Although the use of ultrasonic plane-wave transmissions rather than line-per-line focused
beam transmissions has been long studied in research, clinical application of this …

Fuelled by innovation, optical microscopy plays a critical role in the life sciences and
medicine, from basic discovery to clinical diagnostics. However, optical microscopy is limited …

Most of ultrasound medical imaging systems currently on the market implement standard
Delay and Sum (DAS) beamforming to form B-mode images. However, image resolution and …

The paper describes the use of synthetic aperture (SA) imaging in medical ultrasound. SA
imaging is a radical break with today's commercial systems, where the image is acquired …

Ultrasound imaging is one of the most important and widely used diagnostic tools in modern
medicine, second only to the conventional x-ray. Although considered a mature field …

Photoacoustic imaging (PAI) is an emerging medical imaging modality capable of providing
high spatial resolution of Ultrasound (US) imaging and high contrast of optical imaging …

Piezoelectric materials have dominated the ultrasonic transducer technology. Recently,
capacitive micromachined ultrasonic transducers (CMUTs) have emerged as an alternative …

Real-time ultrasonic imaging systems have been available for more than thirty years. During
this time much has occurred to the basic architecture and functions of these clinical systems …

This paper describes a new ultrasonic array imaging method for Non-Destructive Testing
(NDT) which is derived from the medical Plane Wave Imaging (PWI) technique. The …

A method for real-time three-dimensional (3-D) ultrasound imaging using a mechanically
scanned linear phased array is proposed. The high frame rate necessary for real-time …
