GE Healthcare (www.gehealthcare.com) introduces the Signa^® MR750 3.0 T, built around GE's third-generation short-bore superconducting 3.0 T magnet. Whole-body gradients deliver 50 mT/m gradient field on each axis simultaneously and yield a slew-rate of 200 T/m/s when combined with OpTix optical radiofrequency technology. The system provides higher accuracy and more reproducible scans with up to 60 percent more anatomical coverage and resolution per unit time, 27 percent more signal-to-noise ratio and faster reconstruction speeds.

MR750 3.0 T offers high homogeneity for excellent results even in large or off-center field-of-view imaging, fat saturation techniques and high-performance applications such as cardiac, functional MR imaging, diffusion tensor imaging and spectroscopy. Other features include real-time specific absorption rate optimization, heat extraction gradient architecture for faster acquisitions and fewer slowdowns, accelerated parallel imaging and anatomy-optimized radiofrequency coils and arrays.

FDA CLEARANCE

Automated Contrast Delivery System

Covidien Imaging Solutions (www.covidien.com) has received FDA approval for its contrast delivery system with radiofrequency identification (RFID), designed to reduce the risk of medical errors.

Combining unit-dose Ultraject^TM prefilled contrast media syringes with Optivantage^TM DH power injectors, the system captures, stores and transmits data between the syringe and the injector using RFID transponders or "tags." This better ensures that each patient receives the prescribed drug and dose. The interface allows the injector to physically alter the RFID label on a syringe once it is used and automatically prevents injection of contents from a previously used RFID-labeled syringe, substantially reducing the probability of life-threatening air injections or air embolisms. Covidien's system also indicates if the drug in an RFID-labeled syringe is past its expiration date.

FDA CLEARANCE

MR Perfusion Software

Imaging Biometrics (www.imagingbiometrics.com) has received FDA clearance for its IB Neuroâ„¢ 1.0 MR perfusion software. IB Neuro analyzes dynamically acquired MR datasets and generates parametric maps of the brain that include relative cerebral blood volume (rCBV), cerebral blood flow (CBF) and mean transit time. The software is currently available for the aycan workstation OsiriXPRO and OsiriX applications. IB Neuro is DICOM compliant and easily integrates into existing viewers, CAD workstations and PACS.

IB Neuro displays the dynamic MR signal time course for any chosen brain location. It automatically corrects for artifacts in rCBV maps caused by contrast agent leakage, allows interactive selections of arterial input functions for CBF and normalizes perfusion parameters to normal appearing white matter to facilitate comparisons.

NEW PRODUCT

Custom-Moldable Head Support

CIVCO Medical Solutions (www.civco.com) introduces the Individual Head Support for customized head and neck positioning during radiation therapy treatment and diagnostic procedures. Using specially shaped impression foam combined with fabric-coated thermoplastic, the Individual Head Support allows clinicians to customize position and support to each patient while minimizing movement.

The flexibility of the heated thermoplastic allows easy molding of the impression foam to the individual patient's anatomy, maximizing both patient comfort and reproducibility of positioning. Once cooled, the thermoplastic binds the foam to the molded shape.
