Table 4.

Large Body SFOV, 80 mm coverage, helical pitch ≤ 0.992.

Patient size	Preset Family (Scan FOV, focal spot, coverage)	Rot time (s)	Pitch	Min CTDIvol (mGy)	Max CTDIvol (mGy)
Small	Large Body, Large, 80 mm	0.5	0.992	4.7	12.2
Medium	Large Body, Large, 80 mm	0.6	0.508	10.9	28.4
Large	Large Body, Large, 80 mm	1	0.508	17.2	45.5
Extra large	Large Body, XLarge, 80 mm	1	0.508	49.7	53.7

This profile is designed for abdomen and pelvis protocols, where patient motion is not an issue but there is concern about artifacts from helical pitches larger than 1.
