Propeller/blade MRI with non-linear mapping to K-space |
摘要 |
A magnetic resonance imaging apparatus and method acquires NMR signal data for a periodically rotated data acquisition region in k-space wherein the acquisition region is caused to have non-linear acquisition loci. As an example, the width of the data acquisition region at a point distant from the origin of k-space is made larger than at a point nearer the origin of k-space thereby more fully filling k-space with acquired NMR data even if the number of RF pulse shots is reduced and/or the number of data acquisition region positions is reduce. A magnetic resonance image is reconstructed based on the acquired NMR signal data in k-space. |
