A novel photoacoustic imaging system based on a semi-ring transducer array is proposed to
image peripheral blood vessels. The system's penetration depth is deep (∼ 15 mm) with …

Abstract Photoacoustic (PA) imaging (PAI) has been shown to be a promising tool for non-
invasive blood vessel imaging. A PAI system comprising a hemispherical detector array …

Photoacoustic imaging (PAI) with a linear-array-based probe can provide a convenient
means of imaging the human microcirculation within its native structural context and adds …

Slit‐based photoacoustic tomography is a newly developed technique that improves the
elevation numerical aperture of a linear array through acoustic diffraction. The slit, placed at …

Photoacoustic (PA) imaging provides unique advantages in peripheral vascular imaging
due to its high sensitivity to hemoglobin. Nevertheless, limitations associated with handheld …

Monitoring the blood supply in the lower extremities is critical for individuals who are
vulnerable to vascular dysfunction. Current clinical approaches are ineffective in observing …

One of the features of photoacoustic (PA) imaging is small-vessel visualization realized
without injection of a contrast agent or exposure to X-rays. For carrying out clinical studies in …

Slit-based photoacoustic tomography is a high-resolution three-dimensional imaging
technique for linear transducer array. The system was based on acoustic diffraction through …

Objective: In this study, we present the design, fabrication, and evaluation of a curved-array-
based photoacoustic imaging system designed for imaging vasculatures inside human …

Background: A breast-specific photoacoustic imaging (PAI) system prototype equipped with
a hemispherical detector array (HDA) has been reported as a promising system …
