Current Development and Applications of Super-Resolution Ultrasound Imaging

Abstract: Abnormal changes of the microvasculature are reported to be key evidence of the development of several critical diseases, including cancer, progressive kidney disease, and atherosclerotic plaque. Super-resolution ultrasound imaging is an emerging technology that can identify the microvasculature noninvasively, with unprecedented spatial resolution beyond the acoustic diffraction limit. Therefore, it is a promising approach for diagnosing and monitoring the development of diseases. In this review, we introduce … Show more

“…5d) . This is an important challenge in non-invasive, deep tissue imaging of tissue mechanics as it is well-documented that motion artifacts of live animals reduce accuracy and sensitivity 43 . We administered 100 µL MGVs at 2.28 nM into the tail veins of mice, and 5 min later performed MMUS imaging to image their delivery into the liver while animals were being anesthetized.…”

“…Such improvements have brought important benefits in various imaging applications. It is worth recalling that ultrasound super-resolution is an emerging technique proposed to visualize vascular tissue and atherosclerotic regions with a spatial resolution beyond the acoustic diffraction limit [2,3]. Multi-frequency transducers have opened to superharmonic imaging to become a reality thanks to the possibility to receive signal from the nonlinear response of microbubble at high-order harmonics using high-frequency transducers [4].…”

“…Having a high density (~5.8 g/cm 3 ) and effective atomic number (Z eff~5 0), CZT semiconductors confer a high attenuation power on incident radiations. They have a high energy resolution (<6% FWHM) compared to traditional NaI (~10% FWHM): this reduces the detection of scattering events, increasing the contrast-to-noise ratio (CNR) and spatial resolution.…”

“…providing full complex spectral field knowledge 24 . The scientific question is whether a THz-TDS can be exploited to develop a deterministic approach to waveform synthesis (closely related to ultrasound or radiofrequency approaches 25,26 ). The idea is to extract sufficient information to obtain access to any scattering-allowed output field.…”
