System for Use in MR Imaging Using Tissue Mechanical Resonance |
摘要 |
A system for use in MR imaging using tissue mechanical resonance includes an external wave generator for generating mechanical waves for transmission through patient anatomy. An RF pulse generator generates an RF pulse for exciting nuclei magnetic moments at specific spin frequencies in a particular selected anatomical region of interest. A motion encoding gradient generator generates a motion encoding gradient magnetic field within a time duration of a read-out gradient and synchronized with generation of the mechanical waves. A data processor processes data derived from radio frequency signals resulting from nuclei spin frequencies responsive to the motion encoding gradient magnetic field to detect the mechanical waves propagating through the patient anatomy.
