Accusorb MRI RF Shielding Material

RF Shielding Material

Fabric offers more than -80dB isolation in transmission from below 50 MHz to over 100 GHz and -15dB in absorption from 1 to 18 GHz. Resultant suppression of artifact images allows for enhanced resolution with the added benefit of reduced RF exposure.

This device is lead free and offers no X-Ray protection.

Use of advanced RF shielding, absorbers and thermal barriers prevent heating. The patient remains comfortable during the scan.

Safety Note:
This material is not intended for use on patients with
metallic, electronic, magnetic or mechanical implants, devices or objects.

This material blocks RF. It does not block Electromagnetic Energy.

This material will not protect or shield an implant, device, or product during a scan.
This material is to be used only to shield parts of the anatomy of patients who do not have implants.
If a patient is not safe in the MRI scanner without this material the patient will not be safe in the MRI with this material.

"We have found the RF Blankets invaluable for several years of scans. By wrapping the opposite lower extremity when scanning a knee, calf, thigh, for or ankle, we can use small FOV's with out worrying about phase wrap. Similarly, in the chest or abdomen studies we wrap both arms with the small RF Blankets for those patients that are unable to hold their arms over their head. This allows for shorter breath-hold scanning, which in some cases for the elderly and/or extremely ill, means that completion of a successful scan."

"Not having wrapping from adjacent anatomy on images is very important in clinical MRI. Accusorb RF Shielding products prevent the technologist from putting patients in uncomfortable positions to avoid wrapping of anatomy. It is very Simple to use, just cover the areas that you do not wish to see and the anatomy disappears. This saves lots of energy and time for technologists."

We have been using the Magmedix RF Blanket for about two years. Primarily, we incorporate the Blanket for orthopedic cases in our 1.5 Tesla scanners. The Blanket will also work well for Angio cases if the Coronal plane is the desired view for the MRA. We have been using both versions of the RF Shield (blanket): one form is a large 36” x 36” blanket shaped device. The other form is the arm shaped RF Shields, which, by the way, can also be used to cover the legs on smaller patients (children).

All of our testing of this unique device has been on the 1.5 Tesla GE magnet with extremely encouraging results. Use of the fabric (whether in the blanket or arm forms) can help to lessen the time of sequences by eliminating the need to add No Phase Wrap to the sequence protocol. The device totally removes the non imaged limb from view on the exam, and from the sequences. This feature is especially necessary when trying to image a hand on a young person who is in the supine position, with the hand down by the side, next to the body. In this case, one would place the fabric over the hips, flank, abdomen of the patient. Doing this will eliminate wrap from the side of the body closest to the hand or wrist that is being imaged. Likewise, for the imaging of the unilateral knee, the RF Shield provides the technologist with the assurance that there will be no wrapping artifact from the non-imaged knee.

Any device that will consistently reduce the time factor in orthopedic/body MR exams is definitely a most valuable addition to any MRI department.
