This limits the potential for radiation to the general population in the exam area. This device is intended to be used in the radiology. This device is operated and used by Physicians and X-ray technologist. The object of this device is total patient populations. ## Device Story Beam limiting device (collimator) R-20J; used with x-ray generator and tube; restricts radiation emission to specific field of view; reduces radiation exposure to patients and staff in radiology settings; operated by physicians and x-ray technologists; mechanical adjustment of aperture; provides radiation field control; benefits patient by minimizing unnecessary radiation exposure. ## Clinical Evidence No clinical data; bench testing only. ## Technological Characteristics Mechanical beam-limiting collimator; designed for integration with x-ray generators and tubes; manual or motorized aperture adjustment; no software or electronic processing components. ## Regulatory Identification A diagnostic x-ray beam-limiting device is a device such as a collimator, a cone, or an aperture intended to restrict the dimensions of a diagnostic x-ray field by limiting the size of the primary x-ray beam. ## Special Controls *Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9. ## Predicate Devices - Beam limiting device R-30H ([K031771](/device/K031771.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act): 21 CFR 1000-1050. {1}------------------------------------------------ This Ictter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter: | 21 CFR 876.xxxx | (Gastroenterology/Renal/Urology) 240-276-0115 | | |-----------------|-----------------------------------------------|--------------| | 21 CFR 884.xxxx | (Obstetrics/Gynecology) | 240-276-0115 | | 21 CFR 892.xxxx | (Radiology) | 240-276-0120 | | Other | | 240-276-0100 | Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
