Comparative signal-to-noise analysis of fibre-optic based optical coherence tomography systems [PDF]
, 2005 Several optical coherence tomography ( OCT) systems are proposed using optical. fibre components and based around Fizeau sensing interferometers. The theoretical signal- to- noise ratio ( SNR) is calculated for each of the proposed configurations ...

Intelligent Continuum Micromachines in Complex Confined Spaces
SmartBot, EarlyView.The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

A Multi‐Sequence Adversarial Fusion U‐Net for Brain Tumor Image Segmentation
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.In the field of brain tumor image segmentation, in order to avoid the impact of insufficient number of training samples, the method of fusing multi‐modal MRI information before segmentation is widely used. However, when fusing different modal features, existing methods only add fixed weights to the features of each modality, resulting in insufficient ...

Advances in deep‐tissue fluorescence imaging through optical clearing: A review
VIEW, EarlyView.Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...
