MRI RF SHEILDING 


The quality of an MRI image is based upon two things: MRI system technology and RF shielding. A good MRI system will generate a quality image, whereas a good RF shield will protect that image. These two components represent a major investment in time, money and ultimately a commitment to the patient.

MRI systems are distinguished in various ways. An open bore versus a closed bore or a 3T versus a 1.5T or smaller magnetic field are just two such examples. Because RF shields are not all alike they, too, are similarly distinguished. Copper or aluminum versus galvanized or steel; self supporting versus glue/staple to parent walls;

RF shielding protects the quality of the image created from your MRI system. If you take care to select your MRI system, you should also take care in selecting your RF shield.





RF SHEILDED BOXES  


TC-5981A is a shield box that can effectively shield RF interference signals during the testing of mobile communication terminals. TC-5981A offers stable and superior  shielding so it is suitable for manufacturing, service and R&D departments. This product has a built-in electromagnetic wave absorber (0.8~2.5GHz/absorption ratio: about 3~7dB).  For automation, it may be  opened/closed via RS-232C.

Features

»   High durability and outstanding shielding capacity
»   Automatic opening/closing/ fixture actions through air-compression (pneumatic) method.
