Design of a micro-beamformer for a 2D piezoelectric ultrasound transducer
TLDR
This paper describes the design of a transesophageal probe using a matrix (2D array) ultrasonic transducer for 3D echocardiography using a micro-beamforming method called pre-steering to reduce the complexity of the electronics and the channel count, while maintaining an adequate receive field.

Blood velocity estimation with high frequency intravascular ultrasound
When a cluster of randomly distributed blood particles moves across the ultrasound beam, the received echo signals decorrelate as a function of time. This phenomenon may be used to estimate the flowExpand
