How Do MRI Machines Work? An Introduction to MRI and Open Source Imaging

Presented at A New HOPE (2022), July 23, 2022, 2 p.m. (50 minutes)

Superconducting, cryogenically cooled, terrifyingly strong magnets, bordering on perpetual motion; radio frequency (RF) coils big enough to crawl inside; fast switching, high power amplifiers to create hazardous levels of robot noises (and also flip around some magnetic fields). All in one giant Faraday cage. This talk will give a broad overview of the various technologies at work in a magnetic resonance imaging (MRI) machine, as well as highlight some of the work of the OpenSourceImaging.org community.

Presenters:

• Douglas Brantner
  **Douglas Brantner** is an MRI research engineer working on sensors, electronics, software, and simulations for MRI as well as ultrasound. He was inspired to change careers and go back to school several years ago at HOPE. In his brief time in this new field, he has already been co-author on two academic MRI conference presentations, one of which is now a project on OpenSourceImaging.com.
