The International Society for Therapeutic Ultrasound (ISTU) is a non-profit organization founded in 2001 to increase and diffuse knowledge of therapeutic ultrasound to the scientific and medical community, and to facilitate the translation of therapeutic ultrasound techniques into the clinical area for the benefit of patients worldwide.

Registration and Abstract Submission will open on October 1, 2020.

We are pleased to announce the next International Symposium for Therapeutic Ultrasound will be held April 25 - 28, 2021 in Gyeongju, Korea.


If you had already registered to attend ISTU 2020, we will be moving all of the registrations over to the 2021 Meeting. All pricing for ISTU 2021 will remain the same, so your paid registration will carry over to next year and you won’t have to worry about registering again! If you are unable to join us for ISTU 2021 and would like a refund, please send your request over email to the ISTU Secretariat at

The Abstract Submission Website will reopen October 1, 2020. We want to thank all of the people that submitted abstracts for the 2020 meeting. ISTU will be releasing all of the abstracts received as many people may want to update or submit to another meeting. We will send out the ISTU 2021 Call for Abstracts in the Fall.
