Low Field Fetal CINE Cardiac MRI

CINE fetal CMR at 0.55T Reconstruction with motion-correction and cardiac gating

Description

This repository contains code to reconstruct CINE fetal CMR at 0.55T at multiple spatial resolutions. First, real-time images are reconstructed for motion-correction and cardiac gating. Fetal cardiac CINEs are then reconstructed using the corrected data.

Requirements

The code was been tested on MATLAB R2019b 9.7.0.1296695 Update 4. Some functions are incompatible with older versions. For MEX-file compilation, a compatible compiler is required (https://www.mathworks.com/support/requirements/supported-compilers.html).

Installation

In MATLAB, download repository manually or by using:

 !git clone https://github.com/datta-g/LowField-Fetal-CINE-CMR.git
 cd LowField-Fetal-CINE-CMR
 run install.m

All required repositories will be merged and installed.

Usage

A brief demo script (fetal_cardiac_demo.m) is provided with sample test data. In this script, real-times are reconstructed. Motion correction and metric optimised gating a re performed. A cine reconstruction is then performed.

 run fetal_cardiac_demo.m
