To characterize su ch variations\, we have been developing imaging and measurement techniques based mainly on ultrasound. This presentation will introduce our recent s tudies on the visualization and characterization of heterogeneous material s from the surface to the interior. High-frequency ultrasonic imaging is u sed to obtain acoustic parameters such as sound velocity and attenuation. In elastography and optical coherence tomography (OCT)-based strain imagin g\, mechanical stimuli are applied to evaluate local mechanical heterogene ity. These approaches are applied to a wide range of heterogeneous materia ls\, including minerals\, soils\, food materials\, and biological tissues. Through these studies\, we aim to establish an Acoustic Morphology framew ork that describes material states and spatial heterogeneity by integratin g acoustic\, mechanical\, and structural information.\n\nSpeaker(s): Dr. M arie Tabaru\, \n\nRoom: 4463 ME (MakerLab)\, Bldg: Mackenzie Building\, Ca rleton University\, 1125 Colonel By Drive\, Ottawa\, Ontario\, Canada\, K1 S 5B6 LOCATION:Room: 4463 ME (MakerLab)\, Bldg: Mackenzie Building\, Carleton Uni versity\, 1125 Colonel By Drive\, Ottawa\, Ontario\, Canada\, K1S 5B6 ORGANIZER:yuuono@sce.carleton.ca SEQUENCE:13 SUMMARY:Acoustic Morphology: Elasticity Imaging and Characterization of Het erogeneous Materials URL;VALUE=URI:https://events.vtools.ieee.org/m/582618 X-ALT-DESC:Description: <br /><p>Heterogeneous materials often exhibit spat ial variations in structure\, mechanical properties\, and acoustic respons e.
