scan matrices and steps
Hello,
I've just joined this forum because I'm a Japanese-English translator and often translate MRI related material, but my knowledge is a bit patchy. I have a rather basic question. Part of a product specification goes (translated):
Scan Matrix: 64 – 1024 x 64 – 1024; 4 steps per

I assume this is 4 steps per scan, but wanted to check just in case. Also could anyone explain what is meant by steps in this context?

Thanks very much

 Ah, just to answer my own question, I'm guessing this means the scan resolution goes up in increments of 4.

 It means that the matrix is variable, so you can choose to have 256, 260, 264 etc matrixes. This is than again part of how advanced the fourier transformation algorithm is.

Cheers

BTW Matrixes are just a number, and actually say nothing at all regarding resolution...yess FOV devided by matrix gives you a pixel size which is actually the interesting part.
