Bioe225/Rad225: Intro to Ultrasound Physics and Ultrasound Neuromodulation

alt text 



General Course Description

Goals of the course

  • to learn the fundamentals of ultrasound physics, as needed for ultrasound neuromodulation

  • to learn the fundamentals of ultrasound neuromodulation physiology

Changes from Prior Years

  • We won't be covering ultrasound imaging. This means that we won't be covering the receive side of ultrasound. All the transmit concepts that we cover are the same as for diagnostic imaging, so those concepts carry over to diagnostic imaging. We also won't be covering as many applications of therapeutic ultrasound as we did last year.

Time and Location

  • Recordings of the lectures will be available for asynchronous viewing.

  • In general, Mondays and Wednesdays will be TA sessions and optional. However, on the first Monday, Kim will be available to answer questions about the class. On the first Wednesday, Emily will be available to provide an introduction to Matlab.

  • There will be a discussion session on Fridays at 4 that will cover the lectures of that week.

  • The live sessions will meet by Zoom. The link is to be announced. If you would like to audit the course and get access to the recordings, please email Kim.

Course Overview

  • Lectures will be posted by the dates indicated in the outline. Students will learn the material in the lectures and come prepared to discuss at Friday discussion sessions. Each Friday discussion will cover the material in that week. Students should submit 3 questions to Kim by Friday morning 9 am. Guest speakers will be invited to come to these discussion sessions.

  • Homeworks will cover mostly physics material. Homeworks will be due on Wednesdays. Emily will have TA sessions on Mondays and Wednesdays at 4 pm. The physics homeworks will extend throughout the quarter, even as the lecture material will move to biological effects of ultrasound on the brain. In the last few weeks, homeworks will give way to a project to be presented to the class at the end of the quarter. Students will have a choice of projects.


  • College level physics.

  • College level biology.

  • Some experience with Matlab or willingness to learn. Emily will have an intro to Matlab session in the beginning of the quarter.

Course Materials

  • All course materials will be made available through Canvas. We are currently setting this up.
