Fetal XCMR v1.1 2019-01-28
============================================================
This package contains scripts designed to simulate fetal cardiac MRI data.

Example usage of the main script "Fetal_XCMR_Main.m" is demonstrated by two demos for Cartesian and Radial data acquisitions respectively contained in "Fetal_XCMR_Demo.m".

Updates
============================================================
Units are included for user-defined motion amplitudes.
filesep is used instead of "/" for mac-compatibility

Dependencies
============================================================
This code was tested in Matlab R2018a on a laptop with Windows 10

All code is self contained and subfunctions are located in the Utilities folder with the exception of the non-uniform fourier transform which is required for radial data generation and reconstruction. It can easily be implemented using the iGRASP code from Li Feng and Ricardo Otazo.

Generating new source images using XCAT
============================================================
Source images are included representing dynamic fetal cardiac and maternal respiratory (50 frames each).

XCAT is a separate software, which allows you to create additional volumes which could be used by Fetal XCMR
The XCAT software is available here: http://www.hopkinsradiology.org/DMIP/Research/xcat

Distributing Fetal XCMR
============================================================
Fetal XCMR source code is distributed as Matlab files to support its use for research purposes. Anyone is allowed to use the original and/or modified Fetal XCMR code for non-commercial purposes. If you publish research using Fetal XCMR, please cite the Fetal XCMR publication currently submitted to JCMR.
