E.  23). From what has been said so far, one might conclude that the matrix should be as large as possible in order to encompass a maximum of picture elements. This is true in terms of image resolution but the minimum pixel size is limited by the fact that, in general, SNR decreases with the size of the voxel. Another limiting factor is image acquisition or scan time, which increases in direct proportion to the matrix size. Scan time is the key to the economic efficiency of all MR systems and can be calculated by a simple equation.

Another limiting factor is image acquisition or scan time, which increases in direct proportion to the matrix size. Scan time is the key to the economic efficiency of all MR systems and can be calculated by a simple equation. Scan time = TR × number of phase-encoding steps × number of signal averages (NSA) [echo train length (ETL)]. 5 Factors Affecting the Signal-to-Noise Ratio 33 Fig. 21. Effect of the FOV on pixel size with the matrix size held constant Fig. 22. A smaller matrix size with the FOV held constant results in larger pixels and thus a poorer spatial resolution A “trick” can be used to achieve a high spatial resolution in a reasonable scan time.
