Elaboración de un manual de procedimientos para el tomógrafo Toshiba Activion en el Departamento de imagenología del Hospital Provincial General Docente Riobamba.

Abstract

This investigation aimed at elaborating a manual of procedures performed in the areas of the skull, thorax and abdomen for the Tomograph TOSHIBA ACTIVION in the Provincial General Scholastic Hospital Riobamba. It was started by preparing a manual of operating procedures and the implementation of quality control and radiological protection test within the tomography room. This manual was prepared based on different references from national and international institution and organization, moreover, the resources and needs of the hospital were taken into account, ensuring the obtainment of images with good quality, and trying to work with the lowest possible dose. Due to the lack of budget of the hospital, only mechanical and electrical equipment test have been carried out, this is the reason why it was proposed to conduct the quality control and radiological protection measurements to control the operation of the equipment. For the implementation of quality control, it was detailed the distinct test such as exposure control, quality of image and maintenance, which were measure using materials such as dosimeters, a kilovoltmeter, temperature detector, etc. But not all the test were carried out due to the lack of access codes to the tomograph system and the lack of specific equipment. In the end, the results in the test of exposure control, maintenance, and radiological protection are below the levels established by the Regulatory Authority (SCAN), but the values of leakage radiation were 0,0089 mSv/h at the access doors of patients, being higher values than those that should be measure. It is recommended to have in the department a specialist in ionizing radiation control, who applies the different procedures and test of the equipment and to guarantee the safety of the personnel.
