Implementación de un protocolo de control de calidad del equipo de rayos X TITAN-2000M para el Hospital General Provincial Docente Riobamba.

Abstract

The objective of this degree work was to design and implement a quality control protocol to the Xray equipment in the area of Imaging from Hospital General Provincial Docente Riobamba. Therefore, the physical principle of the equipment's operation was described, as well as its mechanical and electrical composition detailing the functional capacity, production and use restrictions. The characterization of the protocol was obtained based on the deductive method with which the tests were carried out. A 10% tolerance range imposed by the regulatory body controlled each test performed on the equipment. The tests implemented in the radiographic equipment provide technical information that helps to fulfill with the quality standards set by the Undersecretary of Control and Nuclear Applications. This protocol presents information on the electrical and mechanical functioning, with this the Occupationally Exposed Personnel (OEP) evaluates the level of efficiency of the equipment, at the same time the existing radiation in the image area is controlled, hence this dosimetry analysis was carried out to evaluate the existing level of radiation protection. To obtain a better precision approximately 5% in the kilovoltage measurement a milliamperage between 10 and 50 mA was used. The adjustment of the Automatic Exposure Control provided images about nonuniformity of the radiation field. The operating voltage presents an error of approximately 8.4%. Through a weighting of the dose rate it was found that the OEP absorbs an annual dose of 8.71 milliSievers. The image area must have a radiological safety inspector to prevent accidents, keep the protocol updated and maintain the safety of the OEP.
