Introduction to Magnetic Resonance Imaging

syllabus | textbook | projects

What makes magnetic resonance imaging (MRI) such a flexible and powerful medical imaging tool? What contrasts can MRI measure non-invasively in the human body, and how can this be done efficiently?

This course describes the basic hardware, acquisition, and reconstruction of MRI. Students gain a foundation in MRI physics and learn how these concepts impact image properties. Class project uses advanced MRI approaches in MATLAB to understand and optimize image design parameters.

BIM241

By the end of the course, students will be able to:

  1. Describe the basic hardware, acquisition, and reconstruction concepts of magnetic resonance imaging (MRI).
  2. Employ fundamental concepts of MRI physics to characterize and make predictions about image properties.
  3. Implement an advanced MRI acquisition or reconstruction approach in MATLAB to demonstrate the effect of optimizing design parameters.

T2 shuffling for multi-contrast spin echo MRI

Cheng Li, Henry Mai, Denise Zhong

T2 shuffle knee

 

slidesT2_Shuffling_report.pdf

The T2 shuffling method combines compressed sensing techniques with subspace selection to model T2 decay. This novel acquisition and reconstruction method recovers images at multiple T2 contrasts without significant blurring.

Rosette

 

Rosette_slides.pdf | Rosette_report.pdf

Rosettes are flower-like k-space trajectories that utilize frequent sampling of the center of k-space to reduce noise and produce diffuse aliasing artifacts.
