Diffusion Measurements - DWI
The following diffusions measurements were aquired using a DWI sequence referring to the following two publications:
Sequences for Diffusion MRI
Jim Pipe, Ph.D., St. Joseph’s Hospital, Phoenix, Arizona, USA
The Stejskal–Tanner equation generalized for any gradient shape - an overview of most pulse sequences measuring free diffusion
Davy Sinnaeve - Department of Organic Chemistry, Ghent University, Belgium
The figure below shows the used sequence programmed in the openMATLAB interface. The DWI sequence can be configured to use multiple diffusion and imaging modules in 0D / 1D and 2D.
As a demonstration we measured the ADC values of a selection of oils: rapeseed oil, olive oil and sewing machine oil. This is shown in the left figure.
The ADC values of a combined sample of ethanol and water is shown in the right figure.
