CTV to PTV Margins Based On CBCT Method for Prostate Cancer of Patients Treated With VMAT Technique [PDF]

Iranian Journal of Medical Physics, 2023
Introduction: Patient repositioning in treatment radiotherapy is one of the main factors that increase error of target irradiation. However additional margin is necessary to consider the uncertainties created along and around X, Y and Z-axis.Material and

Adaptive ensemble PTV [PDF]

Measurement Science and Technology, 2020
Abstract Ensemble particle tracking velocimetry (EPTV) is a method to extract high-resolution statistical information on flow fields from particle image velocimetry (PIV) images. The process is based on tracking particles and extracting the velocity probability distribution functions of the image ensemble in averaging-regions deemed ...

Surface flow profiles for dry and wet granular materials by Particle Tracking Velocimetry; the effect of wall roughness [PDF]

, 2019
Two-dimensional Particle Tracking Velocimetry (PTV) is a promising technique to study the behaviour of granular flows. The aim is to experimentally determine the free surface width and position of the shear band from the velocity profile to validate ...

P- and T-violating $\pi N N$ form factor [PDF]

, 2006
The form factor of the parity and time-reversal violating (PTV) pion-nucleon interaction is calculated from one-loop vertex diagrams. The degrees of freedom included in the effective lagrangian are nucleons, pions, $\eta$, $\rho$ and $\omega$ mesons.
