Скачать или смотреть Rad229 (2020) Lecture-01D: The Bloch Equations and Image Contrast

"Rad229: MRI Signals and Sequences" is a course offered in the Department of Radiology at Stanford University (2020).

Lecture01: The Bloch Equations and Image Contrast, is broken down into for mini-lectures. 

Lecture-01D reviews The Bloch Equations and Image Contrast. The learning objectives include: 

• Describe the addition of relaxation to the equation of motion to form the Bloch equations.
• Differentiate between the Bloch equations in the lab and rotating frame.
• Remember a few specific T1 and T2 values.
• Learn which magnetization components are governed by T1 and T2.
• Understand the importance of:
– Free precession with relaxation in the rotating frame.
– Forced precession without relaxation in the rotating frame.
• Discuss how RF pulses, T1, and T2 confer image contrast.
