![]() The quality of the reconstructed image is evaluated using artifact power, mean signal-to-noise ratio and line profile. In this paper, SENSE reconstruction is performed with receiver coil sensitivities estimated using both the methods. This paper presents a comparison between two methods of estimating receiver coil sensitivities: (1) eigenvalue approach, in which a series of eigenvalue decompositions at the center of the acquired k-space are performed (2) pre-scan method which uses a low-resolution image to estimate receiver coil sensitivities. SENSE needs accurate estimates of the receiver coil sensitivity profiles to reconstruct fully sampled images from the acquired undersampled data. ![]() SENSE reconstruction is one of the PMRI algorithms most widely used in commercial MRI scanners these days. Parallel magnetic resonance imaging (PMRl) has the potential to decrease the MRI scan time by acquiring fewer k-space lines while using numerous independent receiver coils for data acquisition. One major limitation of MRI is its long data acquisition time. ![]() Magnetic resonance imaging (MRI) is a non-ionizing and non-invasive imaging modality. ![]()
