Design of a Gaussian Filter for the J-PARC E-14 Collaboration

چکیده
This paper describes the design, simulation, and pulse fitting result for a Gaussian filter built for the J-PARC E-14 collaboration. The filter is a 10-pole shaper designed to produce a Gaussian-shaped output pulse in the time domain. The performance of the filter was studied for various levels of energy deposited, as well as different rates of asynchronous sampling. At a sampling rate of 125MHz, timing resolution is better than 0.5ns when the energy deposited is greater than 10MeV . For a pulse with an energy of 200MeV , the timing resolution is approximately 110ps.

Determination of the optimum filter for qualitative and quantitative 99mTc myocardial SPECT imaging
Background: Butterworth, Gaussian, Hamming, Hanning, and Parzen are commonly used SPECT filters during filtered back-projection (FBP) reconstruction, which greatly affect the quality and size accuracy of image. Materials and Methods: This study involved a cardiac phantom in which 1.10 cm thick cold defect was inserted into its myocardium wall and filled with 4.0 μCi/ml (0.148 MBq/ml) 99mTc conc...

Introduction & Objective: Fluoroquinolones are essential antimicrobial agents used to treat UTIs. Clinical experiences have shown a high rate of antibiotic resistance among uropathogens. These resistance are usually the consequence of mutations involving genes encoding gyrA and parC. The aim of this study was to determine antimicrobial resistance pattern and the presence of mutations in regions...

Background: In myocardial perfusion SPECT imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. Filters greatly affect quality of nuclear medicine images Materials and Methods: A phantom simulating heart left ventricle was built. About 1mCi of 99mTc was injected into the phantom. Images were taken from this phantom. Some fi...
