TgtFreeHarmony: Target-Free MRI Harmonization Framework
A new MRI harmonization method called TgtFreeHarmony addresses domain shifts caused by variations in scan parameters, sequences, or hardware. Unlike existing approaches that require access to both source and target domain data during training or testing, TgtFreeHarmony operates in target-free scenarios. This eliminates the need for data sharing between institutions, thereby addressing patient privacy concerns and enabling practical clinical deployment. The framework aligns source domain images to the target domain while preserving biological information such as anatomical structures.
