Introduction: Phantom studies facilitate the implementation of radiation dose surveillance as a function of radiographic technical parameters for minimizing patient radiation dose. The evidence of such investigations can then be used to evaluate technical parameters used in the radiographic procedures to reduce radiation dose without compromising the image quality. Material and Methods: This ex...

An increase in the number of diagnostic procedures using ionizing radiation (computed tomography, interventional procedures, and use nuclear medicine) results an exposure and, consequently, collective individual doses to patients.
 Diagnostic studies from international professional community are extensively focusing on issues such as management dose optimization. Worldwide practice can res...

objective(s) as there are conflicting findings regarding the clearance-dose and patient characteristics relationships for valproic acid (vpa), this study was conducted to investigate the relationship between patient demographic characteristics, vpa dosage and the drug clearance in adult iranian patients. materials and methods patients (n= 47) were either on monotherapy with vpa or were under co...

Introduction: The CT Provide high quality images, especially in low-contrast soft tissue, are another advantage. Along with all the benefits that the CT scans which have, the patient dose of this modality is much greater than other methods. As a result, medical imaging community must ensure that the benefits of radiological examination for each patient are higher than related r...

background: with the introduction of computed tomography in diagnostic radiology a new and fundamentally different imaging modality has become available. meanwhile, it is clear that the absorbed doses by the patients during ct were relatively high in comparison with those of other diagnostic radiology techniques. the aim of this survey was to determine the average absorbed dose in yazd province...

background:  the aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. materials and methods: the dose rate from a sample of 192 patients administrated by three different radioactivity of 131i (3.7, 5.55 and 7.4 gbq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three differ...

Introduction: In radiation therapy, accurate dose determination and precise dose delivery to the tumor are directly associated with better treatment outcomes in terms of higher tumor control and lower post radiation therapy complications. The current study aims the development and clinical application of the Patient Specific Quality Assurance (PSQA) procedures for nasopharyngea...
