Abstract Text
In this lecture we will cover all the pulse sequences that we frequently use for radiotherapy planning (MR-sim) and online MR-guidance (MR-Linac). We will see how contrast is formed and how changes to the readout affect the geometric accuracy of our images. We’ll start easy by exploring standard T1- and T2-weighted sequences and increase complexity as we go along and discuss the inner workings of DWI, 4D-MRI, and real-time tumor tracking. We’ll end with a few research examples that show where the field is heading.
Learning objectives
- Understand how T1 and T2 contrast is generated
- Know how diffusion weighting is achieved
- Know that the imaging readout determines the geometric accuracy of the resulting images
- Learn how 4D-MRI is are acquired
