Abstract

An image processing method for separating absorption and scatter components of ultrasonic attenuation CT (computer tomography) images is presented. The processing scheme involves the use of a previously developed theoretical model in conjunction with a speed tomogram to determine the spatial distribution of scattering-attenuation. This component when removed from the attenuation image yields an absorption-weighted image. Application of the proposed method to ultrasonic CT images of the breast was found to enhance the image quality considerably.
