PCD-CT 51	120	450	~170	0.6	29	51	1,024	50	50	200	50	Qr80u
PCD-CT 30	120	450	~170	0.6	29	30	2,048	15	50	200	50	Qr80u
PCD-CT 18	120	450	~170	0.6	29	18	2,048	8.8	50	200	50	Qr80u
EID-CT 1000	120	1,000	~360	0.6	49	51	512	100	100	400	100	Ur81-3
EID-CT 600	120	600	~210	0.6	29	51	512	100	100	400	100	Ur77-3

The computed tomography dose index (CTDI_vol) was supplied by the CT scanner software. The numbers after the type of scanner correspond to the field of view in mm (PCD-CT) and quality reference tube load in mAs (EID-CT)
