In vitro detection of apoptosis using superparamagnetic iron oxide nanoparticles and molecular magnetic resonance imaging
(2010)
Superparamagnetic iron oxide (SPIO) nanoparticles have the potential to greatly expand current anatomical imaging techniques, specifically MRI. SPIO nanoparticles targeted to phosphatidylserine (PS) have the potential to ...
Positron/electron annihilation via the two-photon pathway
(2012-11-10)
When a positron/electron pair annihilate via the two-photon pathway, the emitted photons are momentum correlated. This correlation ensures that they move along a straight line path in opposite directions. An experiment ...
Measurement of Rabi oscillation in a spin system
(2018)
This work proposes that during the application of an on-resonance MR-
pulse there exists a Rabi oscillating fi eld which can be directly measured
from a nuclear spin system. These oscillations have been previously ...
Amorphous selenium (a-Se) avalanche photodetector for applications in positron emission tomography (PET)
(2011)
Although avalanche amorphous selenium (a-Se) is a very promising photoconductor for a variety of imaging applications, it is currently restricted to applications with electron beam readout. This is performed with a vacuum ...
Theory and Production of Hyperpolarized Xenon Gas
(2015-12-03)
Conventional magnetic resonance imaging (MRI) modality is based on the magnetization
that is formed by the influence of a strong polarizing magnetic field on the spin of protons,
typically those of water molecules within ...
Ordered supramolecular oligothiophene structures on passivated silicon surfaces
(2014)
The adsorption of brominated tetrathienoanthracene molecules (TBTTA) onto the Si(111) 3-Ag surface has been studied. The molecules were absorbed at room temperature and annealed up to 400C. One monolayer of Ag was used to ...
Characterization of CdZnTe semiconductor for applications in advanced computed tomography
(2017)
Cadmium zinc telluride (CdZnTe) is currently the only single crystalline
semiconductor used in direct conversion gamma-cameras since CdZnTe can operate at
room temperature, unlike other materials (e.g., germanium) that ...
