This technology includes a system for automatic artifact-free measurement and visualization of tissue strain by MRI at native resolution. The investigation of regional soft tissue mechanical strain can serve as a unique indicator for different related disorders. For example, measurement of myocardial tissue during contraction can help calculate, track, and assess cardiac stress. Currently, methods such as tagging MRI (tMRI) are used for imaging soft tissue deformation. Despite being well validated, methods such as tMRI suffer from low spatial and temporal resolution. The current described technology obtains pixelwise native high-resolution imagery for strain-mapping using a deep learning convolutional neural network.
High-resolution imaging and analysis of tissue strain can be used to reduce the time to diagnosis and provide more informative information for the treatment of a variety of disorders, including:
- liver inflammation and fibrosis assessment
- heart strain, cardiac function early assessment
- brain damage and tumor detection
- tongue tumors and speech problems
This method provides for a high anatomic, functional, and temporal resolution of tissue strain and deformation with unprecedented clarity.
