Here, we report on novel push–pull D−π–A dyes specially designed for Gaussian-shaped, narrow-band absorption and the high photoelectric conversion. These p-type organic dyes work both as a color ...

Abstract: At the relatively low frequency of the P-band spaceborne SAR, the background ionosphere is no longer treated as time-invariant, together with the spatial variation in the background ...

Background/aims This study investigated the risk factors for epiretinal membrane (ERM) in eyes with primary rhegmatogenous retinal detachment (RRD) that received silicone oil (SO) tamponade. Methods ...

Application of narrow-band imaging (NBI) in colonoscopy visualises mucosal vascular networks in neoplastic lesions and may improve diagnostic accuracy. Aim: To compare the diagnostic efficacy of NBI ...

Detection rates are expected to improve with optimised visualisation methods. This prospective randomised study evaluated narrow-band imaging (NBI), a new technique that may enhance image contrast in ...

In a meta-analysis, Saw and coworkers compared trials on retina detachment surgery and found no clear evidence in favor for any technique. It seemed that too many aspects are important for the ...

SLB has launched Retina at-bit imaging to enable early identification of formation characteristics. Retina provides precise measurements at the point of first contact between the drill bit and the ...

Abstract: We report on fabrication of a smart glass type laser scanning system using 2D MEMS scanner for retinal imaging. A MEMS based scanner was used to miniaturize the system size to fit into a ...
