Content, Learning Outcome and Preconditions
This module builds up upon module PH2270. It starts with an in-depth look at the connected areas of sampling and reconstruction of MR signals, from which general results about the achievable resolution and the propagation of noise can be obtained. After presenting typical artifacts and their origins, we conclude with a survey of actual rapid imaging techniques.
· Sampling of k-Space
o The Sampling Theorem
o Sampling Requirements of k-Space Signals
· Image Reconstruction
o General Issues
o Reconstruction from Fourier Transform Samples
· Resolution, Noise and Artifacts
o Point Spread Function
o Image Noise
o Image Artifacts
· Rapid Imaging Techniques
o Spin Echo based
o Gradient Echo based
o Echo Planar Imaging
After successful participation in this module the students are able to:
- describe the general approach to and interdependency of signal sampling and image reconstruction.
- understand, how image quality (resolution, SNR, artifacts) is affected by specific boundary conditions of signal sampling and reconstruction.
- describe the most relevant rapid imaging techniques.

Learning and Teaching Methods
This module consists of a lecture and an exercise class.
The teaching methods are: Oral presentation, Quiz, Exercises, Discussions. Physics of Magnetic Resonance Imaging 2 has 4 homework problem sets. Homework will be handed at the end of selected lectures. In the beginning of the next lecture, the students are able to hand in their solutions, which will not be graded. The solutions of the homework problems will be discussed in class during the first hours of the class when the homework is due.

Description of exams and course work
There will be a written exam of 60 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
- Explain the connection between sampled k-space and the resulting reconstructed resolution.
- Name a few typical artifacts and explain their respective causes.
- Which rapid imaging sequences are well-suited for T1-weighted abdominal imaging?
In the exam no learning aids are permitted.
There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of handing in at least 3 out of 4 homework set sheets.
The exam may be repeated at the end of the semester.
