MRI Safety Training

Safety Training is required for anyone who uses the MRI scanner or works on any aspect of a project at the Imaging Center (including, for example, research assistants who look after participants waiting to be scanned). This regularly scheduled course is taught in a single session. Please email [Imaging Center Secretary] if you have any questions. Memorize the contents of this short safety document (PDF here) before coming to training.

MRI Operator Training

We encourage regular users of the scanner to become Scanner Operators where possible. This has the advantage of saving on the cost of hiring an operator and can increase scanning flexibility and efficiency.

In order to become a Scanner Operator at the SDSU Imaging Center, an Safety Trained individual must complete operator training with an Operator Trainer. The process involves not only learning how to safely put subjects into the scanner and operate the scanner console computer, but also becoming familiar with Imaging Center equipment, emergency procedures, and data transfer. On average, training lasts approximately 20 hours. Until complete, trainees are not allowed to operate the scanner without the assistance of an Operator Trainer.

First, identify an Operator Trainer who is willing to help you. Ask [Imaging Center Secretary] for a list of people who currently have a trainer account at the Imaging Center. This person is then responsible for ensuring the completeness of your training, although other trainers may also contribute. Once the trainer has agreed, the Principal Investigator on your project needs to send an email to Marty Sereno (msereno at and [Imaging Center Secretary], cc'ing your main trainer to confirm that they are happy for you to start the training, that they understand the procedures.

This one-on-one training begins by observing the trainer while they scan and explain what they are doing. The trainee then immediately takes over scanning operations under supervision of the trainer. Once the trainer thinks you are ready, you will act as an operator, with the trainer present to field questions. In the early stages of operator training, it is most efficient if experiments being run are thoroughly piloted and debugged (sequences, stimulus software), or if someone else (not you or your operator trainer) takes care of running the stimulus, so you can focus on first learning how to run the scanner.

Efficient scanning involves short periods intensive task-switching (setting up the next pulse sequence, while talking to the subject, and simultaneously readying the stimulus software), followed by long boring stretches of listening to scanner.

When the trainer feels that the trainee is ready, the trainer and trainee contact Marty Sereno for a final training session, to make sure that all of the trainee's questions are addressed and that they demonstrate confidence and security in all aspects of scanner operation. After passing this final 'drivers test', the trainee will be entered as an official Scanner Operator.

Neuroscience and Neuroimaging Courses

Two SDSU semester courses (upper level undergraduate, core graduate) that provide background in neuroscience and neuroimaging physics are taught in alternate semesters by Marty Sereno. Here are the most recent class web pages:

Foundations of Neuroimaging (PSY 596 — Fall 2017)
Systems Neuroscience (SCI 596 — Spring 2018)

Complete lecture recordings (using the SDSU Learning Glass) hosted by MediaSite are publicly accessible from these pages:
