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.
