An on-site customer service engineer (cse) visited the customer site and determined that the device functioned as intended and the issue of high dose was due to user error.Discussion with the user revealed that they decided to perform the exposure with the panel in free mode, where the panel is placed on the tabletop and not in the table bucky.The pediatric patient was then positioned at the foot of the bed to perform the exposure.When the free selector was pressed, the generator console displayed error 0916; error 916 is a warning that a photo timed exposure can't be accomplished with the panel on the tabletop.To continue the procedure, the "m" button on the generator console was pressed by the user.After the m button was pressed, the generator console was left in table bucky state, with photo timing for exposure mode still active.When the user positioned the tube above the foot of the bed, there was approximately 30-36 inches of distance from the exposure point to the photo timing cell; when exposing in this condition there was enough scatter dose to satisfy the photo timer circuit to allow the exposure to continue, but not enough dose to terminate the exposure in the appropriate time for this study.There was no malfunction with the devices involved in this event; the re-imaging and high dose was due to user incorrect technique.If any additional relevant information is provided, a supplemental report will be submitted.
