Inserir no projetoP5942300Sistema de treinamento em codificação espacial na ressonância magnética nuclear

Principle

It should be demonstrated how spatial encoding does work in the MR technology. Experiments are executed with a MRT training device giving the opportunity ton investigate some small probes in the sample chamber. Device control is done with the provided software. Investigations comprise the generation of a 1D spatial encoding procedure via an additional magnetic field gradient in the driection of encoding and the visualizations of spatiotemporal T1- and T2-profiles. T1 and T2 are specific to the particular sample material and thus give important evidence for the composition of the subject of investigation. 

Tasks

1. 1D spatial encoding via a magnetic field gradient (frequency coding).
2. Visualization of spatiotemporal T1-profiles in spatial encoding direction.
3. Visualization of spatiotemporal T2-profiles in spatial encoding direction.
