CMRsim - Simulating CMR of Moving Objects

CMRsim is a simulation framework that features full Bloch simulations as well as analytical signal evaluations for moving objects with an easy-to-use API in Python. The computationally demanding calculations are implemented in TensorFlow2 and can be executed in CPU and GPU environments alike.

What makes CMRsim special?
+ Use of Bloch simulations as well as analytical signal equations.
+ Convenient support for moving particles.
+ Architecture that allows including your own simulation modules with ease.
+ Scalable to detailed time-resolved digital phantoms.

MRXCAT - Numerical CMR Phantoms

MRXCAT is a framework for numerical simulation of cardiac MR. It is based on the extended cardiac torso phantom (XCAT), which provides anatomical tissue masks and incorporates cardiac contraction and respiratory motion. MR properties such as tissue parameters, contrast and signal models, receive coils and noise are assigned in MATLAB.

MRXCAT is distributed in Matlab source code format to support reproducible research. Anyone is allowed to use MRXCAT original and/or modified software for non-commercial purposes. If you publish research using MRXCAT, please cite the MRXCAT publication.

MRXCAT 2.0 - Biophysical CMR Phantoms

MRXCAT 2.0 is an extension of the MRXCAT framework for cine images. It couples the extended cardiac torso phantom with an anatomical and a biophysical functional model of the left ventricle, enabling the simulation of both healthy and pathological cardiac function. MR tissue properties are assigned using a texturizer leading to realistic image appearance.

MRXCAT 2.0 is open source and anyone is allowed to use the original and/or modified software for non-commercial purposes. If you publish research using MRXCAT 2.0, please cite the MRXCAT 2.0 publication.
