Development and implementation of a Monte Carlo frame work for evaluation of patient specific out- of - field organ equivalent dose
Background: The aim of this study was to develop and implement a Monte Carlo framework for evaluation of patient specific out-of-field organ equivalent dose (OED). Materials and Methods: Dose calculations were performed using a Monte Carlo-based model of Oncor linac and tomographic phantoms. Monte Carlo simulations were performed using EGSnrc user codes. Dose measurements were performed using r...

15 صفحه اولSocial Work in Mental Hospitals and Out-Patient Clinics
The Child Guidance Council has always been interested in demonstrating the value of psychiatric social work for adult patients. As far back as 1927, a worker was loaned to the psychiatric department of a general hospital, but it was not till 1930 that a beginning was made in introducing such workers into hospitals dealing with acute mental patients. In 1929 permission had been obtained for stud...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
CHIRON efficiency tests
We have injected a HeNe laser at 543 nm into the science fiber. A set of lenses and a diaphragm (in collimated space) were used after the laser to inject the beam with the correct focal ratio. The diameter of the diaphragm was set to 4 mm, while the focal length of the focusing lens was 19 mm, which gives an input focal ratio (IFR) of F/4.75. After aligning the fiber in x, y and z directions, w...
