Table 1.

Number of convolutional parameters in the networks used in our experiments.

Architecture	Params	Ex. time	Ex. time	Ex. time
	(millions)	Synthetic (s)	TOF MRA (s)	μCTA (s)
DeepVesselNet-FCN	0.05	13	13	4
DeepVesselNet-VNet	16.56	17	20	7
DeepVesselNet-UNet	4.45	13	14	4
VNet	22.89	23	26	11
UNet	7.41	17	19	6

For the purpose of comparison, the number of parameters stated here refers to only the convolutional layers in the various architectures. Ex. Time refers to the average time in seconds required to process one volume in the sythetic and MRA TOF datasets.
