Experimental Validation of k-Wave: Nonlinear Wave Propagation in Layered, Absorbing Fluid Media

DOI

The data was collected for characterisation of the source, a single element spherically focusing ultrasound transducer driven with a 4 cycle burst at 1.1 MHz (H151, Sonic Concepts), and validation of simulation of the source propagating into water at a number of different drive levels. Measurements were also made for experimental validation of simulation of a nonlinear ultrasound field propagating through planar and wedge shaped glycerol filled phantoms.

All measurements were made with a PVDF needle hydrophone in an automated scanning tank.

The study data contains 3 files: 1 containing measurements made in water, 1 with a planar glycerol filled phantom and 1 with a wedge shaped glycerol filled phantom.

File 1, medium: water only:

Axial scans cover 30 to 200 mm, lateral scans cover -20 to 20 mm.

1: XY planar scan for source characterisation at low drive level, measured at z = 40 mm over a 52 by 52 mm plane.

2 - 7: Axial scans from 30 to 200 mm, at the lowest drive level (as used in 1), 6 repeats. (Fig 2,3)

8: lateral scan, level 1 (Fig 2,3)

9-11: Axial scans, level 2 (Fig 3)

12-13: lateral scans level 2 (Fig 3)

14-16: axial scans level 3 (Fig 3)

17-18: lateral scans level 3 (Fig 3)

19-21: axial scans level 4 (Fig 3)

22-23: lateral scans level 4 (Fig 3)

24-26: Axial scans level 5 (Fig 3)

27-28: lateral scans level 5 (Fig 3)

29-33: axial scans level 6 (Figs 3, 4)

34-38: lateral scans level 6 (Figs 3, 4)

File 2: medium: water background with planar glycerol phantom

1: XZ planar scan from x = -20 mm to 20 mm, z = 60 to 200 mm (beyond phantom) (Figs 5-7)

File 3: medium: water background with wedge shaped glycerol phantom

1: XZ planar scan from x = -20 to 20 mm, z = 70 to 200 mm (beyond phantom) (Figs 8-10)
