clinical applications, but consensus test methods are needed to standardize performance …

Photoacoustic imaging (PAI) is an emerging hybrid imaging modality that combines high-
contrast optical imaging with high-spatial-resolution ultrasound imaging. PAI can provide a …

Optical endoscopy is the most commonly applied procedure for inspecting the
gastrointestinal (GI) tract, and it is based on different approaches and designs, from using a …

Photoacoustic (PA) imaging is hybrid imaging modality with good optical contrast and spatial
resolution. Portable, cost‐effective, smaller footprint light emitting diodes (LEDs) are rapidly …

Photoacoustic (PA) endoscopy (PAE) has exhibited potential for providing the
complementary contrast to available optical endoscopy methods, particularly for deep vessel …

Abstract Recent advances in Light Emitting Diode (LED) technology have enabled a more
affordable high frame rate photoacoustic imaging (PA) alternative to traditional laser-based …

Image performance in optoacoustic endoscopy depends markedly on the design of the
transducer employed. Ideally, high-resolution performance is required over an expanded …

The inadequacy of existing colorectal imaging tools has significantly obstructed the efficient
detection of colorectal cancer. To address this issue, this work presents the cross-scale …

Photoacoustic endomicroscopy (PAEM) is capable of imaging fine structures in digestive
tract. However, conventional PAEM employs a tightly focused laser beam to irradiate the …

We propose the development of a hybrid optical and optoacoustic endoscope for
esophageal tracking. The novel esophageal hybrid endoscope will have the ability to …
