Faster mr imaging: imaging with half the data
WebMagnetic resonance imaging (MRI) is known to be a slow imaging modality and undersampling in k-space has been used to increase the imaging speed. However, … WebFeb 1, 1999 · 1. Introduction. The recent introduction of a new generation magnetic resonance (MR) system with an enhanced gradient system has dramatically changed body MR imaging. Faster and stronger gradients shorten the time required to refocus an echo as short as the order of 1 ms, thus decreasing the repetition time (TR) of the sequence.
