ULTRASOUND DIAGNOSTIC APPARATUS AND ATTENUATION MAP GENERATION METHOD

Abstract

A brightness average map and a brightness SD map are generated based on a first data group in a first region of interest. A first extraction process using a first threshold value and a second threshold value is applied to the brightness average map, and thus a first mask is generated. A second extraction process is applied to the brightness SD map, and thus a second mask is generated. An attenuation map is generated according to a composite mask based on the first mask and the second mask.
