ABSTRACT:
An ultrasound phantom for use with an ultrasound scanner. The ultrasound phantom includes a container having a bottom and walls, margins of the walls remote from the bottom defining a window, which is closed by an ultrasound-transmitting window cover. A phantom body is contained within the container and includes a matrix made of a matrix material exhibiting a matrix ultrasonic speed, specific gravity, attenuation coefficient, and backscatter coefficient. The phantom body further includes a multiplicity of scattering particles spaced sufficiently close to each other that the scanner is incapable of resolving individual scattering particles and testing spheres having a testing sphere ultrasonic speed, specific gravity, attenuation coefficient, and backscatter coefficient, at least one of which is different from the corresponding matrix ultrasonic speed, specific gravity, attenuation coefficient, and backscatter coefficient. The testing spheres are located within the phantom body in a random array.
