When isotopes of the same element are present, like for Xe or Ge, the vmin
intervals of the different isotopes almost completely overlap, and we take [v.sub.min,1] and [v.sub.min,2] to be the [C.sub.T]-weighted averages over the isotopes of the element.
In all study patients, blood flow parameters in right and left eyes were assessed (maximum velocity Vmax, minimum velocity Vmin
, mean velocity Vm, resistive index RI and pulsatility index PI) in the short posterior ciliary arteries of the temporal optic disc, by color Doppler imaging in projection B using Toshiba Aplio SSA 770A with a linear probe of 14.0 MHz.
Besides peak and average the list of automatic measurement functions includes: Vpp, Vmax, Vmin
