Background  It is remain a main concern that pediatric chest radiographies contribute to the significant radiation exposure to the thyroid gland as a more susceptible organ to radiation induced cancer. The aim of this study was to evaluate the entrance surface dose (ESD) of pediatric chest radiography compared to the diagnostic reference levels (DRL) and evaluation the efficacy of the lead (Pb)...

Background: During interventional cardiology processes, patients especially women and children receive high radiation doses due to their sensitivity.Objective: In this study, we evaluated a pediatric patient dose separately in those undergone intervention cardiac procedure. Material and Methods: In this cross sectional study, a public hospital with 252 patients, Entrance Skin Dose (...

background: application of dose-area product (dap) quantity has been increased in the clinical practice. dap is relatively easy to measure. dap has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. material and methods: in this study, measurements of dap were carried out in a sample of 421 adult patients who underwent conventiona...

IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...

In general, dose evaluation for mammography uses average glandular dose (AGD). In mammography, entrance surface dose (ESD) is high, which is well known, but actual clinical data of ESD are not reported so much. This study investigated AGD and ESD for patients whose doses were estimated from 200 mammography examinations using European Organization for Quality-Assured Breast Screening and Diagnos...

Background: Application of Dose-area product (DAP) quantity has been increased in the clinical practice. DAP is relatively easy to measure. DAP has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. Material and Methods: In this study, measurements of DAP were carried out in a sample of 421 adult patients who underwent convention...

Background: In diagnostic radiography, selection of kVp and mAs to produce acceptable image quality with a minimum dose has been challenge even for experience radiographers. The aim this study was determine optimal exposure factors lumbar spine AP examinations in computed radiograph using dose-image analysis. Materials Methods: A female anthropomorphic phantom used analysis the (mAs kVp) AP. In...

Background: One of the means of assessing dose to pa ents from Computed tomography (CT) procedure is through the determina on of the skin entrance dose (ESD) with the apprecia on of the concern that ocular exposure effects from CT scan includes possible induc on of cancer and cataract. Due to the rela vely more recent introduc on of CT scans, li le work has been done in this area in the country...

Background: Hysterosalpingography (HSG) is an indispensable tool for diagnosing infertility in females. The procedure exposes female reproductive organs to ionizing radiation as the genitals are irradiated during the process. Investigating patient absorbed dose during the procedures is essential for effective radiological protection of the patient. Objective: This study aims to investigat...
