In this paper we introduce a new application of the sevenpinhole (7P) collimator: tomographic imaging of the thyroid. The collimator design has been reoptimized for this particular application by diminishing the distance from the collimator plate to the crystal and by choosing a smaller pinhole diameter. To reconstruct thyroid images from the two-dimensional projection data we use a method which we developed for 7P tomographic imaging of the heart [1]. Phantom experiments and patient studies demonstrate that this new device is capable of producing tomographic images of good quality and high resolution. Therefore, it seems to offer a promising alternative to conventional planar imaging of the thyroid (using a single-pinhole collimator).
在本文中，我们介绍了七孔准直器的一种新应用：甲状腺断层成像。为了将该应用特殊化，我们重新优化了准直器的设计，减小了准直器板到晶体的距离并选择了更小的针孔直径。为了从二维投影数据重建甲状腺图像，我们使用了我们为心脏的七孔断层成像开发的方法[1]。体模实验和临床研究表明，这种新设备能够产生高质量和高分辨率的断层图像。因此，它似乎为甲状腺的传统平面成像（使用单孔准直器）提供了一种有前途的替代方案。
