In vivo bistatic dual-aperture ultrasound imaging and elastography of the abdominal aorta

open access: yesFrontiers in Physiology
Introduction: In this paper we introduce in vivo multi-aperture ultrasound imaging and elastography of the abdominal aorta. Monitoring of the geometry and growth of abdominal aortic aneurysms (AAA) is paramount for risk stratification and intervention ...

Numerical Study of Photoacoustic Pressure for Cancer Therapy

open access: yesApplied Sciences, 2016
A commonly used therapy for cancer is based on the necrosis of cells induced by heating through the illumination of nanoparticles embedded in cells. Recently, the photoacoustic pressure shock induced by the illumination pulse was proved and this points ...

Optoacoustic Imaging in Inflammation

open access: yesBiomedicines, 2021
Optoacoustic or photoacoustic imaging (OAI/PAI) is a technology which enables non-invasive visualization of laser-illuminated tissue by the detection of acoustic signals. The combination of “light in” and “sound out” offers unprecedented scalability with

Shape Optimization of an Open Photoacoustic Resonator

open access: yesApplied Sciences, 2021
Photoacoustic (PA) measurements with open resonators usually provide poor detection sensitivity due to signal leakage at the resonator opening. We have recently demonstrated three different approaches for modelling the photoacoustic signal of open ...

Off-axis photoacoustic microscopy [PDF]

open access: yesSPIE Proceedings, 2010
Photoacoustic microscopy (PAM) is a high-contrast, high-resolution imaging modality, used primarily for imaging hemoglobin and melanin. Important applications include mapping of the microvasculature and melanoma tumor margins. We demonstrate a novel PAM design that markedly simplifies the implementation by separating the optical illumination from the ...

On the feasibility of ultrasound Doppler-based personalized hemodynamic modeling of the abdominal aorta

open access: yesBioMedical Engineering OnLine
Background Personalized modeling is a promising tool to improve abdominal aortic aneurysm (AAA) rupture risk assessment. Computed tomography (CT) and quantitative flow (Q-flow) magnetic resonance imaging (MRI) are widely regarded as the gold standard for

Oxygen Saturation Imaging Using LED-Based Photoacoustic System

open access: yesSensors, 2021
Oxygen saturation imaging has potential in several preclinical and clinical applications. Dual-wavelength LED array-based photoacoustic oxygen saturation imaging can be an affordable solution in this case. For the translation of this technology, there is

Monolithic Double Resonator for Quartz Enhanced Photoacoustic Spectroscopy

open access: yesApplied Sciences, 2021
A new approach for Quartz Enhanced Photoacoustic Spectroscopy is presented, based on an acoustic excitation from the outside of the prongs of a quartz tuning fork, to increase the sensitivity of the sensor.
