Is a thin diameter ureteroscope feasible for image guided intravascular procedures?

Current Directions in Biomedical Engineering, 2020
Vascular endoscopic imaging is known for a long time but has never made its way into clinical routine. Reasons for that are the complexity, lack of low-cost portable systems, and the lack of suitable endoscopes providing high image quality with small ...

Use of Optical Coherence Tomography in Dentistry

International Journal of Dentistry, Volume 2023, Issue 1, 2023., 2023
Optical coherence tomography (OCT) is an optics‐based imaging technique, which may be called an “optical biopsy.” It can be used to acquire structural information about a tissue at a resolution comparable to histopathology. OCT is based on the principle of low‐coherence interferometry where near‐infrared (NIR) light is shown on a tissue sample and then

Cardiac Computed Tomography Assessment of the Variation of Papillary Muscle Morphology before Mitral Valve Surgery

Journal of Cardiac Surgery, Volume 2023, Issue 1, 2023., 2023
Background. The morphology of the papillary muscles of the left ventricle is highly variable. Few studies have investigated papillary muscle morphology using imaging. Objective. This study aimed to assess papillary muscle morphology with primary mitral regurgitation (MR) using cardiac computed tomography (CT). Methods.

Full‐Color Metaoptical Imaging in Visible Light

Advanced Photonics Research, Volume 3, Issue 5, May 2022., 2022
Meta‐optics has emerged as an attractive platform for miniaturizing imaging systems. Despite progress, the meta‐optical imaging systems suffer from strong chromatic aberrations. Herein, the challenges, progress, and opportunities on full‐color imaging using the visible light using meta‐optics are reviewed.
