A non-parametric vessel detection method for complex vascular structures
(ELSEVIER SCIENCE BV, 2009)
Modern medical imaging techniques enable the acquisition of in vivo high resolution images of the vascular system. Most common methods for the detection of vessels in these images, such as multiscale Hessian-based operators ...
A novel 19F agent for detection and quantification of human dendritic cells using magnetic resonance imaging
(Wiley, 2011-07)
Monitoring of cell therapeutics in vivo is of major importance to estimate its efficacy. Here, we present a novel intracellular label for 19F magnetic resonance imaging (MRI)-based cell tracking, which allows for noninvasive, ...
Optimized EDXRF system for simultaneous detection of gold and silver nanoparticles in tumor phantom
(Pergamon-Elsevier Science Ltd, 2019-12-24)
An energy-dispersive X-ray fluorescence system (EDXRF) was optimized for simultaneous detection of gold and silver nanoparticles inside water-equivalent phantoms applied to theranostics. The optimization process was carried ...
The 'sharpen' Filter Improves The Radiographic Detection Of Vertical Root Fractures
(WILEY-BLACKWELLHOBOKEN, 2015)
Assembly and characterization of a nonlinear optical microscopy for in vivo and ex vivo tissue imaging
(International Society for Optical Engineering - SPIEBellingham, 2014)
The purpose of this study is the assembly and characterization of a custom-made non-linear microscope. The microscope allows the adjustment for in vitro, in vivo and ex vivo imaging of biological samples. Two galvanometer ...
Automated analysis of leukocyte recruitment for in vivo studies using a spatiotemporal approach and multiple image features
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2020-03-30)
Over the last few years, many researchers have directed their efforts and interests toward in vivo studies of the cellular and molecular mechanisms in the microcirculation of many tissues under different inflammatory ...
In Vivo Detection of hESC-RPE Cells via Confocal Near-Infrared Fundus Reflectance
(Slack Inc, 2013-07-01)
BACKGROUND and OBJECTIVE: To investigate whether the confocal near-infrared reflectance (NIR) imaging modality could detect the in vivo presence of retinal pigment epithelium cells derived from embryonic human stem cells ...
Automated detection of photoreceptors in in-vivo retinal images
(Universidad Nacional de Colombia, 2016)
