Int ref: (b)(4).This digitaldiagnost c 90 high performance system is a direct digital radiography system with flat detector technology (fixed or mobile detectors) based on modular components to allow for customization for all radiographic applications and workload requirements.This radiography system is equipped with ceiling suspended column csm3 (carrying the x-ray tube, collimator and control handle) a bucky table, a bucky wall stand and a high tension generator cabinet for general x-ray examinations.The csm3 ceiling suspension is attached to the longitudinal ceiling rails and can be freely moved longitudinally and transversely.The two longitudinal ceiling rails and the extension rails of the csm3 are fixed to the ceiling sub construction anchor rails with clamping blocks at about every 1300mm (51 inch).The sub construction will be installed by a contractor prior to system installation by philips.The philips field service engineer (fse) has investigated on site.It was noticed that both longitudinal ceiling rails have lowered to the extended rails by 5mm and causing the collision.The fse checked all torque settings and coupling bars for the longitudinal ceiling suspension rails and extended rails and no issues were found.Also checked the fse the bolts and fixings of the sub construction and nothing was found to be loose.The contractor company ¿rcl services¿ has sent engineers which mounted additional ceiling fixture to the rails where the longitudinal ceiling rail and the extension rails meet.After a few runs of the csm3 it can be concluded that the system is safe to use.Risk estimation revealed no unacceptable risk.The issue is further monitored and trended.The event was originally reported to the authorities as not enough information was available to make a definite reportability decision.Since that time, additional information was received which revealed that the event does not meet the criteria for reporting.
