background: electronic portal imaging devices (epids) play an important role in radiation therapy portal imaging, geometric and dosimetric verifications. a successful utilization of epids for imaging and dosimetric purposes requires a reliable quality control process routine to be carried out regularly. in this study, two in-house phantoms were developed and analyzed for implementation in a qua...

abtract background: in nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  in this study the hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. the phantom is modified to acquire tomographic and planar i...

The $^{9}\mathrm{Be}(^{25}\phantom{{}^{B}e}\mathrm{F}(5/{2}^{+}),^{24}\phantom{{}^{B}e}\mathrm{O}$)X proton-removal reaction was studied at the NSCL using S800 spectrometer. experimental spectroscopic factor for ground-state to transition indicates a substantial depletion of proton ${d}_{5/2}$ strength compared shell-model expectations, similar findings an inverse-kinematics $(p,2p)$ measuremen...

Introduction: One of the most valuable goals of phantoms, replacing with human goals in the field of research and quality control of diagnostic X-ray systems. There are various algorithms and methods for obtaining Homogeneity and CT number linearity for CT scan device. One of the most famous of these methods, the method is to use a uniform and homogeneous environment to comput...

The authors derive a new density-dependent point-coupling covariant density functional (PCF-PK1) with exchange terms that are local and can be included in standard relativistic mean-field calculation. This saves considerable amount of computing time over Hartree-Fock calculations nonlocal potentials. PCF-PK1 is obtained by fitting nuclear matter finite nuclei, including the results $a\phantom{\...

Introduction: The determination of accurate dose distribution is an issue of fundamental importance in radiotherapy, especially with regard to the fact that the human body is a heterogeneous medium. Therefore, the present study aimed to analyze the density and isodose depth profiles of 6 MV beam in a SP34 slab-wooden dust (pine)-SP34 slab (SWS) heterogeneous phantom.  Materials and Methods: Th...

The time-dependent $CP$ asymmetries of $B^0\to \pi^+\pi^-$ and $B^0_\mathrm{s}\!\to K^+K^-$ decays are measured using a data sample $pp$ collisions corresponding to an integrated luminosity 1.9 fb$^{-1}$, collected with the LHCb detector at centre-of-mass energy 13 TeV. results \begin{eqnarray*} C_{\pi\pi} & = -0.311 \pm 0.045 0.015, \\ S_{\pi\pi} -0.706 0.042 0.013, C_{KK} \phantom{-}0.164 0.0...
