High resolution ultrasound and photoacoustic imaging of single cells
High resolution ultrasound and photoacoustic images of stained neutrophils, lymphocytes and monocytes from a blood smear were acquired using a combined acoustic/photoacoustic microscope. Photoacoustic images were created using a pulsed 532 nm laser that was coupled to a single mode fiber to produce output wavelengths from 532 nm to 620 nm via stimulated Raman scattering. The excitation waveleng...
متن کاملHigh-resolution ultrasound perfusion imaging of therapeutic angiogenesis.
OBJECTIVES The purpose of this study was to test the feasibility of contrast pulse sequence (CPS) ultrasound imaging for high-resolution perfusion imaging after gene transfer (GT) for therapeutic angiogenesis. BACKGROUND Imaging modalities capable of accurate and feasible perfusion measurement are essential for the preclinical and clinical development of therapeutic angiogenesis. However, cur...
متن کاملHigh-resolution ultrasound elasticity imaging to evaluate dialysis fistula stenosis.
Accurate, noninvasive characterization of arterial wall mechanics and detection of fibrotic vascular lesions could vastly improve the ability to predict patient response to local treatments such as angioplasty. Current imaging and other techniques for determining wall compliance rely on imprecise or indirect estimates of wall motion. This study used high-resolution ultrasound imaging with phase...
متن کاملNovel instrument for high-resolution ultrasound flow imaging
In multigate systems employed in Doppler flow-imaging detectable velocities [4] . Moreover, they generally do not allow equipment, the velocities of targets located at different ranges along flow dynamics to be studied in detail, since in most cases only the ultrasound beam axis are simultaneously detected. Typically, to the presence or absence of moving scatterers within a vessel can reduce th...
متن کاملMedian nerve imaging using high-resolution ultrasound in healthy subjects.
Although electroneuro- and electromyography are still the leading diagnostic methods for investigation of peripheral nerve function, they do not provide information on their morphology. This study was conducted to evaluate the suitability of ultrasonography in visualization of median nerve in healthy volunteers. Twenty-five asymptomatic volunteers (17 women and 8 men), age range 21-47 years, pa...
