"The Maryland Center for Advanced Imaging Research (MCAIR) houses a research dedicated 3.0 Tesla Siemens BioGraph mMR scanner that is equipped with a state of the art MRI and PET system. 

The Prisma has state of the art parallel imaging technology with 64 receive channels, and a 64-channel head radio-frequency (RF) coil. Several customized RF coils are also available that allow optimal imaging of small and large animals. The Prisma scanner has audio-visual presentation (rear-projection) to facilitate functional MRI protocols, and handheld button response boxes are present for the study participants to provide response during a functional paradigm.  Both E-Prime and Presentation programs are available to the users to design their functional paradigms. A mock scanner is available for research participant training.

The scanning room has been designed with optimum RF shielding.  All electronic equipment brought into the scan room is passed through a penetration panel which is conveniently located at the scanner console.  The Center also features power conditioning to enhance MRI temporal stability.  Preventive maintenance that involves measurement of temporal stability and noise characteristics are done on a monthly basis above and beyond what is performed by the vendors of the respective machines.  A 100 Kilowatt uninterruptible power supply (UPS) provides continuous conditioning of the electrical power for the scanners, shielding the gradient and radio-frequency amplifiers from any fluctuations in building power.  

A strong research relationship exists between MCAIR and scientists from Siemens Healthineers, which facilitates progress on ongoing research projects.  Several MR physicists are trained on the use of the IDEA pulse sequence environment and the ICE image reconstruction environment available on the Siemens scanner."
