Amplified Magnetic Resonance Imaging
Amplified magnetic resonance imaging (aMRI) is an MRI method which is coupled with video magnification processing methods to amplify the subtle spatial variations in MRI scans, to enable better visualization of tissue motion. aMRI can enable better visualization of tissue motion to aid the ''in vivo'' assessment of the biomechanical response in pathology. It is thought to have potential for helping with diagnosing and monitoring a range of clinical implications in the brain and other organs, including in Chiari Malformation, brain injury, hydrocephalus, other conditions associated with abnormal intracranial pressure, cerebrovascular, and neurodegenerative disease. The aMRI method takes high temporal-resolution MRI data as input, applies a spatial decomposition, followed by temporal filtering and frequency-selective amplification of the MRI frames before synthesizing a motion-amplified MRI data set. This approach can reveal deformations of the brain parenchyma and displacements of ar ...
