DUG-RECON: A Framework for Direct Image Reconstruction Using Convolutional Generative Networks

نویسندگان

چکیده

This article explores convolutional generative networks as an alternative to iterative reconstruction algorithms in medical image reconstruction. The task of involves mapping projection domain data collected from the detector domain. is done typically through which are time consuming and computationally expensive. Trained deep learning provide faster outputs proven various tasks across computer vision. In this work, we propose a direct framework exclusively with architectures. proposed consists three segments, namely, denoising, reconstruction, super resolution (SR). denoising SR segments act processing steps. segment novel double U-Net generator (DUG) learns sinogram-to-image transformation. entire network was trained on positron emission tomography (PET) computed (CT) images. approximates 2-D architecture proof-of-concept work approach reconstruction; further improvement required implement it clinical setting.

Convolutional Recurrent Neural Networks for Dynamic MR Image Reconstruction

Accelerating the data acquisition of dynamic magnetic resonance imaging (MRI) leads to a challenging ill-posed inverse problem, which has received great interest from both the signal processing and machine learning communities over the last decades. The key ingredient to the problem is how to exploit the temporal correlations of the MR sequence to resolve aliasing artefacts. Traditionally, such...

Using Convolutional Neural Networks for Image Recognition

A neural network is a system of interconnected artificial “neurons” that exchange messages between each other. The connections have numeric weights that are tuned during the training process, so that a properly trained network will respond correctly when presented with an image or pattern to recognize. The network consists of multiple layers of feature-detecting “neurons”. Each layer has many n...
