IEEE IUS 2017 Recap

We just returned from a successful, invigorating, and inspiring IEEE International Ultrasonics Symposium (IUS) held in Washington, DC at the Omni Shoreham Hotel. Some photograph highlights of our involvement appear below.

Joshua Shubert presented his poster entitled “Photoacoustic Based Visual Servoing of Needle Tips to Improve Biopsy on Obese Patients

Derek Allman presented his poster entitled “A Machine Learning Method to Identify and Remove Reflection Artifacts in Photoacoustic Channel Data

Prof. Bell served on the 2017 IUS Organizing Committee as the Communications Chair. She received a certificate  from the UFFC Society President (Clark Nguyen, left) and Vice President for Ultrasonics (Jafar Saniie, right) in appreciation of her service.

Michelle Graham (photo unavailable) also presented her poster entitled “Theoretical Application of Short-Lag Spatial Coherence to Photoacoustic Imaging.”

PULSE Lab members additionally collaborated to contribute to the following papers:
