The Philips Nicol Collimator Family was cleared through the FDA 510(k) pathway on March 15, 1999. It is manufactured by Philips Medical Systems and classified as a Class 2 device.
What It Is
The Philips Nicol Collimator Family is a series of devices designed to control the size and shape of X-ray beams during radiological procedures. Collimators are essential in reducing patient exposure to unnecessary radiation and improving image quality by focusing the X-ray beam on the area of interest. This device is particularly useful in procedures requiring high precision, such as interventional radiology.
FDA-Cleared Indications
- Use with compatible X-ray imaging systems to limit and shape the primary X-ray beam.
- Use during diagnostic and interventional radiographic or fluoroscopic procedures requiring controlled radiation fields.
- Use to support imaging of a selected anatomical region while reducing irradiation of areas outside the region of interest.
Clinical Applications
- Field-size control during fluoroscopically guided vascular procedures.
- Beam limitation during diagnostic radiography and fluoroscopy.
- Imaging support during interventional procedures, including procedures requiring image guidance for targeted treatment.
- Adjustment of the X-ray field to match the anatomy being examined.
Practical Considerations
- The collimator must be used with a compatible X-ray tube, fluoroscopy unit, and imaging system; compatibility depends on the specific model and system configuration.
- Available field sizes, adjustment ranges, light-field alignment, and mounting characteristics vary across the Nicol Collimator Family.
- This is an X-ray accessory, not an MRI device. It should not be taken into the MRI scanner room unless the specific model has been evaluated and labeled as MR Safe or MR Conditional.
- Operators should verify field alignment, shutters, filtration, and system calibration according to the manufacturer’s instructions and institutional quality-control procedures.
- The device does not eliminate radiation risk; dose optimization, shielding, distance, and fluoroscopy-time reduction remain necessary.
