Multi-slice detector design
(GE 4 slice scanner)
l 16 equal elements in z axis, 20mm
maximum collimator width *
l Can acquire 1, 2, or 4 images per rotation
l For example: with collimator at 10mm can
make 4 images @ 2.5mm, 2 images @
5mm or 1 image @ 10mm
l Thinnest slice thickness that can be
reconstructed depends entirely on
combination of slice thickness and table
speed
