Panoramic images providing a larger local overview of the internal urinary bladder wall can be used for documentation and surgery planning, as well as assist the re-identification of multi-focal tumors during a cystoscopy. In contrast to white light illumination, the photodynamic diagnosis (PDD) leads to an enhanced tissue contrast, resulting in a reddish fluorescence of malignant tissue excited by...
Multiplexed imaging and illumination have been used to recover enhanced arrays of intensity or spectral reflectance samples, per pixel. However, these arrays are often not the ultimate goal of a system, since the intensity is a result of underlying object characteristics, which interest the user. For example, spectral reflectance, emission or absorption distributions stem from an underlying mixture...
An improved design for fiber bundle fluorescence endomicroscopy is demonstrated. Scanned illumination and detection using coherent fiber bundles with 30,000 elements with 3 μm resolution enables high speed imaging with reduced pixel cross talk.
This paper presents an imaging technique for assessing the stimulation of H35 cells by TNF-alpha. Specifically, fluorescence from the stimulated cells is measured in order to produce intensity profiles that describe the dynamics of the NF-kappaB transcription factor. The approach offers a cost-effective, non-invasive and quantifiable alternative to traditional techniques used to acquire this intracellular...
The goal of this paper is to make a global study about the digital image color processing methods. We focus our analyses to the spectral images, CIE (International commission on illumination) illumination standards, high dynamic range image, color saturation, color brightening and white balancing. We take an image and we test flash and fluorescent illumination, then we make white balancing correction...
