Single-detector 3D optoacoustic tomography via coded spatial acoustic modulation.
2022 Communications Engineering Evgeny Hahamovich, Sagi Monin, Ahiad Levi, Yoav Hazan & Amir Rosenthal Abstract Optoacoustic tomography (OAT) is a hybrid imaging modality that combines optical excitation with ultrasound detection and enables high-resolution visualization of optical contrasts at tissue depths in which light is completely diffused. Despite its promise in numerous research and clinical applications, … Continue reading "Single-detector 3D optoacoustic tomography via coded spatial acoustic modulation."Read More »
Single pixel imaging at megahertz switching rates via cyclic Hadamard masks.
2021 nature communications AbstractOptical imaging is commonly performed with either a camera and wide-field illumination or with a single detector and a scanning collimated beam; unfortunately, these options do not exist at all wavelengths. Single-pixel imaging offers an alternative that can be performed with a single detector and wide-field illumination, potentially enabling imaging applications in … Continue reading "Single pixel imaging at megahertz switching rates via cyclic Hadamard masks."Read More »
Single-pixel imaging of dynamic objects using multi-frame motion estimation.
2021 Scientific Reports AbstractSingle-pixel imaging (SPI) enables the visualization of objects with a single detector by using a sequence of spatially modulated illumination patterns. For natural images, the number of illumination patterns may be smaller than the number of pixels when compressed-sensing algorithms are used. Nonetheless, the sequential nature of the SPI measurement requires that … Continue reading "Single-pixel imaging of dynamic objects using multi-frame motion estimation."Read More »
Ultrasound Detection Arrays Via Coded Hadamard Apertures.
© 2020 IEEE AbstractIn the medical fields, ultrasound detection is often performed with piezoelectric arrays that enable one to simultaneously map the acoustic fields at several positions. In this work, we develop a novel method for transforming a single-element ultrasound detector into an effective detectionarray by spatially filtering the incoming acoustic fields using a binary … Continue reading "Ultrasound Detection Arrays Via Coded Hadamard Apertures."Read More »
Ultrasound Detection Using Acoustic Apertures
source: © 2018 IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control Ultrasound detection is commonly performed by piezoelectric transducers that are optimized for a specific application. Since the piezoelectric technology is not configurable, transducers designed for one application may not be compatible with other applications. In addition, some designs of ultrasound transducers may be difficult … Continue reading "Ultrasound Detection Using Acoustic Apertures"Read More »
