CUDA-accelerated Python utilities for high-throughput PET/MR image reconstruction and analysis

NiftyPET: High-throughput image reconstruction and analysis

Documentation: https://niftypet.readthedocs.io

NiftyPET is a software platform and a Python namespace package encompassing sub-packages for high-throughput PET image reconstruction, manipulation, processing and analysis with high quantitative accuracy and precision. See below for the description of the above image, reconstructed using NiftyPET [*].

NiftyPET includes two packages:

• nimpa: https://github.com/NiftyPET/NIMPA (neuro-image manipulation, processing and analysis)

• nipet: https://github.com/NiftyPET/NIPET (quantitative PET neuro-image reconstruction)

The core routines are written in CUDA C and embedded in Python C extensions. The scientific aspects of this software platform are covered in two open-access publications:

• NiftyPET: a High-throughput Software Platform for High Quantitative Accuracy and Precision PET Imaging and Analysis Neuroinformatics (2018) 16:95. https://doi.org/10.1007/s12021-017-9352-y

• Rapid processing of PET list-mode data for efficient uncertainty estimation and data analysis Physics in Medicine & Biology (2016). https://doi.org/10.1088/0031-9155/61/13/N322

The above dynamic transaxial and coronal images show the activity of ¹⁸F-florbetapir during the one-hour dynamic acquisition. Note that the signal in the brain white matter dominates over the signal in the grey matter towards the end of the acquisition, which is a typical presentation of a negative amyloid beta (Abeta) scan.
