一个小的4厘米x4厘米的原型CdTe伽玛相机已经建成，证明灵敏度和空间分辨率优于标准的愤怒相机。相机是基于包含在层流准直器内的线性固体探测器阵列，该阵列将视野限制在一维。阵列逐步旋转180°，记录每个位置的数据并进行计算机处理。这种技术相对于多孔准直器的灵敏度有了很大的提高。已获得临床图像，并计划安装更大的CdTe相机。
A small 4 cm X 4 cm prototype CdTe gamma camera has been constructed which demonstrates sensitivity and spacial resolution superior to the standard Anger camera. The camera is based on an array of linear solid state detectors contained within a laminar collimator which confines the field of view to one dimension. The array is rotated stepwise through 180° and data from each position recorded and computer processed. This technique leads to a major enhancement in sensitivity relative to the multihole collimator. Clinical images have been obtained and a larger CdTe camera is planned.
