1. In-Plane Motion Correction in Reconstruction of non-Cartesian 3D-functional MRI
University essay from Datorseende; Tekniska högskolanAbstract : When patients move during an MRI examination, severe artifacts arise in the reconstructed image and motion correction is therefore often desired. An in-plane motion correction algorithm suitable for PRESTO-CAN, a new 3D functional MRI method where sampling of k-space is radial in kx-direction and kz-direction and Cartesian in ky-direction, was implemented in this thesis work.

2. Improved Temporal Resolution Using Parallel Imaging in Radial-Cartesian 3D functional MRI
University essay from DatorseendeAbstract : MRI (Magnetic Resonance Imaging) is a medical imaging method that uses magnetic fields in order to retrieve images of the human body. This thesis revolves around a novel acquisition method of 3D fMRI (functional Magnetic Resonance Imaging) called PRESTO-CAN that uses a radial pattern in order to sample the (kx,kz)-plane of k-space (the frequency domain), and a Cartesian sample pattern in the ky-direction.

3. Method for Acquisition and Reconstruction of non-Cartesian 3-D fMRI
University essay from Bildbehandling; Tekniska högskolanAbstract : The PRESTO sequence is a well-known 3-D fMRI imaging sequence. In this sequence the echo planar imaging technique is merged with the echo-shift technique. This combination results in a very fast image acquisition, which is required for fMRI examinations of neural activation in the human brain. READ MORE
