A three-dimensional model for quantitatively predicting the distribution of echo signal levels and the gray scale texture appearance of ultrasound B-mode images has been developed. The model computes time-dependent echo signal waveforms resulting from scattering of acoustic pulses by particles randomly distributed in an attenuating medium and tranforms these signals into a gray scale image. Previously it was found that image texture generated by the model corresponds qualitatively to that found experimentally in ultrasound images of tissue-mimicking phantoms. The dependence of the texture upon the depth of the region scanned and on the characteristics of the transducer-pulser-receiver system were demonstrated in earlier studies. The quantitative aspects of the model were tested by constructing and modeling a phantom in which the ultrasonic scattering properties are well-characterized. The phantom consists of a tissue-mimicking material whose attenuation coefficient is 0. 45 db/cm-MHz.
