| Abstrakt: | Objective: The study the specific features of using diagnostic nanosecond X-ray pulse apparatuses versus X-ray diagnostic apparatuses using direct current X-ray tubes. Material and Methods: Dosimetric tests of ARDP-01 and Yasen-01 X-ray pulse apparatuses versus RUM2O and Siemens Axiom Iconos R200 apparatuses using direct current X-ray tubes were carried out. Results: The tests established that the patient radiation dose by a Yasen-01 apparatus is 2.5-3 times lower than that by a Siemens Axiom Iconos R200 apparatus. The radiation dose by an ARDP-01 apparatus was 10-20 times lower than that by a RUM20 apparatus when using film radiation detectors. Conclusion: The performed investigations demonstrate a manifold reduction in the lower X-ray radiation with the use of nanosecond X-ray pulse apparatuses as compared to the continuous radiation. Without changing the characteristics of a radiation detector, the dose can be further reduced by increasing the amplitude and decreasing the duration of the pulse of X-ray tube current, and raising the pulse ratio. |
