Optically detected magnetic resonance investigations of diluted magnetic semiconductors
magnetic resonance diluted magnetic semiconductors spin flip interactions spin dynamics
2011/4/28
Mechanisms responsible for optical detection of Mn2+ magnetic resonance in II-Mn-VI compounds are discussed. We describe several of these mechanisms. The most efficient one which is due to very effici...
Novel statistical approach for segmentation of brain magnetic resonance imaging using an improved expectation maximization algorithm
expectation maximization maximum likelihood magnetic resonance imaging (MRI)

In this paper, an improved expectation maximization (EM) algorithm called statistical histogram based expectation maximization (SHEM) algorithm is presented. The algorithm is put forward to overcome t...
Hyperpolarized 3He gas production by metastability exchange optical pumping for magnetic resonance imaging
hyperpolarized 3He lung imaging low field MRI
2011/4/26
A portable 3He gas polarizer based on metastability exchange optical pumping is described. It produces 75 ml of highly polarized 3He gas at the pressure of 100 mbar, by implementing a non-magnetic per...
