连接端口)(图1-1-1-3)。

三、检查床
检查床最大承重为227kg,磁体线圈直径为70cm,PET探测器直径为60cm,MR最大扫描范围为205cm,PET最大扫描范围为188cm,PET探测器纵向范围为25cm。检查床后上方有紧急脱扣开关手柄(红色方框),出现紧急情况时拉动此手柄,可将检查床板从磁体中拉出(图1-1-1-4);检查床后下方有5个踏板(图1-1-1-5),进行检查床与底座(图1-1-1-6)的连接、分离、电子对接及检查床的升降等操作。检查床前后端、机架后方的床板末端有不同扫描线圈的连接端口(图1-1-1-7)。

图1-1-1-7 线圈连接端口
A.P1:16通道上体部(upper anterior array,UAA)线圈连接端口;P2:19通道头颈联合(head neck unit,HNU)线圈连接端口;A:8通道头部线圈、乳腺线圈连接端口;B.P3:14通道中央分子成像阵列(central molecular imaging array,CMA)线圈连接端口;C.P4:16通道下体部(lower anterior array,LAA)线圈连接端口
四、线圈
根据检查部位选择相应线圈(图1-1-1-8)进行图像采集,其中19通道头颈联合线圈、8通道头部线圈、8通道乳腺线圈、16通道上体部线圈和16通道下体部线圈具有衰减校准的线圈模板,分离式头部线圈和柔线圈无衰减校准的线圈模板,使用无衰减校准线圈模板的线圈采集图像时,PET图像可能会出现伪影。
