Summary of the information recorded by a radiation dose monitoring system per modality and implementation level

	Level	Recorded parameters
Patient information	I	Age, sex
	II	Height, weight
	III	BMI, Patient Effective Diameter
Computed tomography	I	CTDIvol or CTDIw, Phantom Type, DLP, and anatomical district per each series (including localizer, contrast monitoring, etc.)
	II	kV, mAs (minimum and average value), mA (minimum and average value), rotation time, collimation, pitch, slice thickness, and scanning range per each series
	III	Automated tube current modulation system descriptors (Noise Index, Effective mAs, etc.), reconstruction algorithm (if iterative the related strength should also be reported), field of view, if perfusion study the number and acquisition timing should also be reported, “virtual filter” applied to save radiation dose on a particular organ (specify the organ), SSDE, water equivalent diameter, and current profile across z axis
Angiography	I	Total KERMA air product (KAP), fluoroscopy KAP, radiography KAP, anatomical region (i.e., chest, abdomen, etc.)
	II	Total number of exposure events Per each exposure event: kV, mA, mAs, frames/second, filtration, fluoroscopy time, radiography image numbers, KAP and KERMA at the patient entrance reference point, X-ray tube position, source–detector distance (SDD), FOV, radiation field size
	III	Table position, source–skin distance (SSD), indication of the different contribution of air KAP and KERMA per each exposure event and per orientation angle, peak skin dose (PSD)
Digital radiography	I	KAP per each exposure event, anatomical region (i.e., chest, abdomen, etc.)
	II	Per each exposure event: kV, mAs, filtration, source–detector distance (SDD), radiation field size, detector radiation dose, tube orientation, air KERMA at reference point
	III	Source–skin distance (SSD)
Digital mammography	I	Air skin KERMA, AGD per each exposure event
	II	Per each exposure event: kV, mAs, anode, filtration, breast thickness, compression force
	III	Tomosynthesis exposure parameters (number of exposures, angle, kV, mAs, filtration)
Mobile fluoroscopy	I	Total KAP, total fluoroscopy time, and anatomical region (i.e., chest, abdomen, etc.)
	II	Total number of exposure events, fluoroscopy KAP, and radiography KAP Per each exposure event: kV, mA or mAs, frames/second, filtration, source–detector distance (SSD), fluoroscopy time, number of radiographic images, cumulative KERMA at reference point
	III	Source–skin distance (SSD)
Cone beam computed tomography	I, II, III	See “Digital radiography” (typically for dental CBCT) or “Angiography” section. Note that CBCT irradiation events must be clearly labeled as rotational events in the RDSR
