Inter-Slice Compression And Reconstruction Of Glioma Magnetic Resonance Imaging (Mri) Data Using Encoder-Decoder Neural Networks, Gavin Michael Karr

Graduate Theses - Electrical and Computer Engineering

Magnetic Resonance Imaging (MRI) scans of patients with brain tumors are an important source of pre-surgical medical information. These three-dimensional image volumes can be represented as a stack of two-dimensional image slices. The objective of this thesis is to compress the size of these image volumes by removing the odd-numbered slices and reconstruct the image volume using an encoder-decoder convolutional neural network. This neural network architecture is based on a modified form of the U-net segmentation network, which has been adjusted to allow for multiple image inputs and to support a network capable of generating new image slices.
