  • Non-cartesian caipirinha
    Patent number: 8717020
    Abstract: Example systems, methods, and apparatus concern non-Cartesian CAIPIRINHA (Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration). One example parallel magnetic resonance imaging (pMRI) apparatus includes a radio frequency (RF) manipulation logic configured to control the pMRI apparatus to perform a non-Cartesian CAIPIRINHA acquisition process in which under-sampled data is acquired using a non-Cartesian (e.g., radial) pattern. The apparatus also includes a reconstruction logic configured to reconstruct the under-sampled data as a function of phase shift applied by the non-Cartesian CAIPIRINHA acquisition process and coil sensitivities acquired during the non-Cartesian CAIPIRINHA acquisition process.
    Type: Grant
