Image reconstruction from non-Cartesian k-space data acquired by ultra-short echo-time and fast MR imaging methods
Pšorn, Tomáš ; Latta,, Peter (oponent) ; Starčuk, Zenon (vedoucí práce)
The aim of this thesis is to handle theoretically the technique of MRI image reconstruction from non-Cartesian data such as radial, spiral, etc. Since later progress of this thesis will include actual measuring of non-Cartesian data, which is prone to the gradient infidelity, methods for measuring a performance of the gradient system will also be discussed. In practical part I will present the way the 4.7 T and 9.4~T MRI systems of the Institute of Scientific Instruments of the ASCR, v. v. i., works and use the existing pulse sequences to measure some model data.
