TL;DR: The reduced entropy of the first sinusoid formant of the heart sounds in children with PAH suggests the existence of an organized pattern, which could be applied to a noninvasive method to diagnose PAH.
Journal ArticleDOI
Photoacoustic and high-frequency power Doppler ultrasound biomicroscopy: a comparative study.
TL;DR: An imaging system for combined photoacoustic and high-frequency power Doppler ultrasound microscopy is presented and a combination of the two modes could provide improved estimates of fractional blood volume in comparison with either mode used alone.
Journal ArticleDOI
Dual-Frequency CMUT Arrays for Multiband Ultrasound Imaging Applications
TL;DR: In this article, a dual-frequency capacitive micromachined ultrasonic transducers (CMUTs) are introduced for multiscale imaging applications, where a single array transducer can be used for both deep low-resolution imaging and shallow high resolution imaging.
Proceedings ArticleDOI
CMUTs with improved electrical safety & minimal dielectric surface charging
TL;DR: In this article, a double SOI CMUT design was proposed to minimize surface roughness of the dielectric layer, which can minimize surface charge accumulation and provide maximum electrical safety to future patients.
