In the conversion signal to concentration methods, the option of T1-map conversion is given. However, currently only a specific method using variable flip angles is implemented. This is not clear from the naming and the following labels need to be renamed for clarity: "Using T1-map" will be renamed to "Using T1 Map Via Variable Flip Angle" and "T1-map [ms]" will be renamed to "Proton Density Weighted Image".
