After the introduction of a prototype device for digital subtraction angiography in 1980., this radiological method began to be increasingly applied in clinical practice. Today, DSA is used as the gold standard for displaying blood vessels using an iodine contrast agent. The device for DSA is complex, and the main parts are an x-ray tube, a generator and detectors. Precisely because of the complexity of the device, it is necessary to regularly perform quality control in order for the device to be standardized, which means that the quality of the examination needs to be the same in all parts of the world. Quality control includes observation, evaluation and maintenance of search procedures at optimal levels. Quality control is performed by a radiological technologist, medical physicist, service technicians and inspections. Also, quality control is performed monthly and annually. Physicists use various phantoms quality control. Some of the controlled parameters on DSA devices are half-absorption thickness, radiation field size, high and low contrast resolution and various dose parameters.
