Title:
SURFACE STATIONARY RF ARRAY COIL STRUCTURE FOR MULTI-MODALITY MRI/PET IMAGING
Document Type and Number:
WIPO Patent Application WO/2015/009598
Kind Code:
A3
Abstract:
A stand-alone MR or hybrid PET-MR imaging system incorporating a surface stationary RF coil structure is disclosed. The imaging system includes a support assembly comprising a cradle to accommodate a subject and a bridge to receive the cradle and provide for translation therealong to enable an acquisition of imaging data. An RF coil structure is positioned between the bridge and the cradle, and includes a base portion, a cover portion, and an array of RF coil elements positioned on the cover portion. The cover portion includes contoured features that enable placement of RF coil elements in proximity to a subject and to provide a constant and uniform gap between the RF elements and the cradle. The RF coil structure also includes structural elements that support the cradle when rolling over the array of RF coil elements without deforming the RF coil elements.
