Abstract
A comparison of two methods of subwavelength imaging is undertaken. Pendry's superlens is compared with a computational image reconstruction technique. In both cases, limitations of materials impose limits on resolution. Both systems have similar limits, suggesting that resolution restrictions on Pendry's superlens apply generally to various forms of subwavelength imaging. Β© 2009 Wiley Periodicals, Inc.

To depict the three-dimensional distribution of 99mTc-pyrophosphate in the heart, emission computed tomography (ECT) was performed, following the conventional planar imaging, in 32 cases with suspected acute myocardial infarction (AMI). There were 23 cases with evidence of AMI, 7 with unstable angin
## Abstract The aim of the study was to investigate whether quantitative magnetic resonance (MR) fast spinβecho (FSE) imaging with moderate spatial resolution enables osteodensitometry in peripheral yellow bone marrow. Signal intensities in T1βweighted FSE images from yellow bone marrow indicate th
