The 182nd Meeting of the Acoustical Society of America (ASA) was held May 23–27, 2022, in Denver, Colorado. ASA holds two large meetings each year, and each features presentations on a wide variety of the scientific, medical, and industrial aspects of sound. The sessions that may be of particular interest to the focused ultrasound community are listed below and include bacterial infections, brain, cardiovascular, drug delivery, cancer immunotherapy, musculoskeletal, oncology, optic, renal, and technical applications.

Meaghan O’Reilly, PhD, a Senior Scientist at Sunnybrook Research Institute and Associate Professor of Medical Biophysics at the University of Toronto, received the R. Bruce Lindsay award for contributions to biomedical ultrasound applications in the central nervous system. This award is presented to an ASA member who has been active in the affairs of the society and has contributed substantially, through published papers, to the advancement of theoretical or applied acoustics, or both. Eligible members must be no more than 10 years post terminal degree at the time of award acceptance.

“Attending the ASA Denver meeting was a great experience,” said Dr. O’Reilly. “The R. Bruce Lindsay award brought great recognition to our work and more broadly to the field of focused ultrasound. There were many excellent presentations from those working in the focused ultrasound field, all of which were well received by the ASA community.”
