Abstract
Obtaining quality images in fluoroscopy depends, among other factors, on the skill of the technologist, the radiographic procedure and, especially, the performance of the equipment used. Regarding equipment performance, various quality control protocols have been developed that establish a set of tests to evaluate different parameters related to image quality and the dose received by the patient. The execution of these tests requires radiation detection equipment to evaluate electrical parameters and the quantity of radiation received by the patient as well as phantoms that allow for simulation of patients. These devices are quite expensive and are not available in the domestic market. Therefore, the performance of the equipment of several medical centers located in Tunja (Boyacá) and Bogotá, Capital District, was evaluated using prototypes manufactured domestically according to the recommendations of the American Association of Physicists in Medicine (AAPM) for skull phantoms in adults and based on anthropometric relationships. Execution of quality control protocols with the phantom prototypes indicated that all of the equipment performed in accordance with the tolerance limits and reference levels established in both protocols, with the exception of remote control equipment, which did not exhibit the desired spatial resolution tolerance. In general, among the evaluated equipment, the angiograph produced the best image quality, and the one that delivered the lowest dose to the patient was manufactured by Philips. Additionally, we established and documented for the first time a specific configuration for the development of quality control tests for angiography equipment.
