Philips investigated this complaint and came to the following conclusion: the high x-ray dose of 31 gy for the patient at (b)(6)2014 can be explained by the length and intensity of the examination.The total duration of this examination was about 6 hours (from 9:49 till 15:56).The total fluoro time was 275 minutes (4 hours and 35 minutes).During the whole examination biplane fluoro was used, and only a few cine runs.The philips field service engineer and the investigator who checked the log files were unable to identify a malfunction of our allura xper fd10/10 system.No malfunction of the philips system has been identified based on the available information.The performed procedure had a very long duration.In addition, the customer barely moved the system, which means that almost all the time the same body part of the patient was exposed.Taken together, the long duration of the procedure and the long total fluoroscopy time are causing the high ak of 31 gy for this examination and contributed to the development of a radiation burn.
