MR Safe What does this mean?

MR Safe – an item that poses no known hazards in all MRI environments. Using the terminology, “MR Safe” items are non-conducting, non-metallic, and non-magnetic items such as a plastic Petri dish. An item may be determined to be MR Safe by providing a scientifically based rationale rather than test data.

MR Conditional – an item that has been demonstrated to pose no known hazards in a specified MR environment with specified conditions of use. “Field” conditions that define the MR environment include static magnetic field strength, spatial gradient magnetic field, dB/dt (time rate of change of the magnetic field), radio frequency (RF) fields, and specific absorption rate (SAR). Additional conditions, including specific configurations of the item (e.g., the routing of leads used for a neurostimulation system), may be required.

MR Unsafe – An item that is known to pose hazards in all MRI environments. MR Unsafe items include magnetic items such as a pair of ferromagnetic scissors.

Frequently Asked Questions

What is the MRI ACR Phantom, Large used for?

The MRI ACR Phantom, Large is used to perform quality assurance and performance testing on MRI scanners to maintain compliance with ACR (American College of Radiology) accreditation requirements. It helps evaluate key imaging parameters such as spatial resolution, slice thickness, image uniformity, geometric distortion, and signal-to-noise ratio (SNR). Using this phantom ensures your MRI system produces consistent, high-quality diagnostic images and meets ACR, AAPM, and IPEM standards.

Is the MRI ACR Phantom, Large MR Safe or MR Conditional?

This phantom is MR Safe — it contains no metallic or conductive materials and poses no known hazards in any MRI environment. It can be safely used in MRI Zones I–IV, including directly inside the bore, without affecting the magnetic field or image quality. Its materials and design meet ASTM F2503 guidelines for MR Safe labeling.

What tests can I perform with this ACR MRI Phantom?

The phantom is designed for a full range of MRI system performance and calibration tests, including geometric distortion and spatial resolution, slice thickness and interslice gap accuracy, low-contrast detectability, image uniformity and SNR measurements, bandwidth and water–fat shift evaluation. It’s the standard tool for ACR accreditation, acceptance testing, and routine QA of MRI systems.

Does the MRI ACR Phantom come with testing instructions or calibration support?

Yes. Each phantom includes a comprehensive manual with step-by-step instructions for setup, image acquisition, and test interpretation. The guide follows protocols from the ACR MRI Accreditation Program and relevant AAPM and IPEM reports, so technologists and physicists can document results accurately and consistently.

How is the MRI ACR Phantom, Large shipped, and what are the ordering details?

MRI Med typically ships stocked products within 48 business hours (Monday–Friday, PST). The phantom measures 8 inches in diameter and is packed securely for transit; a protective carrying case (PC-138) is available separately. An import tariff surcharge may apply at checkout. Returns are accepted for unused items within 30 days of shipment with prior approval. Any freight damage or shortages must be reported within 48 hours to MRI Med and the carrier.
