Evaluation of the Effect of Tumor Position on Standardized Uptake Value Using Time-of-Flight Reconstruction and Point Spread Function
Objective(s): The present study was conducted to examine whether the standardized uptake value (SUV) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (PET) images, obtained via two methods based on time-of-flight (TOF) reconstruction and point spread function (PSF). Methods: A cylinder phantom with the sphere (30mm diameter), located in...
متن کاملDesign, Construction and Calibration of a Laser Ionization Time-of-Flight Mass Spectrometer
A time-of-flight mass spectrometer (TOF-MS) developed in our laboratory at Isfahan University of Technology is described here. The TOF-MS instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. The TOF-MS has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...
متن کاملA Modulated X-ray Source Controller for the In-Flight Calibration of X-Ray Astronomy Payloads
We designed and built a controller for a modulated X-ray source (MXS) that can be used to calibrate X-ray detecting instruments. This source has three adjustable inputs: the voltage supplied to an ultraviolet light-emitting diode (UV LED), a high voltage supplied to an electron multiplier, and a high voltage to accelerate electrons towards an elemental target. The controller provides both a gra...
متن کاملTHE CHANDRAYAAN-2 LARGE AREA SOFT X-RAY SPECTROMETER (CLASS). V.Radhakrishna
Introduction: The CLASS experiment on Chandrayaan-2, the second Indian lunar mission, aims to map the abundance of the major rock forming elements on the lunar surface using the technique of X-ray fluorescence during solar flare events. CLASS is a continuation of the successful C1XS [1] XRF experiment on Chandrayaan-1. CLASS is designed to provide lunar mapping of elemental abundances with a no...
