    • A collimator for collimating high-energy photons, which may be used in medical imaging (e.g., nuclear medicine). The collimator has holes through the thickness (height) of the collimator, with the holes arranged in groups or clusters. The collimator may be used with a detector having an array of pixels, wherein each group of holes may be associated with a corresponding pixel, thereby providing multiple collimator holes per pixel. In one embodiment, each group of holes has septa of a given width separating the holes in that group, and each group of holes is separated from neighboring groups by septa of another, greater width. In another embodiment, the intra-group septa may be recessed from the top and/or bottom surface(s) of the collimator such that these septa have a smaller thickness (height) than the inter-group septa.
    • 用于准直可能用于医学成像(例如核医学)的高能光子的准直仪。 准直器具有穿过准直器的厚度(高度)的孔,孔以组或簇排列。 准直器可以与具有像素阵列的检测器一起使用,其中每组孔可以与相应的像素相关联,从而为每个像素提供多个准直器孔。 在一个实施例中,每组孔具有分隔该组中的孔的给定宽度的隔片,并且每组孔通过另一较大宽度的隔膜与相邻组分开。 在另一个实施例中,组内隔膜可以从准直器的顶部和/或底部表面凹入,使得这些隔片具有比组间隔膜更小的厚度(高度)。
