Density scaling artifacts in dosimetry calculations
نویسنده
چکیده
Quality assurance dosimetry often requires the comparison of measured doses with those calculated by a treatment-planning system for phantoms of density other than 1.000 g/cm3. The presence of an artifact in the Pinnacle3 treatment-planning system can lead to systematic errors in such cases. These errors are also present, although reduced in magnitude, in heterogeneous media.

The power law scaling, geometric and kinematic characteristic of faults in the Northern part of the Kerman Coal Province (KCP), Iran
According to numerous studies, there are basic and initial scaling relationship for the geometric and kinematic characteristics of faults. The study area is located in the northern part of the Kerman coal province. The statistical calculations are consisting of: measure the surface density of faults per unite area and division of the area, determining the direction of the dominant faulting and...
متن کاملScaling relations in dynamical evolution of star clusters
We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...
متن کاملInvestigating the Feasibility of 3D Dosimetry in the RPC IMRT H&N Phantom.
An urgent requirement for 3D dosimetry has been recognized because of high failure rate (~25%) in RPC credentialing, which relies on point and 2D dose measurements. Comprehensive 3D dosimetry is likely to resolve more errors and improve IMRT quality assurance. This work presents an investigation of the feasibility of PRESAGE/optical-CT 3D dosimetry in the Radiologic Physics Center (RPC) IMRT H&...
متن کاملEvaluation of New Commercially Available Metal Artifact Reduction (MAR) Algorithm on Both Image Quality and Relative Dosimetry for Patients with Hip Prosthesis or Dental Fillings
Streaking artifacts on computed tomography (CT) images are caused by high density materials such as hip prosthesis, surgical clips and dental fillings. The artifacts can lead to compromised clinical outcome due to the inability to differentiate tumor volume and the uncertainties in dose calculation. The goals of our study are to evaluate how GE’s smart metal artifact reduction (MAR) algorithm i...
متن کاملDevelopment of Iranian Adult Female Reference Phantom for Internal Dosimetry Calculations
Estimation of organ doses in diagnostic and therapeutic nuclear medicine procedures is an area of particular concern for radiation protection, in all over the world. The stylized computational phantoms have contributed significantly to radiation dosimetry in nuclear medicine; however, their simplified treatment of human anatomy is being criticized. Due to the fact that the ICRP adult reference ...
