Significance Various peripheral vascular diseases (PVD) in extremities, such as arterial
atherosclerosis or venous occlusion in arm or legs, are a serious global health threat …

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 …

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 …

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

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 …

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 …

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 …

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

For early diagnosis of rheumatoid arthritis (RA), it is important to visualize its potential
marker, vascularization in the synovial membrane of the finger joints. Photoacoustic (PA) …

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 …
