Clinical Performance Data The ERI Portable X-ray System has undergone comprehensive non-clinical design verification and validation testing, including assessments of Electrical Safety and performance. The results confirm that the device's design is appropriate and effective for its intended use. Additionally, clinical trials were conducted to compare the imaging results of the ERI Portable X-ray System with those obtained from commercially available X-ray devices. These trials demonstrated that the image quality produced by the ERI system is on part with that of the comparison devices, supporting its substantial equivalence as a portable X-ray system. # IX. Conclusions The Energy Resources International ERI Portable X-ray System has the same intended use and same basic technology as the predicate device, thus is able to achieve the same effectiveness and safety as the predicate device. The ERI Portable X-ray System contains in some combination similar features and design as the predicates. Other differences include device design such as exposure time, size and user interface. The subject device is substantially equivalent to the predicate device with its intended use, mechanical and electrical performance as described.
