A collection of TensorFlow add-ons for computational MRI.

Project description

pypi build docs doi

TensorFlow MRI is a collection of TensorFlow add-ons for computational MRI.

It contains functionality including:

  • Estimation of coil sensitivity maps: Walsh’s method, Inati’s fast method and ESPIRiT.

  • Coil compression using singular value decomposition (SVD).

  • Image reconstruction operations: basic (FFT, NUFFT), parallel imaging (SENSE, GRAPPA, CG-SENSE) and partial Fourier (zero-filling, homodyne detection, projection onto convex sets).

  • Calculation of radial and spiral trajectories and sampling densities.

  • Keras metrics for image quality assessment, classification and segmentation.

  • Helper operations for array manipulation, image processing and linear algebra.

All operations are performed using a TensorFlow/Keras backend. This has several key advantages:

  • Seamless integration in machine learning applications.

  • Runs on heterogeneous systems, with most operations supporting CPU and GPU-accelerated paths.

  • Code is easy to understand, with most of this package written in Python.

Installation

You can install TensorFlow MRI with pip:

$ pip install tensorflow-mri
