WebαE = arccos ( e−TR/T1 ) Note that this equation predicts that the optimal flip angle will be 90° only when TR>>T1. As an example, let us calculate the optimal flip angle for such a sequence in the brain (where the average T1 = 800 msec). When TR = 3000, the Ernst angle is computed to be 89°. In this situation, a conventional 90° pulse is ... WebThe Ernst angle concept has already been introduced in a previous Q&A to which the reader is referred for more details. It should be noted that although the Ernst angle gives the highest signal for a given tissue for a certain TR/T1 combination, it does not necessarily maximize image contrast between two different tissues.
WebPurpose: In order to fully benefit from the improved signal-to-noise and contrast-to-noise ratios at 9.4T, the challenges of B1+ inhomogeneity and the long acquisition time of high-resolution 2D gradient-recalled echo (GRE) imaging were addressed. Theory and methods: Flip angle homogenized excitations were achieved by parallel transmission (pTx) of 3 … WebFigure 5 shows MR magnitude images for three echo signals (RF 1, RF 2, and RF 3) obtained from the composite RF pulses in the phantom.Especially, the first row …
