Table 2.

Radiomics features were extracted with a fixed bin width 25 (default setting of the pyradiomics library). Each feature map had to be rescaled to enable a robust extraction of the parameters. Input value ranges of the throughflow, angle, wall parallelity degree, normalized helicity and vorticity feature maps are given in the first row. They are mapped to the output ranges shown in the second row.

	Throughflow (m/s)	Angle (${}^{\circ }$)	Wall parallelity degree	N-Helicity	Vorticity
$u$	$\alpha$	WPD	LNH	$\omega$
Input range	$[-6,6]$	$[-0,180]$	$[0,1]$	$[-1,1]$	$[-1,1]$
Output range	$[-2048,2047]$	$[0,4096]$	$[0,4096]$	$[-2048,2047]$	$[-2048,2047]$
