Abstract

This paper discusses needs for tissue equivalent test objects for use in ultrasound quality control. Currently available test objects are useful for assessing specific aspects of an ultrasound imaging system such as depth calibration and B-scan registration accuracy. A phantom which yields scattered echo signals of a similar magnitude as detected in tissues and producing the same frequency dependent attenuation of the beam would be useful for scan uniformity checks, evaluation of swept gain settings, and possibly for gray scale checks. The phantom material would also be useful for measuring pulse-echo response profiles of ultrasonic transducers.
