摘要：
The present invention relates to a method and apparatus for imaging the mechanical properties of the prostate of a patient non-invasively. The apparatus generally comprises a magnetic resonance scanner, a vibration assembly coupled to the perineal region of the patient, and a driver that drives the mechanical exciter. The method generally comprises positioning the vibration assembly against the perineal region of the patient, vibrating the mechanical exciter to cause deformational excitation of a tissue region contacted in the perineum, capturing a series of images in time (snapshots) of the tissue region using the MR scanner, and finally processing the displacement images to generate maps of mechanical properties of images tissue.
