Distortions in electrocardiogram (ECG) signals affect the image quality and increase scan time of Cardiac Magnetic Resonance Imaging (CMRI) exams. This study proposes an alternative method of acquiring CMRI cine images in mouse heart using a self-gated Ultra-short Echo Time (UTE) protocol. In our method, a bandpass filter and a lowpass filter are adopted to extract the self-gated signals from the...
This paper proposes a compressive sensing (CS) method for radial Magnetic Resonance Imaging (MRI) using nonuniform fast fourier transform (NUFFT). With the Ultra-short Echo Time (UTE) technology, radial MRI can reduce scan time, reduce artifacts, and achieve high imaging quality. We show that NUFFT-CS reconstruction from under-sampled radial k-space measurements achieves better image quality than...
