We describe a 3-D multiline parallel beamforming scheme for real-time volumetric ultrasound imaging using a prototype matrix transesophageal echocardiography probe with diagonally diced elements and separated transmit and receive arrays. The elements in the smaller rectangular transmit array are directly wired to the ultrasound system. The...

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...

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...
