Background and activities
My research interests is targeted towards medical ultrasound imaging, a method where echoes from high-frequency sound waves emitted into the body can be used to make images and measure properties of tissue and blood flow. Ultrasound imaging technology has had a remarkable development in recent years, providing a basis for clearer images that can be used to obtain a more certain medical diagnosis in the future healthcare.
