Relatively few seven-pinhole collimator systems purchased within the last three years are still in routine use. This paper describes a nontomographic use of the collimator for thyroid scanning. One image is obtained which simultaneously shows seven different projections of the thyroid gland. The diagnosis of thyroid abnormalities can frequently be made from this single composite image without the requirement for additional images. Further information can be obtained when needed by computer processing the image into tomographic slices.
在过去三年中购买的七针孔准直器系统仍在常规使用的相对较少。本文描述了该准直器在甲状腺扫描中的非断层扫描用途。获得了一幅图像，该图像同时显示了甲状腺的七个不同投影。通常可以从这张单一的合成图像中做出甲状腺异常的诊断，而无需额外的图像。如有需要，通过计算机将图像处理成断层切片可获得更多信息。
