Mutual radiation impedance of circular CMUTs on a cylinder
(IEEE, 2016)
In ultrasound imaging, cross coupling of transducer elements through the medium has significant effect on the frequency response, thus affecting the quality of the ultrasound image. In Side-Looking Intravascular Ultrasound ...
Equivalent circuit for capacitive micromachined ultrasonic transducers to predict anti-resonances
(Springer Nature, 2020-12)
Equivalent circuit models have been long used to evaluate the dynamics of the capacitive micromachined ultrasonic transducer (CMUT). An important parameter in the characterization of a CMUT is the anti-resonance frequency, ...
Portable low cost ultrasound imaging system
(IEEE, 2016)
The applications of ultrasound in medicine have been increasing in the last decade either in diagnostics or in treatments. Ultrasound is routinely used in clinical examinations, such as pregnancy exams. On the other hand, ...
Signal to noise ratio optimization for a CMUT based medical ultrasound imaging system
(IEEE, 2015)
CMUTs offers key performance benefits compared to their piezoelectric counterparts. However, CMUTs are not widely adopted in commercial ultrasound imaging systems due to low signal to noise ratio (SNR) in the obtained ...
Receive-noise analysis of capacitive micromachined ultrasonic transducers
(IEEE, 2016)
This paper presents an analysis of thermal (Johnson) noise received from the radiation medium by otherwise noiseless capacitive micromachined ultrasonic transducer (CMUT) membranes operating in their fundamental resonance ...
Vertical cavity capacitive transducer
(American Institute of Physics Inc., 2021-04-01)
The capacitive micromachined ultrasonic transducer (CMUT) has inherent advantages, such as larger bandwidth and monolithic integration capability with electronics, when compared to the piezoelectric transducer. The most ...
