ON THE COMPENSATING FILTER IN PRECUTANEOUS CHOIANGIOGRAPHY (II. Supplemental Tool for X-ray Examination)

Patient effective dose evaluation for chest X-ray examination in three digital radiography centers

Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

X-ray spectra calculation for different target-filter of mammograms using MCNP Code

 ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...

Impact of quality control on radiation doses received by patients undergoing abdomen X-ray examination in ten hospitals

  ABSTRACT   Background: The X-ray machines used for radiodiagnosis should meet certain quality assurance (QA) programmes . These are necessary to have good quality radiographs at reasonably low exposure to patients.   Materials and Methods: Dose reduction methods in abdomen X-ray examination were carried out in 10 hospitals in Tehran. This paper presents the work, which was implemented on 200 ...
