BACKGROUND Intramedullary nailing under fluoroscopic guidance is a common operation. We studied the intraoperative radiation dose received by both the patient and the personnel. PATIENTS AND METHODS 25 intramedullary nailing procedures of the tibia were studied. All patients suffered from tibial fractures and were treated using the Grosse-Kempf intramedullary nail, with free-hand technique fo...

PURPOSE To assess radiation dose in common pediatric diagnostic fluoroscopy procedures and determine the efficacy of dose tracking and dose reduction training to reduce radiation use. METHODS Fluoroscopy time and radiation dose area product (DAP) were recorded for upper GIs (UGI), voiding cystourethrograms (VCUGs), and barium enemas (BEs) during a six-month period. The results were presented ...

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 (...

The goal of this study was to establish local diagnostic reference levels (LDRLs) for conventional radiography examinations in Sistan-Baluchestan province of Iran, using dose area product (DAP) measurements followed by a comparison with international dose levels. DAP factor evaluation was carried out at eight radiography rooms in six public and one private health-care centers. The study employe...

I ncreasing diagnostic and therapeutic applications of X-ray in medicine will potentially enhance the radiation dose received by the radiologists; this is of more importance when they perform especial procedures. Although the tube collimator will prevent the exposure of radiologists from primary radiation beam, the scattered radiation from the patient’s body will constitute a potential source o...

To assess patient radiation during catheter ablation procedures and operator differences. From 84 patients (51 males, age 63 ± 10 years) undergoing complex catheter ablation by three experienced operators we collected: body mass index (BMI), procedure type and time, fluoroscopy time, dose area product (DAP), air kerma and X-ray system setting (cine, collimation and angiographic imaging angle). ...

Research conducted to-date, makes use of the IBA-Lynx scintillating screen and radiochromic film to analyze proton field uniformity for dose-area product (DAP) determination. In this paper, machine log file based reconstruction is proposed calculate simplify measurement. order uniformity, dose distribution reconstructed on with matRad (an open source software analytical calculation in MATLAB). ...

In this study, dose-area product (DAP) measurements in panoramic dental radiology have been performed in Germany. The results obtained in this study were proposed as diagnostic reference levels (DRLs). A representative number of dental panoramic units, both with digital and conventional image receptors, have been chosen. Common statistical parameters such as mean, standard deviation and 3rd qua...

As dynamic flat-panel detectors (FD) are introduced in interventional cardiology (IC), the relation between patient dose and image quality (IQ) needs to be reconsidered for this type of image receptor. On one hand this study investigates IQ of a FD system by means of a threshold contrast-detail analysis and compares it to an image intensifier (II) system on a similar X-ray setup. On the other h...
