The aim is to demonstrate and investigate how spatial coding works in MR technology. The experiments are carried out using the MRI training device, which allows smaller samples to be examined directly in a sample chamber. The device is controlled using the software supplied. The investigations include the generation of 1D spatial encoding by means of an additional magnetic gradient field in the encoding direction and the visualisation of spatio-temporal T1 and T2 profiles. T1 and T2 are specific to the sample material under investigation and therefore provide important information about its characteristic composition.
