Summary and Setup
| Date | Friday 25th July 2025 |
| Time | 1:00 - 5:00 PM Eastern Daylight Time |
| Location | Westin Harbour Castle, Pier 7&8 - Toronto, Canada |
| Format | In-person workshop |
The workshop will provide practical information and an enhanced understanding on how to work with and analyze medical imaging data from magnetic resonance imaging (MRI) and positron imaging tomography (PET).
The initial portion of the workshop will focus on understanding the basic structure of an image, how to traverse images, data extraction, and how voxels relate to world coordinates.
Subsequent lectures will be followed by interactive sessions to demonstrate simple workflows including tissue segmentation, registration, and pre-processing steps for fMRI, DTI, and PET. The objective of the workshop is to ensure participants gain an in-depth appreciation of commonly used interpretive clinical and or research applications for each methodology.
This workshop uses virtual machines in the cloud. For more information on using the virtual machine for this immersive, please visit the following page:

Target Audience
This hands-on workshop can serve as a beginner or refresher course for established investigators, clinicians, and trainees involved in using imaging techniques to study Alzheimer’s disease, related disorders and normal ageing. Participants from any career stage are encouraged to join, including undergraduate students, graduate students, post-doctoral researchers and assistant professors engaged in clinical practice, research or teaching.
Requirements
Registrants must bring their own laptops to do the exercises (tablets or smartphones will not be sufficient). You will be provided with this repository and links to the “Basics of Neuroimaging” series of AAIC webinars. To get the most out of this workshop, we strongly recommend that you watch these webinars ahead of time. The links to the webinars and the slides are below.
At the workshop, we will all be using a standard environment, using a virtual machine (VM) hosted on the cloud. This ensures that everyone will be seeing the exact same screen for these lessons, regardless of if you are using a Mac or Windows operating system. You can find out more how to access this virtual machine below.
We will be using a Linux terminal to enter commands on the Unix shell. Before attending the session, you may want to familiarize yourself with the shell by running through the Command line lesson
Agenda
The workshop will consist of hands-on interactive sessions. The first session will focus on understanding the basic structure of imaging data, how to traverse images, data extraction, and how voxels relate to world coordinates. We will then go through the basic processing steps involving structural MRI data, demonstrating simple workflows including tissue segmentation, and registration.
The second half will consist of two independent working sessions, where facilitators will present interactive tutorials around different forms of neuroimaging analysis (structural MRI, fMRI, DTI or PET data), and the participants will then work on the tutorials of their choice, with assistance from the facilitators. The objective of the workshop is to ensure participants gain an understanding of how to start processing and analyzing various imaging modalities used in dementia research.
