Abstract
Magnetic resonance elastography pulse sequences for encoding position and motion of spins, and methods of using the pulse sequences are disclosed. The pulse sequences utilize imaging gradients, comprising a positive lobe and a negative lobe having non-symmetric amplitudes, to encode harmonic or wave motion within a specimen, such as tissue.
Claims13
A method for encoding motion within biological tissue comprising:
- generating an imaging gradient to encode the harmonic or wave motion within the tissue by simultaneously encoding position and motion, the imaging gradient comprising a positive lobe and a negative lobe;
- wherein the positive and negative lobes of the imaging gradient have non-symmetric amplitudes.
In a magnetic resonance elastography pulse sequence for encoding position and motion of spins in a specimen, an improvement comprising an imaging gradient comprising a positive lobe and a negative lobe, the positive and negative lobes of the imaging gradient having non-symmetric amplitudes.
