Abstract

In order to decrease artifacts from tissue, contrast enhanced perfusion imaging is usually conducted using low transmit power (low MI). However, with low MI echo signals from deeper structures are weak and often miss higher harmonics due to attenuation. Furthermore, shadowing artifacts may occur as a result of high concentration of contrast agent. Imaging an object (e.g. female breast) from multiple angles of view (spatial compounding) may overcome this issue. In addition, spatial compounding achieves an isotropic resolution and reduces speckle and further common artifacts. Here, first in-vitro results of contrast enhanced spatial compounding are presented
