Matthew McGarry

Overview

Matt grew up in Nelson, New Zealand, and studied mechanical engineering for his BE and Master's degrees at the University of Canterbury. His PhD at Thayer focused on improving and evaluating an inverse problem formulation for magnetic resonance elastography, where the mechanical properties of tissue are mapped to diagnose and monitor a wide range of diseases. He has also worked in ultrasound imaging of arteries and a range of cancers.

• Magnetic resonance elastography

  Magnetic resonance elastography

  Magnetic resonance elastography is being developed as a technique to measure the elasticity of tissue in vivo by gently shaking the tissue in a magnetic resonance imager. The displacements measured are used to determine tissue mechanical properties which can help identify and classify breast lesions. See also Discovering at Thayer School.
