Sterile RF coil arrangements for use in magnetic resonance imaging are provided. The sterile coil arrangements can be formed by spraying or coating a curable liquid onto an RF coil housing and allowing the liquid to cure or dry to form a continuous sterile layer on the coil housing. The thickness of the sterile layer can be between 100 and 1000 micrometers. The curable liquid can include an antimicrobial or antibacterial agent, such as silver ions or triclosan, to better maintain sterility of the coil arrangement. The curable liquid can be selected such that it adheres to the housing when cured and is also removable without leaving residue behind.

Sterile RF coils for MR imaging systems

A configurable coil arrangement for use with MRI-guided procedures is provided that facilitates optimal imaging for both pre-procedure planning and imaging of the target sites during the procedure. The coil arrangement includes a plurality of connected coil elements. Spacers connecting the coil elements can be adjustable and/or deformable to provide one or more openings in the coil arrangement of optimal size for accessing the subject within the imaged region. Individual coil elements can also be removed to provide access openings during such procedures, or left in the array for improved pre- and post-procedure image quality. The MRI system can be configured to detect configurations of the coil arrangement and modify imaging parameters to optimize image quality.

Magnetic resonance imaging coil with adjustable opening

A magnetic resonance imaging system and method are provided that include user control of certain functions using physical gestures, such as hand motions or the like. The gesture control aspects can include one or more cameras, and a processor configured to detect and recognize gestures corresponding to predetermined commands and to provide signals to execute the commands. A verification switch, such as a foot switch, can be included to improve safety and reliability of the gesture control aspects. This switch can be used to activate the gesture detection aspects and/or to confirm a recognized gesture command prior to its execution.
