Transcutaneous fluorescence spectroscopy as a tool for non-invasive monitoring of gut function: first clinical experiences

Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-13 (2020)

Gastro-intestinal function plays a vital role in conditions ranging from inflammatory bowel disease and HIV through to sepsis and malnutrition. However, the techniques that are currently used to assess gut function are either highly invasive or unrel

Deep Graph-Based Multimodal Feature Embedding for Endomicroscopy Image Retrieval

Autor: Yun Gu, Guang-Zhong Yang, Khushi Vyas, Jie Yang, Mali Shen

Publikováno v: IEEE transactions on neural networks and learning systems. 32(2)

Representation learning is a critical task for medical image analysis in computer-aided diagnosis. However, it is challenging to learn discriminative features due to the limited size of the data set and the lack of labels. In this article, we propose

Line scanning, fiber bundle fluorescence HiLo endomicroscopy with confocal slit detection

Autor: Guang-Zhong Yang, Khushi Vyas, Haojie Zhang

Publikováno v: Journal of Biomedical Optics

Fiber bundle fluorescence endomicroscopy is an effective method for in vivo imaging of biological tissue samples. Line-scanning confocal laser endomicroscopy realizes confocal imaging at a much higher frame rate compared to the point scanning system,
