Detailed Description

Class to convert from DSC T2* curves to Delta R2* representation. This is an in-place method that permits toggling between representations.

Thanks to Emma Essock-Burns and Janine Lupo PhD, UCSF Department of Radiology and Biomedical Imaging for help implementing this class.

Change the representation between T2* and DR2* See reference2: ΔR2* = −ln(St/S0)/TE For now, set S0, to be the value at point 5 after magnetization has stabilized.
