Matrix Size
 
The number of data points collected in one, two or all three directions. Normally used for the 2D in plane sampling. The display matrix may be different from the acquisition matrix, although the latter determines the resolution. Measurement time may be saved by not acquiring raw data lines corresponding to high resolution. Not measured rows are filled with zeroes prior to the image calculation. A square image is the result of an interpolation in phase encoding direction. See also Zero Filling.

Image Guidance
The chosen matrix size effects scan time, resolution and SNR. Reduced measurement matrixes decrease the scan time and the resolution by increased SNR.

Maximum Intensity Projection
 
(MIP) MRA images can be processed by Maximum Intensity Projection to interactively create different projections. The MIP connects the high intensity dots of the blood vessels in three dimensions, providing an angiogram that can be viewed from any projection. Each point in the MIP represents the highest intensity experienced in that location on any partition within the imaging volume.
For complete interpretation the base slices should also be reviewed individually and with multiplanar reconstruction (MPR) software. The MIP can then be displayed in a CINE format or filmed as multiple images acquired from different projections. Although the maximum intensity projection (MIP) algorithm is sensitive to high signal from inflowing spins, it is also sensitive to high signal of any other etiology.

 - Coils -
 
A particular kind of gradient coil, commonly used to create magnetic field gradients along the direction of the main magnetic field. The maxwell coil consists of a pair of coils separated by 1.73 times their radius. Current flows in the opposite sense in the two coils, and produces a very linear gradient.

Measurement Field
 
The spherical volume in the center of the magnetic field where the field has a defined homogeneity. Measured objects must always be positioned in the measurement field.
