Wireless MRI data transfer with an Integrated/Radio-frequency Wireless Spiral Coil Design for low-field portable MRI over cellular networks.

Motivation: Wireless transmission of MRI data acquired with low-field portable MRI scanners within EMT vehicles over cellular/satellite networks drastically decreases time between stoke onset and imaging for improved patient outcomes. Goal(s): Our goal is to enable wireless communication with an iRFW coil design for simultaneously imaging and wireless cellular/satellite data transfer from within the scanner and an EMT vehicle. Approach: iRFW-Cellular simulations within a portable 70 mT scanner are performed to evaluate its SNR and far-field gain patterns for wireless communication. Results: The iRFW-Cellular simulations showed a uniform SNR in the head and gain patterns appropriate for the wireless transmission of MRI data. Impact: The iRFW-Cellular spiral coil design potentially enables wireless MRI data transfer from a low-field portable MRI scanner inside, or out, of an EMT vehicle for better stroke onset to imaging times.
