Introductory NMR & MRI: Video 06: Spin echoes, CPMG and T2 relaxation
Date: Jan 15, 2013
Paul Callaghan gives an introduction to NMR and MRI. In this 6th video of the series, Paul delves into the spin echo, illustrating what is happening to the spins in this process and how the echo is created. The discussion then extends to the full CPMG pulse sequence and how this leads us to the important irreversible relaxation term T2.
Introductory NMR & MRI: Video 07: Measuring T1 and T2 Relaxation
Date: Jan 15, 2013
Paul Callaghan gives an introduction to NMR and MRI. In this 7th video of the series, Paul looks in depth at T1 (‘spin-lattice’) relaxation, and T2 (‘spin-spin’) relaxation, and measure these for a sample of water.
Introductory NMR & MRI: Video 08: Magnetic Resonance Imaging
Date: Jan 15, 2013
Paul Callaghan gives an introduction to NMR and MRI. In this 8th video of the series, Paul now moves to Magnetic Resonance Imaging (MRI) and carries out a very simple but informative 1D imaging experiment using a phantom sample containing two tubes of water.
Introductory NMR & MRI: Video 09-1: Introduction to k-space
Date: Jan 15, 2013
Paul Callaghan gives an introduction to NMR and MRI. In this 9th video (part 1) of the series, Paul introduces the viewer to the critical concept of k-space, clearly showing how spatial information in the physical sample is encoded using a field gradient and how this is represented in k-space. This video is given in a short lecture format.
Introductory NMR & MRI: Video 09 part 2: k-space in multiple dimensions
Date: Jan 15, 2013
Paul Callaghan gives an introduction to NMR and MRI. In this 9th video (part 2) of the series, Paul extends the discussion of k-space to two and three dimensions. The key concepts of traversing a two dimensional k-space are clearly presented, showing the pulse sequences used to move about in k-space and acquire the proper signal. The concepts presented in this video are the fundamental building blocks of any magnetic resonance imaging, including full body medical MRI. This video is given in a short lecture...
Introductory NMR & MRI: Video 10: 2D MRI
Date: Jan 15, 2013
Paul Callaghan gives an introduction to NMR and MRI. In this 10th video (part 2) of the series, Paul uses the Terranova-MRI to perform two dimensional imaging experiments to practically demonstrate the k-space and imaging concepts presented in video 9 part 2. Both Cartesian imaging, and Filtered Back Projection, methods are shown.
