一种适应性保持装置已经开发出来，用于在计算机断层扫描（CT）过程中保持和对准镇静灵长类受试者的头部。该设备用于获得9名受试者下颌骨种植体植入前后的CT扫描研究的近距离复制。几何和材料属性是从这些研究中提取出来的，目的是开发有限元计算机模型。该装置由低密度丙烯酸制成，由一个水平底座组成，横向支撑固定在其上。该装置放置在CT台上，与扫描光束轴向对齐。使用头部固定装置，可以对灵长类植入物进行可重复的、校准的CT研究。
An adaptable retention device has been developed for the purpose of holding and aligning the head of a sedated primate subject during computed tomography (CT) scan procedures. The device is used to obtain a close reproduction of CT scan studies at a time before and after dental implant placement in the mandibles of nine subjects. Geometric and material properties are extracted from these studies for the purpose of developing finite elements computer models. The device is constructed of low-density acrylic and consists of a horizontal base to which lateral supports are affixed. The device is placed on the CT table and axially aligned with the scan beam. Repeatable, calibrated CT studies of primate implant subjects were possible using the head holding device.
