ABSTRACT

Purpose: Investigation of diagnostic and operational capabilities of pulsed nanosecond X-ray complex compared with commercial X-ray systems based on DC-tubes using digital flat panel detectors.

Material and methods: 3 X-ray systems are considered: pulsed X-ray source Jasen-01 with Carestream DRX-1 detector, Definium AMX 700 mobile apparatus with General Electric detector, Evolution HV complex with Canon CXDI-40EC panel detector. The analysis of these systems is based on images quality evaluation and effective dose measurement. DKS-AT 1123 detector and Unifors Xi dosimeter are used for devices radiation parameters control.

Results: Analysis of digital X-ray images shows good results of pulsed system. Snapshots taken by using this device have the same quality as one obtained with Definium AMX 700 system, and its insignificantly is worse than a typical one for Evolution HV. Using pulsed X-ray source with digital detector, we achieve up to 25 times dose decreasing compared with commercial systems with DC-tubes.

Conclusion: Application of pulsed X-ray sources with digital detectors allows to reduce the dose by 25 times comparing with DC-sources. This result is especially important for C-arm device exploitation. Since it operates in real-time mode, application of pulsed X-ray systems with the digital detector significantly decreases patients and medical staff dose and increases the duration of the procedures under X-ray control.

Key words: pulsed X-ray diagnostic system, reduction of radiation exposure, equivalent dose, X-ray, digital detector
