What is the phase matrix in MRI?

The matrix size is the number of frequency encoding steps, in one direction; and the number of phase encoding steps, in the other direction of the image plane. Assuming everything else is constant, increasing the number of frequency encodings or the number of phase steps results in improved resolution.

What determines the matrix in MRI?

This is determined by the phase and frequency encoding gradient. The frequency encoding gradient will control the size of our field of view and the phase encoding gradient will determine our image matrix.

What is matrix in imaging?

Matrix. A matrix is a square arrangement of numbers in columns and rows, and in digital imaging, the numbers correspond to discrete pixel values. Each box within the matrix also corresponds to a specific location in the image and corresponds to a specific area of the patient's tissue.

What is phase encoding and frequency encoding in MRI?

The phase encoding gradient (GPE) intervenes for a limited time period. While it is applied, it modifies the spin resonance frequencies, inducing dephasing, which persists after the gradient is interrupted. This results in all the protons precessing in the same frequency but in different phases.
