Purpose: To investigate the differences in perfusion CT dose between 4 distinct collimator configurations on a 64‐slice scanner.Method and Materials: An Alderson‐Rando head phantom was used in this study. A total of 110 LiF TLD‐100 with dimensions of 3×3×0.8 mm were inserted in the phantom holes. Slices 2 and 3 of the phantom were used with two TLD chips per hole imbedded in between 2 plastic rods so that the chips are in the middle of the slice. Another 7 TLD chips were placed on the phantom… CONTINUE READING
