Proceedings ArticleDOI
Automatic lung segmentation in CT images using watershed transform
TL;DR: The proposed method eliminates the tasks of finding an optimal threshold and separating the attached left and right lungs, which are two common practices in most lung segmentation methods and require a significant amount of time.
Journal ArticleDOI
Deep Learning for Low-Dose CT Denoising Using Perceptual Loss and Edge Detection Layer
TL;DR: A deep neural network that uses dilated convolutions with different dilation rates instead of standard convolution helping to capture more contextual information in fewer layers is proposed and it is demonstrated that optimizing the network by a combination of mean-square error loss and perceptual loss preserves many structural details in the CT image.
Journal ArticleDOI
Automatic segmentation of cerebral MR images using artificial neural networks
TL;DR: The authors present an unsupervised clustering technique for multispectral segmentation of magnetic resonance (MR) images of the human brain using the Self Organizing Feature Map (SOFM) artificial neural network for feature mapping and generates a set of codebook vectors.
Journal ArticleDOI
Neural network based segmentation of magnetic resonance images of the brain
TL;DR: A study investigating the potential of artificial neural networks for the classification and segmentation of magnetic resonance (MR) images of the human brain shows that tissue segmentation using LVQ ANN also performs better and faster than that using back-propagation ANN.
Journal ArticleDOI
Development of a Nanoparticle-Labeled Microfluidic Immunoassay for Detection of Pathogenic Microorganisms
TL;DR: The microchannel immunoassays reliably detected H. pylori and E. coli O157:H7 antigens with biotinylated polyclonal antibodies in quantities on the order of 10 ng, which provides a sensitivity of detection comparable to those of conventional dot blot assays.
