Abstract:
1. A photon collimator, comprising: a monolithic block of absorptive photon-attenuating material having upper and lower opposite sides, the sides respectively having length and width, the monolithic block defining first and second pluralities of uninterrupted integrally formed continuous planar septa slats across the entire block length of a respective opposite block side; each slat in each respective first and second slat plurality having an elongated length dimension greater than its thickness and depth dimensions, with each respective plurality of slats oriented in a respective opposed pattern array that is laterally spaced along its respective block side width, the respective first and second pattern arrays skewed in relative alignment and in contact with each other intermediate the upper and lower sides; and respective first and second uninterrupted aperture channel voids removed from respective opposite block sides that are defined between and along the entire length of each corresponding pair of respective opposing pluralities of slats; the respective first and second aperture channels in communication with each other and forming with the first and second slat pluralities arrays a pattern of polygonal cross-section through-apertures from the upper block side to the lower block side that define a collimator array.
