photoacousticdynamic receive beamformingultrasound flash imagingin vivoPhotoacoustic imaging offers a new and complementary contrast mechanism to the traditional structural contrast of ultrasound. While the combination of these two modes has been demonstrated in the past with single-element transducers, array...
The combination of photoacoustic (PA) imaging and ultrasound localization microscopy (ULM) with microbubbles has great potential in various fields such as oncology, neuroscience, nephrology, and immunology. Here we developed an interleaved PA/fast ULM imaging technique that enables super-resolution vascula...
The saved beamformed data were exported to a personal computer to perform offline post-processing such as signal-to-noise ratio (SNR) calculation, maximum amplitude projection (MAP), or pixel intensity analysis. Figure 1. Photograph and schematic of dual-modal photoacoustic and ultrasound imaging ...
A volumetric noncontact ultrasound imaging method could resolve many existing limitations and extend ultrasound imaging to broader applications. As presented in this article, full noncontact laser ultrasound (LUS) – employing skin surface photoacoustic sources in combination with laser interferometric detection...
Digital beamforming has been widely used in modern medical ultrasound instruments. Flexibility is the key advantage of a digital beamformer over the tradit... P Chen,M Butts,B Budlong - Medical Imaging 被引量: 7发表: 2008年 Synthetic-aperture based photoacoustic re-beamforming (SPARE) approach...

We report a target-enclosing, hybrid tomograph with a total of 768 elements based on capacitive micromachined ultrasound transducer technology and providing fast, high-resolution 2-D/3-D photoacoustic and ultrasound tomography tailored to finger imaging. A freely programmable ultrasound beamforming ...
We present a method and setup that provide complementary three-dimensional (3D) images of blood oxygenation (via quantitative photoacoustic imaging) and blood flow dynamics (via ultrasound Doppler). The proposed approach is label-free and exploits blood-induced fluctuations, and is implemented on a ...
Ultrasound is an attractive imaging modality for guiding surgeries or minimally invasive interventions mainly because it is real time, safe, portable, and low cost. Further technological advancements in ultrasound instrumentation, such as further miniatu
