Many ultrasound researchers perform h ydrophone measurements\, but few are aware of the distortions that hydroph ones produce and the recently developed algorithms to correct for them.\n\ nThis tutorial will cover:\n1. Physics of hydrophone designs (e.g.\, membr ane\, needle\, capsule\, reflection-type fiber optic\, Fabry-Perot interfe rometric fiber optic)\,\n2. Hydrophone specifications (e.g.\, sensitivity\ , directivity\, effective sensitive element size)\,\n3. Pros and cons of t he various hydrophone designs for different applications\,\n4. Practical a dvice for water-tank measurements\,\n5. Deconvolution methods to remove pr essure measurement distortions due to frequencydependent sensitivity and s patial averaging artifacts.\n\nDr. Wear’s algorithms have been applied i n elastography\, ophthalmology\, cavitation monitoring\, high intensity th erapeutic ultrasound\, and transcranial neuromodulation. They have been in cluded in International Electrotechnical Commission standards and have bee n cited in official position statements by the American Institute of Ultra sound in Medicine and the International Transcranial Ultrasonic Stimulatio n Safety and Standards Consortium.\n\nBldg: Laboratoire d'Imagerie Bioméd icale\, 15 rue de l'école de médecine\, Paris\, Ile-de-France\, France LOCATION:Bldg: Laboratoire d'Imagerie Biomédicale\, 15 rue de l'école de médecine\, Paris\, Ile-de-France\, France ORGANIZER:lori.bridal@sorbonne-universite.fr SEQUENCE:14 SUMMARY:IEEE UFFC 2026 Distinguished Lecture\, Keith Wear\, PhD\, Professor Research Physicist\, US FDA URL;VALUE=URI:https://events.vtools.ieee.org/m/544482 X-ALT-DESC:Description: <br /><p>Measurement of Acoustic Pressure with Hydr ophones\, Keith Wear\, PhD\, Professor&nbsp\;Research Physicist\, US FDA</ p>\n<p>Accurate acoustic pressure measurements with hydrophones are critic al to demonstrate safety and effectiveness of ultrasound devices as well a s ensuring reproducibility of ultrasound experiments and treatments.
