After issuing draft guidance almost 16 years ago, the FDA issued final guidance that clarifies data required for 510(k) submissions for solid state x-ray imaging devices.
The FDA anticipates a significant number of 510(k) submissions as SSXI technology continues to evolve and replace conventional film/screen x-ray devices.
The guidance clarifies the type of data needed to establish substantial equivalence to a previously cleared conventional radiographic film/screen and image intensifier based fluoroscopic and image recording systems.
SSXIs indicated for mammography do not fall within the scope of the guidance.
The devices covered by the guidance are solid state transducers that intercept x-ray photons and convert them into electrical signals that create visible images.
Product code 90 MQB has been established for SSXIs, and they are currently classified as Class II devices.
Sponsors should submit the following nonclinical information to the FDA to determine equivalence to a predicate device: physical characteristics; operational functions; functional characteristics; exposure characteristics; safety features; and test results.
Clinical information should also be included if the nonclinical information alone is not sufficient. The guidance notes two options for providing clinical information:
Submissions should also include a complete description of the quality assurance program recommended to the user as well as labeling information.
