Classification of CT Scan Images of Lungs Using Deep Convolutional Neural Network with External Shape-Based Features.

abstract：:Major problems in treating breast cancer are the early detection of tumors and accurate biopsy of small volumes of breast (mamma) tissue. This report presents an elastic registration algorithm of two x-ray mammograms and a corresponding magnetic resonance imaging (MRI) volume. To cope with the soft tissue deformation ...
