Editor’s Comment to Paper ST31

(February 8, 2008)  Although European News Forum publishes mainly papers originating from Europe, we gladly accept papers from overseas if these are especially timely and important.  In the Editor’s opinion this is the case of the paper ST31 by Zotev et al.

Readers of that paper might wonder why in discussing the speed of MRI data acquisition the authors did not mention the seemingly obvious possibility of further increasing the number of SQUID channels?  While it is so in principle, this possibility is subject to some limitations and deserves a detailed discussion.  Interested readers can find pertinent arguments in another, earlier paper by the same authors (“Parallel MRI at Ultra-low Fields” by V.S. Zotev, P.L. Volegov, A.N. Matlashov, M.A. Espy, J.C. Mosher and R.H. Kraus Jr), which is accessible at: http://arxiv.org/abs/physics/0701188.
