Laser-based medical techniques for evaluating blood flow (BF), such as laser Doppler flowmetry, speckle contrast imaging, etc., are known, but expensive and have some disadvantages. Recently, we proposed a new technique—incoherent optical fluctuation flowmetry (IOFF), which is realized using LED-based probe. This work aims to theoretically study the dependence of BF registered by IOFF on source...

Monte Carlo simulations are nowadays an essential tool in emission tomography (Single-Photon Emission Computed Tomography— SPECT and Positron Emission Tomography—PET), for assisting system design and optimizing imaging and processing protocols. Several Monte Carlo simulation software are currently available for modeling SPECT and PET configurations. This paper presents an overview of current tr...

Detailed Monte Carlo (MC) modeling of the Leksell Gamma Knife (GK) Perfexion (PFX) collimator system is the only accurate ab initio approach appearing in the literature. As a different approach, in this work, we present a MC model based on film measurement. By adjusting the model parameters and fine-tuning the derived fluence map for each individual source to match the manufacturer's ring outpu...

The CGMF code implements the Hauser-Feshbach statistical nuclear reaction model to follow de-excitation of fission fragments by successive emissions prompt neutrons and $\gamma$ rays. Monte Carlo technique is used facilitate analysis complex distributions correlations among observables. Starting from initial configurations for in mass, charge, kinetic energy, excitation spin, parity, $Y(A,Z,KE,...

Introduction: The heavyweight concretes have been widely used for constructing medical or industrial radiation facilities with photon sources. Materials and Methods: In this study, heavy concretes containing galena (PbS) and several borated minerals are proposed as suitable materials against photons. The shielding properties of 21 galena concretes containing seven borated minerals with three m...
