MRI Phase and Frequency Matrix Explained
Рет қаралды 4,249
Күн бұрынMagnetic gradients are essential to creating an image in the MRI environment. This video helps explain how the body reacts to the use of gradient fields. All three gradients are used to separate the body in slices, and create a matrix of voxels containing unique phase and frequencies that are plotted into a usable image.

Very clear explanation.

Still doesn’t explain adequately what phase and frequency actually are.

This is specifically explaining the matrix, not the phase and frequency. It is assuming the viewer has some basic knowledge of MRI. This is part of a complete series that is visible to my students in an official program.

This is the key-point: 6:37. Besides frequency and phase there is an amplitude too. In the middle of k-space it is brightest.

@@jacobvandijk6525 Yes, the center of K-space is contrast while the outer sections is resolution. I use C for center and contrast, so the outer limits is resolution.
