Effect of angle of insonation on measured wall thickness of agar phantom. Excel spreadsheet containing raw data and graphs of lumen diameter and wall thickness in an agar phantom of type C. Test of each of four marked positions on measured IMT and lumen in a phantom artery of type C. A and C diagonally opposite and B and D diagonally opposite and perpendicular to A_C. Phantom turned through 90 degrees for each scan. Probe and settings left unchanged. Probe at 1.42 cm from leading edge of near wall of phantom. ROI optimised for analysis where possible (changed when bubbles in wall would affect analysis). Average of 49 frames analysed for each setting.
