Report

MR PWV tubular phantom study.

General Info

Phantom is a straight latex tube, approximate length 40cm, diameter 1cm, filled with water.


Pumping rate 75bpm.


MR venc 200.

Images

Phase Contrast (PC) image with calculated centerline and measuring positions equally spaced at 50mm apart (except for the last centerline section).

Charts

MR velocity curves for each sampling position (index numbers of curves and positions match).

Tables

MR Table of lengths, time shifts and PWV results between each of the positions given by their index numbers (shown in columns). Cross-correlation method was used to determine the time shifts.
