The dStream (dS) Base coils are lightweight, 8-channel receive only, phased-array coil that are designed to be used independently or in combination with the dS Head or dS HeadNeck coil. The dS Base coil can be used for extremities and pediatric examinations or can be combined with the dS Posterior coil which is integrated in the patient support of the compatible MR Systems4 for total spine imaging. The dS Base coil can stay on the table for most examinations without exchanging coils, thereby improving workflow. These coils are available in both 1.5T and 3.0T and are connected with the flex connect socket of the compatible MR System.
A radio-frequency (RF) coil acts as a transmitter, receiver, or both a transmitter and receiver of RF pulses necessary for diagnostic magnetic resonance imaging (MRI) procedures. It is used to enhance image resolution by improving signal to noise characteristics. There are two main kinds of RF coils: volume coils (which surround the part of the body being imaged) and surface coils (which are placed and secured directly on or under an area of interest). This group of devices includes a variety RF coil designs and configurations including, e.g., surface coils, phased array coils, paired saddle coils, Hemholtz pair coils or bird cage coils.
