A Comparison of Five Methods for Signal Intensity Standardization in MRI
A major problem in magnetic resonance imaging (MRI) is the lack of a pulse sequence dependent standardized intensity scale like the Hounsfield units in computed tomography. This af...

Synthetic MRI Signal Standardization: Application to Multi-atlas Analysis
From the image analysis perspective, a disadvantage of MRI is the lack of image intensity standardization. Differences in coil sensitivity, pulse sequence and acquisition parameter...
