background: in diagnostic radiology lead apron, are usually used to protect patients and radiology staff against ionizing radiation. lead apron is a desirable shield due to high absorption and effective attenuation of x-ray photons in the diagnostic radiology range. objective: although lead aprons have good radiation protection properties, in recent years, researchers have been looking for alte...

Introduction: LiF dosimeter has the most application in medicine. This study aimed to evaluate some dosimetric properties of a novel LiF: Mg, Ti. Materials and Methods: An ELEKTA Precise linear accelerator was used to calibrate dosimeters at 6 MV. In this survey, responses of dosimeters were evaluated up to 1000 cGy. Background effect was investigated in two different dosimeter states includin...

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...

A dosimetry system using commercially available pin silicon photodiodes as the sensor is evaluated for in-phantom dose measurements in x-ray CT and other diagnostic radiology. System sensitivity measured as a function of the effective energy of x rays was between 0.37 and 0.49 V/mGy at an effective energy range between 23.5 and 72 keV. The minimum detectable organ dose with 25% uncertainty was ...

introduction: good radiographs are required for endodontic therapy and because some patient’s are intolerant to intraoral films and/or sensors, this can cause complications in endodontic treatment. extraoral film placement can be used to obtain clinically diagnostic and working radiographs. materials and methods: the no. 2 receptor was placed against the model ’ s cheek and centered in the mola...
