Figure 2: Reconstructed images and error maps in the noise reduction test using phantom images.
From: A New Joint-Blade SENSE Reconstruction for Accelerated PROPELLER MRI

MJB SENSE consistently resulted in substantially lower noise than SSB SENSE at all acceleration factors (R). The images shown were reconstructed from data with SNR = 20. The blade number was 16, ETL 10, and the number of coils 8. The error maps at R = 4, 5, and 6 are displayed at ×10, ×10, and ×5, respectively. All images were cropped to 200 × 200.
