The collimator assembly, as set forth in claim 9, wherein at least a number of the first plurality of fins extends from a body of the first blade at an angle of between 0 and 10 degrees from perpendicular with respect to the body of the first blade, and wherein at least a number of the second plurality of fins extends from a body of the second blade at an angle of between 0 and 10 degrees from perpendicular with respect to the body of the first blade. 12. The collimator assembly, as set forth in claim 9, wherein each or the first plurality or fins extends from only one side of the first blade, and wherein each of the second plurality of fins extends from only one side of the second blade. 13. The collimator assembly, as set forth in claim 9, wherein a first number of the first plurality of fins extends from a first side of the first blade and wherein a second number of the first plurality of fins extends from a second side of the first blade, and wherein a first number of the second plurality of fins extends from a first side of the second blade and wherein a second number of the second plurality of fins extends from a second side of the second blade. 14. The collimator assembly, as set forth in claim 9, wherein the first plurality of fins is coupled to the second plurality of fins. 15. The collimator assembly, as set forth in claim 9, wherein the second plurality of fins is coupled to the first blade. 16. An imaging detector assembly comprising:a detector array;a scintillator assembly configured to receive incident radiation and configured to convert the incident radiation to light for transmission to the detector array; anda collimator assembly comprising:a plurality of blades arranged in parallel with respect to one another;wherein each of the plurality of blades comprises a respective plurality of fins coupled to the blade and extending there from;wherein each of the respective plurality of fins is coupled to an adjacent one of the plurality of blades; andwherein a body of each of the plurality of blades comprises a different material than the respective plurality of fins. 17. The imaging detector assembly, as set forth in claim 15, wherein each of the respective plurality of fins extends at an angle of approximately 90° with respect to the blade. 18. The imaging detector assembly, as set forth in claim 15, wherein at least a number of each of the respective plurality of fins are arranged at angles between approximately 85° and 95° relative to the length of the blade. 19. The imaging detector assembly, as set forth in claim 15, wherein each of the respective plurality of fins extends from only one side of the blade. 20. The imaging detector assembly, as set forth in claim 15, wherein a first number of each of the respective plurality of fins extends from a first side of the blade and a second number of each of the respective plurality of finds extends from a second side of the blade. 21. The imaging detector assembly, as set forth in claim 15, wherein each of the respective plurality of fins is coupled to the respective plurality of fins on an adjacent one of the plurality of blades. 22.
