This is an advanced medical imaging technology that generates MRI-quality images using only ultrasound. Utilizing techniques from the geosciences, this reconstruction technique determines the material properties of imaged tissues, including their stiffness and density. With this information, specific tissue types can be identified, enhancing diagnoses. The added benefits of ultrasoundbased methods have the potential to open up broader medical imaging applications due to their non-ionizing nature, the relative speed of image acquisition, and the lower costs compared with MRI.
