Modeling nonlinear propagation of ultrasound through inhomogeneous biomedical media

The design and optimization of medical ultrasound modalities require a method for modeling the propagation of pressure wave fields through biomedical tissue. This method needs to be capable of modeling various phenomena, e.g. nonlinear propagation, attenuation, and scattering caused by arbitrary inhomogeneities in the acoustic properties of the...

Multiline 3D beamforming using micro-beamformed datasets for pediatric transesophageal echocardiography

Until now, no matrix transducer has been realized for 3D transesophageal echocardiography (TEE) in pediatric patients. In 3D TEE with a matrix transducer, the biggest challenges are to connect a large number of elements to a standard ultrasound system, and to achieve a high volume rate (>200 Hz). To address these issues, we have recently...
