一个原型的PET相机已经设计，并正在建造测试的概念，并开发工程设计和生产方法的可变场PET相机。该设计的长期目标是开发一种低成本、高分辨率的PET相机。该相机有八个探测器头，形成一个紧密排列的八边形探测器环，平均直径为44厘米，用于脑/乳房和动物模型成像。头部可径向平移至最大环直径70 cm，用于全身成像。在较大直径模式下，摄像机在成像过程中旋转45/spl deg/。摄像头可以设置在中间位置，以使摄像机适合对象大小，从而最大限度地提高检测灵敏度和采样均匀性。实现的检测器设计是象限共享光电倍增管（PMT）的设计，使用圆形19毫米PMT。摄像机同时拍摄27个切片。BGO探测器的间距大小为27/SPL倍/2.7毫米。初步的模拟研究已经进行了评估的分辨率，灵敏度和采样均匀性。
A prototype PET camera has been designed and is being constructed to test the concept, and develop the engineering design and production methodology for a variable field PET camera. The long term goal of the design is to develop a lower cost, high resolution PET camera. The camera has eight detector heads which form a closely packed octagon detector ring with an average diameter of 44 cm for brain/breast and animal model imaging. The heads can be translated radially to a maximum ring diameter of 70 cm for whole body imaging. In the larger diameter modes, the camera rotates 45/spl deg/ during imaging. The camera heads can be set to intermediate positions to fit the camera to the subject size to maximize detection sensitivity and sampling uniformity. The detector design implemented is the quadrant sharing photomultiplier (PMT) design using circular 19 mm PMT. The camera images 27 slices simultaneously. The BGO detector pitch size is 27/spl times/2.7 mm. Preliminary simulation studies have been performed to evaluate the resolution, sensitivity, and sampling uniformity.
