Brain palpation by using MR passive elastography
Code availability
Passive MRElastography.m:
This script processes a set of data, Raw_Data,
representing magnitude and phase acquisition in a human brain. It first unwraps
the MR Phase data and visualize the magnitude. Then the reconstruction pipeline
(wavelength_elastography) is performed to get the final
results and visualize the slices of the brain (magnitude and shear wavelength
maps: final_results). Requests for academic use of
in-house raw data can be addressed to the corresponding author. All requests
will be promptly reviewed to determine whether the request is subject to any
intellectual property or patient-confidentiality obligations, will be processed
in concordance with institutional and departmental guidelines and will require
a material transfer agreement.
Hardware Requirements
These two codes require only a standard computer with
enough RAM to support the in-memory operations. There is no requirement for
non-standard hardware.
Software Requirements
This package is supported for macOS and Windows. The
package has been tested on the following systems by using Matlab
2020:
Windows: Win 10
Demo availability
One example of brain MR acquisition for a patient with
a meningioma is proposed. You can load the calculation and the results through:
'Passive_MRElastography.m'.
The entire process takes less than 30s on a standard
computer.
Instructions for use
If you intend to utilize this tracking function with
your own dataset, it is crucial to adjust the defined parameters within the 'Passive_MRElastography.m' code to match the specifics of
your collected data.
Data example and codes
