PARALLEL MAGNETIC RESONANCE IMAGING WITH LOCALIZED ARRAYS AND SINC INTERPOLATION (PILARS) Conference Paper

abstract

• Large arrays with localized coil sensitivity make it possible to use parallel imaging to significantly accelerate MR imaging speed. However, the need for auto calibration signals limits the actual acceleration factors achievable with large arrays. This paper presents a novel method for parallel imaging with large arrays. The method uses Sinc kernels for k-space data interpolation that only requires one phase parameter to be estimated using a small size of calibration signals. Phantom experiments show that the new method can achieve higher actual acceleration factors with comparable reconstruction quality. 2011 IEEE.
