Аннотация:It is shown that the replacement of X-ray tubes used in coronary angiography with laser-electron X-ray generators improves the quality of imaging and (or) reduces the radiation load
on the patient and the expenditure of the contrast agent. The main stages of the angiography procedure are implied to stay unchanged,and the advantages will be achieved at the expense of tuning the radiation spectrum to the absorption maximum of the contrast agent. The parameters of electron bunches and laser pulses interacting with them are determined that, on the one hand, provide the required flux of X-ray radiation and, on the other hand, obey the limitations imposed by the thermal and photoemission properties of the photocathode. These parameters can be implemented using the up-to-date achievements in laser and accelerator technology
