FDA Finalizes Two Guidances to Align X-Ray Imaging Devices With International Standards

FDA Finalizes Two Guidances to Align X-Ray Imaging Devices With International Standards

The US Food and Drug Administration (FDA) on Tuesday finalized two guidance documents related to harmonizing X-ray device performance standards with international standards, and federal performance standards for fluoroscopic equipment.

On the harmonization front, FDA is looking to align performance standards prescribed by the Electronic Product Radiation Control (EPRC) with standards from the International Electrotechnical Commission (IEC) to help to ensure more efficient and consistent regulatory review of submissions for X-ray imaging equipment.

“FDA has determined that industry conformance to certain IEC standards would provide, at a minimum, the same level of protection of the public health and safety from electronic radiation as certain EPRC regulatory standards,” the agency said. The 6-page guidance finalized a draft from August 2016.

But because a recently proposed rule would eliminate the reporting requirements for X-ray imaging devices, FDA determined that the proposed policy outlined in the draft guidance, which stated that X-ray imaging devices that conform to IEC standards would be considered to have met the EPRC reporting requirements, should be removed from the final version.

“This decision was made to avoid the confusion inherent in establishing an interim procedure that would shortly be superseded by the final rule,” FDA said. “However, as stated in section V. of the guidance, FDA believes that submission of a declaration of conformity to the appropriate standards, and model identification as required by 21 CFR 1002.10(a) and (b), in a product report, would be sufficient to meet the requirements of a product report under 21 CFR 1002.10, thus reducing duplication.”

But FDA also cautions industry that failing to meet any requirements relating to the emission of electronic product radiation of an IEC standard, corrigenda or amendment to which a manufacturer declares conformance is an electronic product defect and is cause for notification and repurchase, repair or replacement.

The other 6-page guidance, which finalizes a draft from September 2014, addresses three aspects of the federal performance standard for fluoroscopic equipment. The three aspects include: Fluoroscopic Irradiation Time, Last-Image Hold and Emergency Fluoroscopy Mode.

Organ Preservation Devices

In addition to the two guidance documents on X-ray devices, FDA also finalized another guidance on Tuesday providing recommendations regarding best practices for utilizing animal studies for the evaluation of organ preservation devices.

“FDA recognizes that best practices for conducting animal studies to evaluate organ preservation devices are evolving with the rapid advancements in such technologies. This guidance is not intended to be comprehensive or prescriptive. Instead, it aims to highlight FDA's initial thoughts on how animal transplant models can be utilized to evaluate organ preservation technologies, with careful considerations of regulatory least burdensome principles,” the agency said.
