Phase Encoding - Video Lesson

Hey, everybody. Welcome to today's lesson on spatial encoding. This lesson focuses on phase encoding, including how it works and when it occurs during a pulse sequence. Phase encoding is one of the ways we are able to localize the MRI signal to specific locations in the body, so this concept is important to understand. Remember, spatial encoding in MRI is how we map the location of signals within the body to create a detailed image. Spatial encoding is performed by the gradient coils in the MRI scanner, which superimpose external magnetic fields on b sub zero, creating what is called a gradient magnetic field. Spatial encoding involves slice selection, frequency encoding, and phase encoding. Let's take a closer look at the process of phase encoding. Phase encoding is a method used to encode spatial information of a slice
