Time-Shared X(v1)-Half-Filter for Improved Sensitivity in Subspectral Editing
نویسندگان
چکیده
a Experiments with X-half-filter elements allow the separation of the resonances from protons bound and unbound to a spin X into different subspectra. This Communication presents a modified half-filter element where the filter delay is simultaneously used for chemical shift labeling and scalar coupling evolution in a semiconstant time experiment. The filter element is demonstrated with a H NOESY spectrum of a 28.5-kDa 2:1 complex between the niformly C-labeled N-terminal domain of Escherichia coli arinine repressor and operator DNA. © 2000 Academic Press

Background and purpose: Imaging which is used in nuclear medicine is done using emit gamma rays whereas therapy in nuclear medicine is performed by applying radionuclide’s which emit beta radiation. Using Bremsstrahlung is a new field which is recently introduced in imaging. In the Bremsstrahlung imaging, collimator design should not be based on energy peak and whole energy spectrum should be c...
متن کاملImpact of Photon Spectra on the Sensitivity of Polymer Gel Dosimetry by X-Ray Computed Tomography
Introduction: The purpose of the current study was to investigate the effect of X-ray spectra on the sensitivity of a polymer gel dosimeter imaged with a conventional computed tomography (CT) scanner. Material and Methods: The whole process of CT imaging of an irradiated polymer gel was simulated by MCNPX Monte Carlo (MC) code. The imaging of polyacrylamide gel was accomplished by means of a co...

Background: In intensity modulated radiation therapy, cone beam computed tomography (CT) has been used to evaluate patients prior to treatment. This study conducted a comparative evaluation of the image reconstruction ability of the clinically used half-fan bowtie filter and the full-fan bowtie filter. Materals and Methods: A CT simulation marker was inserted inside a human phantom, and the pel...

Background: Accurate computation of the radiation dose to the breast is essential to mammography. Various the thicknesses of breast, the composition of the breast tissue and other variables affect the optimal breast dose. Furthermore, the glandular fraction, which refers to the composition of the breasts, as partitioned between radiation-sensitive glandular tissue and the adipose tissue, also h...
