Perfection!!! I'm having my MRI board on December, still struggling with the relationship of the different parameters, but I'm getting there 🙂that was very helpful. Thanks for sharing, you earned a subscription

Glad it was helpful!

Wait. How does smaller FOV decrease acquisition time? I thought this change alone leaves the matrix size unchanged and wouldn't that lead to same number of frequency and phase encoding steps?

What is Trade off in simple terms???
