摘要： An imaging system includes: a transceiver cell for generating a pressure wave and converting an external pressure wave into an electrical signal; and a control unit for controlling an operation of the transceiver cell. The transceiver cell includes: a substrate; at least one membrane suspending from the substrate; and a plurality of transducer elements mounted on the at least one membrane. Each of the plurality of transducer elements has a bottom electrode, a piezoelectric layer on bottom electrode, and at least one top electrode on the piezoelectric layer. Each of the plurality of transducer element generates a bending moment in response to applying an electrical potential across the bottom electrode and the at least one top electrode and develops an electrical charge in response to a bending moment due to the external pressure wave.

摘要： Disclosed herein are computer-implemented medical ultrasound imaging methods, and systems for performing the methods, that comprise forming a first frame of an ultrasound image sequence with high image quality; forming at least one frame of the ultrasound image sequence with reduced image quality; forming a second frame of the ultrasound image sequence with high image quality; and improving the quality of the at least one frame of the ultrasound image sequence with reduced image quality using the first and/or the second frames of the ultrasound image sequence with high quality. In some cases, the improvement of the quality of the at least one frame of the ultrasound image sequence with reduced image quality is achieved by application of machine learning.
