MRI-PDQ:Phase Detection & Quantification

Features

• Detects magnetic dipoles in MRI datasets
• Automatically masks out noise by fitting magnitude image to Rician & Gaussian distribution
• Estimates magnetic dipole moment for detected dipoles
• Eliminates unreasonable dipole moments (e.g., too-weak dipoles found in noise, or too-strong dipoles found in air bubbles)
• Works with non-isotropic datasets
• Processes multiple datasets, comparing dipoles quantitatively across them
• Calculates number of dipoles vs. distance from regions of interest (ROIs)
• Experimental: Estimates iron content within magnetic dipoles
• Experimental: Registers dipoles between different time points
• Experimental: Estimates dipole movements between different time points
• Experimental: Estimate 'best-fit' sphere radius for each dipole.
• Advanced: Detection templates: Detect dipoles located off-center of voxel boundaries; Simulate randomly-distributed spins to eliminate aliasing.
