Miscellaneous Topics,n the magnetic field from one point in space to another. Also, each gradient produces the same basic effect on protons: the vector precession frequencies are changed. Therefore, the particular task each gradient performs is determined by essentially one thing: . in the pulse cycle the gradient is applied.作者: BULLY 時間: 2025-3-22 07:52
Overview,in fact, there will be times when we must cross the “border” from one division to the other when considering certain topics. This will become clearer as we proceed, so let us begin with the first area: how we create tissue contrast in MRI.作者: 避開 時間: 2025-3-22 08:43
Radiofrequency Pulse,ticle or a magnetizable substance would experience will vary in time from a maximum in one direction to a maximum in the opposite direction. It turns out that this variation in time can be mathematically described with a simple sine or cosine function.作者: 不發(fā)音 時間: 2025-3-22 15:50 作者: 石墨 時間: 2025-3-22 20:12

T2 and the Spin-Echo Pulse Cycle,In preceding chapters, we glibly referred to the T2 decay of the Bl vector after application of the RF pulse. Actually, we oversimplified the case in order not to obscure the understanding of the relationship of T1 and T2 to TR and TE. But now, it is time to delve more deeply into what T2 actually is.作者: 錫箔紙 時間: 2025-3-24 01:55 作者: 欺騙世家 時間: 2025-3-24 05:38
Frequency Gradient,So far, we have shown how we select an image plane, which represents only the first of the three coordinates that we must specify. To complete our image, we must understand how the other two orthogonal gradients specify the other two coordinates of each point in a given plane.作者: 異端邪說下 時間: 2025-3-24 08:03
The Fourier Transform,We will eventually show that a Fourier transform is a spectrum. Hence it is necessary to know what a spectrum is.作者: Jogging 時間: 2025-3-24 14:02 作者: 說笑 時間: 2025-3-24 18:53
