Opis:: Radiation is energy, and it is widely used in a variety of fields, especially in industry and medical science. In hospital, ionizing radiation like X-ray is an extensive exam that has been used to help physicians to have a view into the body, without having to make a medical application. Computed tomography scan uses ionizing radiation, and it is a nearly perfect diagnostic unit that allows the physician to see the picture of the human body. Computed tomography scan technology has progressed over the years, and it is an increasingly powerful and effective unit in the diagnostic radiology. Exposure to ionizing radiation is known to increase the risk of cancer. The aim of this study was to assess the radiation exposure received during computed tomography in a sample representative of the current state of practice in adult patients.

Opis:: Medical imaging is a technique that is mostly known as visual representations of the parts of body for clinical scans and analysis. In imaging process for medical purpose there take part radiologists, radiographers/radiology technicians, medical physicists, sonographers, nurses, and engineers. As an apart issue from the medical imaging devices, we can treat X-rays using devices such as radiography, computed tomography, fluoroscopy, dental cone-beam computed tomography, and mammography. All these devices are to perform X-ray using during medical imaging process. An X-ray beam is generated in a vacuum tube that is principally composed of an anode and a cathode material to produce X-ray beams, whose name is X-ray tube. The anode represents the component in which the X-ray beam produced that made from a piece of metal. For decades, tungsten (W) has been used as an anode material of various X-ray tubes. Tungsten has high atomic number and high melting point of 3370°C with low rate of volatilization. In this study, we performed Monte Carlo simulation for flux calculations of W target by using MCNP-X general purpose code and considered result as a data set for artificial neural network. It can be concluded that the results agreed well between Monte Carlo simulation and artificial neural network prediction.
