Therapeutic ultrasound and microbubble technologies seek to drive systemically administered microbubbles into oscillations that safely manipulate tissue or release drugs. Such procedures often detect the unique acoustic emissions from microbubbles wi

The overlaying rib cage is a major hindrance in treating liver tumors with high intensity focused ultrasound (HIFU). The problems caused are overheating of the ribs due to its high ultrasonic absorption capability and degradation of the ultrasound in

The use of intravascular MRI imaging of vessels will provide high quality images for improved diagnosis and treatment. An intravascular MR receive coil provides high SNR because of proximity to the tissue but respiratory and cardiovascular motion may
