Model R225 ACS Automatic X-RAY Collimator is intended for use in diagnostic radiographic/fluoroscopic applications.
Device Story
The Model R225 ACS is a multilayer, square-field automatic X-ray collimator used in diagnostic radiographic and fluoroscopic systems. It functions by controlling the X-ray beam geometry via stepper motors that adjust internal shutters and an additional filter. The device features a mounting plane at 80 mm from the focus. A microprocessor circuit manages the stepper motors to provide stepless adjustment of square field dimensions at variable focus-to-film distances (FFD/SID). Field dimensions are adjusted via manual knobs on the front panel. The device is operated by clinical staff in a diagnostic imaging environment. By automating beam limitation, it ensures precise X-ray field sizing, which helps optimize radiation exposure and image quality for the patient.
Clinical Evidence
Bench testing only. No clinical data was required or provided. The device was validated through laboratory and safety testing to confirm it meets US performance standards for diagnostic X-ray beam-limiting devices.
Technological Characteristics
Multilayer, square-field automatic collimator. Features stepper motor-driven shutters and filter. Microprocessor-controlled adjustment of field dimensions at variable FFD/SID. Mounting plane at 80 mm (3.15") from focus. Manual adjustment knobs provided. Conforms to US Performance Standards for diagnostic X-ray beam-limiting devices (21 CFR 892.1610). CSA listed for medical device safety.
Indications for Use
Indicated for use in diagnostic radiographic and fluoroscopic applications for patients requiring X-ray imaging.
Regulatory Classification
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.

#### 1. Identification of the Device:
Proprietary-Trade Name: Model R225 ACS Automatic X-RAY Collimator Classification Name: collimator, automatic, radiographic, Product Code IZW Common/Usual Name: Automatic X-Ray Collimator.
- Equivalent legally marketed devices: K072780, Ralco Model R302DACS Automatic Collimator. 2.
- Indications for Use (intended use): Intended for use in diagnostic/fluoroscopic applications. 3.
- Description of the Device: This x-ray collimator Multilayer, square-field, automatic collimation 4. system. Stepper motors control the movements of shutters and the additional filter. There is a mounting plane at 80 mm (3.15") from the focus. A microprocessor circuit controls the stepper motors and provides the stepless adjustment of the square field dimensions at variable FFD (SID). The field dimensions may be decreased and increased to the set value by two knobs placed on the collimator front panel.
- Safety and Effectiveness, comparison to predicate device. The results of bench, safety test, and 5. laboratory testing indicates that the new device is as safe and effective as the predicate device. The predicate employs a round field, same as our new device. The new device conforms to US Performance Standards and is CSA Listed to US Standards for safety for medical devices.
- Conclusion: After analyzing both bench and safety testing data, it is the conclusion of Ralco that the . 6. Model R225 ACS is as safe and effective as the predicate device, has few technological differences, and has identical indications for use, thus rendering it substantially equivalent to the predicate device.
Image /page/0/Figure/10 description: The image shows two different devices, labeled "Predicate" and "R225 ACS". Both devices are cube-shaped with control panels on the front. The "Predicate" device has a keypad and knobs, while the "R225 ACS" device has a display screen, buttons, and knobs.

#### Dear Mr. Kamm:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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 (PMA), it may be subject to 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.
