Abstract:
An ultrasound imaging phantom for use in quality assurance testing of ultrasound scanners, comprising:(a) an ultrasound phantom container;(b) a tissue mimicking background material contained within the phantom container;(c) a first section in the tissue mimicking background material having an array of coplanar target spheres embedded in the background material, wherein each target sphere is made of a tissue mimicking material, a second section in the background material having at least one target cylinder embedded in the background material, and a third section having a planar array of elongated fibers embedded in the background material, wherein the tissue mimicking material of the target spheres and target cylinders differs from the background material in which they are embedded by at least one of ultrasonic speed, backscatter coefficient or attenuation coefficient.
