Photoacoustic (PA) imaging has become invaluable in preclinical and clinical research.
Endoscopic PA imaging in particular has been explored as a noninvasive imaging modality …

Gastroenterologists routinely use optical imaging and ultrasound for the minimally invasive
diagnosis and treatment of chronic inflammatory diseases and cancerous tumors in …

The addition of photoacoustic endoscopy to conventional endoscopic ultrasound offers
imaging capabilities that may improve diagnosis and clinical care of gastrointestinal tract …

There has been a long-standing expectation that the optical-resolution embodiment of
photoacoustic tomography could have a substantial impact on gastrointestinal endoscopy by …

Optical-resolution photoacoustic endoscopy (OR-PAE) has been proven to realize imaging
on the vascular network in the gastrointestinal (GI) tract with high sensitivity and spatial …

We report photoacoustic and ultrasonic endoscopic images of two intact rabbit esophagi. To
investigate the esophageal lumen structure and microvasculature, we performed in vivo and …

Abdominal surgeries carry considerable risk of gastrointestinal and intra-abdominal
hemorrhage, which could possibly cause patient death. Photoacoustic imaging is one …

METHODS We built up the acoustic resolution photoacoustic microscopy (AR-PAM) system
for imaging layered tissues, such as the stomach wall. A tunable dye laser system was …

Imaging based on photoacoustic effect relies on illuminating with short light pulses absorbed
by tissue absorbers, resulting in thermoelastic expansion, giving rise to ultrasonic waves …

Photoacoustic (PA) and ultrasonic (US) imaging are promising techniques for imaging
biological tissue and diagnosing internal organs. This paper presents a real-time PA and US …
