Her mite-scan (H-scan) imaging is a new approach for characterizing tissue str uctures based on color-mapping of scatterer sizes. In H-scan imaging\, rad iofrequency (RF) echoes are matched to Gaussian-weighted Hermite polynomia ls of order n\, which are related to the size of scatterers. Furthermore\, shear wave viscoelastography exploits the shear wave generated by an ultr asound beam and extracts the viscoelastic properties of tissues from the f requency dependence of the measured wave velocity. In this talk\, I will d emonstrate the feasibility of differentiating glioblastoma tumors from nor mal brain tissue ex vivo using H-scan imaging\, with potential application s in intraoperative brain tumor imaging. I will also discuss our work on v alidating shear wave viscoelastography on viscoelastic tissue-mimicking ph antoms.\n\nSpeaker(s): \, Dr. Karla Mercado-Shekhar\n\nVirtual: https://ev ents.vtools.ieee.org/m/366813 LOCATION:Virtual: https://events.vtools.ieee.org/m/366813 ORGANIZER:ieee.cs.sbc.iit.kgp@gmail.com SEQUENCE:12 SUMMARY:Enabling techniques for tissue characterization using ultrasound He rmite-scan imaging and shear wave viscoelastography URL;VALUE=URI:https://events.vtools.ieee.org/m/366813 X-ALT-DESC:Description: <br /><p><span style="font-weight: 400\;">Ultrasoun d is rapidly evolving and can now provide information about tissue structu re and stiffness for enabling objective diagnosis.

Furthermore\, shear wave viscoela stography exploits the shear wave generated by an ultrasound beam and extr acts the viscoelastic properties of tissues from the frequency dependence of the measured wave velocity. In this talk\, I will demonstrate the feasi bility of differentiating glioblastoma tumors from normal brain tissue ex vivo using H-scan imaging\, with potential applications in intraoperative brain tumor imaging. I will also discuss our work on validating shear wave viscoelastography on viscoelastic tissue-mimicking phantoms. </span></p>\ n<p>&nbsp\;</p> END:VEVENT END:VCALENDAR
