Radiation physics
The student can:
- Understanding of the different nuclear mechanisms that lead to nuclear radiation, decay series, radiometric quantities
- Able to read and extract data from nuclide cards and use these in simple calculations of the amount of a specific type of radiation
- Understanding of the interaction mechanisms (energy loss mechanisms) between nuclear (mainly neutrons and electrons/positrons) and high energy photon radiation with atoms
- Understanding of the different interaction cross-sections; able to use these to calculate beam energy, particle loss and distance travelled in matter
- Understanding the different definitions of physical dosimetric quantities and their interrelation; able to calculate the dosimetric quantities in various irradiation geometries
- Understanding of the principles of the functioning of the gamma camera and its use in SPECT and PET instrumentation; design aspects and quality parameters of this instrumentation
MRI physics
The student can
7. reconstruct how an imaging sequence in MRI manipulates the magnetization using their respective equations
8. discuss several possible contrasts that are possible in MRI and how to generate them
9. explain the use of quantitative imaging and its requirements
10. understand how measured signals are translated into images

The goal of this course is that students understand the physical background behind imaging modalities using radiation (e.g. X-ray, CT) and magnetism (MRI). With this knowledge they will know how to optimally use these modalities by taking into account their possibilities and limitations.
It is expected from the students that they already have a basic understanding of the imaging modalities that are treated in this course. The students should know how a signal from a human body is obtained using X-ray, CT, and MRI. During this course the students learn how to accurately model and describe the physical behavior of these machines.
The lectures on radiation physics will deal with safety and protection. By getting familiar with the extensive physics behind radiation, safe usage will be made understandable.
In the part of the course which handles MRI, students will become familiar with the possibilities of several different imaging sequences and the equations that describe their signal. By using equations, imaging can be optimized for specific purposes such as suppression or contrast enhancement. Next to that, students will be introduced to how these signals are transformed into clinical images.
