Project Description

• We are building a FOS library to do thermal noise reduction suited for Multi-echo acquisitions
• This will be a Python implementation of (Tensor Denoising of Multidimensional MRI Data - Olesen - 2023 - Magnetic Resonance in Medicine - Wiley Online Library). Working with python possibilitates future integration with TEDANA
• https://github.com/SPiN-Lab/ME-PCA

Goals for Brainhack Global

1-Create function that takes tensor and creates a sliding window for analysis 2-Create function that performs higher-order singular value decomposition (HOSVD) 3-Documentation for library
