Evaluation of patient exposure with Flat Panel Detector (FPD) in X-ray TV system
The use of flat-panel detector (FPD) systems in TV equipment for gastrointestinal tract examination is increasing. The use of FPD systems is believed to reduce the exposure dose. When our institution changed its TV equipment from an image intensifier (GE;MS90Tj) system to an FPD (Shimadzu;SONIALVISION safire DAR-3500) system, we measured the doses produced and carried out a comparative examinat...
متن کاملPatient 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 ...
متن کاملPatient dose in routine X-ray examinations in Yazd state
Background: Medical x-rays are the largest man-made source of public exposure to ionizing radiation. It is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. Materials and Methods: The Entrance Skin Exposure (ESE) measurement was conducted for quality control of x-ray machines and survey of operator’s experimental techniques. The ESEs we...
متن کاملParameters affecting the X-ray dose absorbed by macromolecular crystals.
The lifetime of a macromolecular crystal in an X-ray beam is assumed to be limited by the absorbed dose. This dose, expressed in Gray (Gy = J kg(-1)), is a function of a number of parameters: the absorption coefficients of the constituent atoms of the crystal, the number of molecules per asymmetric unit, the beam energy, flux, size and profile, the crystal size, and the total irradiation time. ...
متن کاملEvaluation of X-ray absorbed dose in thyroid during CXR imaging of the chest by Monte Carlo simulation (DOSXYZnrc)
Abstract: Introduction: Chest radiography is one of the most common X-ray imaging procedures performed worldwide. During this process, in addition to the chest, other tissues, including the thyroid, are also exposed to radiation. Due to the fact that one of the most important risk factors for thyroid cancer is ionizing radiation, measuring the absorption of X- rays in the thyroid is of spec...
