Impurity Diagnostics Lifetime Spectroscopy
2008/10/30
This paper gives a review of some recent developments in the field of contactless silicon wafer characterization techniques based on lifetime spectroscopy and infrared imaging. In the first part of th...
A Ratiometric Fluorescence Imaging System for Surgical Guidance
CCD imaging system optical absorption and scattering PpIX
2011/4/21
A 3-chip CCD imaging system has been developed for quantitative in vivo fluorescence imaging. This incorporates a ratiometric algorithm to correct for the effects of tissue optical absorption and scat...
An adaptive optics imaging system is introduced in this paper. A high-resolution liquid crystal on silicon (LCOS) device was used as a phaseonly wavefront corrector instead of a conversional deformabl...
When a diffuse object is illuminated with laser light, a random interference effect known as a speckle pattern is produced. If there is movement in the object, the speckles fluctuate in intensity. The...
Novel statistical approach for segmentation of brain magnetic resonance imaging using an improved expectation maximization algorithm
expectation maximization maximum likelihood magnetic resonance imaging (MRI)
2011/4/28
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...
