Assignment to Modules

Further Information

Courses are together with exams the building blocks for modules. Please keep in mind that information on the contents, learning outcomes and, especially examination conditions are given on the module level only – see section "Assignment to Modules" above.

additional remarks This course is the first part of two lectures series, dealing with the physical principles of magnetic resonance imaging. The content of the first part focusses on the principles of magnetic resonance(MR) image formation. The lecture starts with addressing the question how an MR signal is generated, continues with the detection and manipulation of this signal and will finally cover the details how MR signals are processed into an image. Specifically, we will focus on: 1. Introduction to MRI 2. MR signal generation a. Magnetic moments b. RF excitation c. Signal detection 3. MR signal characteristics a. Free induction decay b. Spin echo c. Gradient echo 4. Spatial encoding of MR signals a. Slice selection b. Frequency and phase encoding c. k-space 5. Relaxation and image contrast a. Saturation-recovery sequence b. Inversion-recovery sequence c. Spin-echo sequence 6. Image reconstruction a. Basics of image reconstruction b. Reconstruction from Fourier samples 7. Image resolution and noise a. Resolution limitations b. Image Noise 8. Image artifacts a. Gibbs ringing b. Aliasing c. Chemical shift artifact d. Motion artifacts
