| Abstract | |
Quality control tests were elaborated and implementated in digital subtraction angiography equipments. These tests were elaborated based in national and international standards, and they were implementated in five equipments of three different institutions. These tests are utilized to evaluate the performance of these equipments and to determine the patient entrance and personnel air kerma rates. The tests were performed using test tools, patient phantoms e ionization chambers. The conventional tests and the tests of the digital subtraction systems indicated that the evaluated equipments presented a good performance. The tests implementated to determine the air kerma rates presented, in one case (fluoroscopy equipment), high patient entrance skin air kerma rate. This problem was notified, and the providences were promptly taken by the hospital administration. (AU) | |
