Conversion of single-energy computed tomography to parametric maps of dual-energy computed tomography using convolutional neural network.

Abstract

We propose a deep learning (DL) multi-task learning framework using convolutional neural network (CNN) for a direct conversion of single-energy CT (SECT) to three different parametric maps of dual-energy CT (DECT): Virtual-monochromatic image (VMI), effective atomic number (EAN), and relative electron density (RED).
