CMPUT 616 – Autumn 2018

Fundamentals of Medical Imaging

Friday 14h00 to 16h30 in CSC 2-49

 

 

 

 

 

General Description:

 

The course starts by reviewing signal processing theory with example from medical imaging. We will then study six general medical imaging modalities: projection radiography, computed tomography, magnetic resonance imaging, nuclear imaging, ultrasound, and confocal microscopy. The goal will be to understand these modalities in terms familiar to medical practitioners. Following the study of modalities, we will then review basic 3D image processing such as filtering, registration, segmentation, and data driven physical simulation. Flexibility exists for the instructor to vary the depth of each topic area after determining the general background and experience of the students.

Textbook:

 

The following textbook is used to provide both the engineering, mathematical, and physics background necessary for this course. I will lecture from the class notes but I will refer to the textbook from time to time and some of the assignment will be from the textbook.

Homework

Homework will generally be handed out during a lecture and will be due on the following week. Some parts of the homework may involve SLICER exercises. There will be 6 problem sets. Don't be misled by the relatively few points assigned to homework grades in the final grade calculation. While the grade that you get on your homework is at most a minor component of your final grade, working the problems is a crucial part of the learning process and will invariably have a major impact on your understanding of the material.

 

Course Project

There will be an individual semester project, culminating in a final 8 pages report in IEEE format and a 20 minutes presentation during a one day workshop in December. Progress and check points before the final due date will count toward the final grade.

 

Course Grade

The final grade for the course is based on our best assessment of your understanding of the material, as well as your commitment and participation. The SLICER project, problem sets, and the final projects are combined to give a final grade:
