Safety guidelines are provided by IEC to set maximum
temperature and maximum SAR achievable during MRI scans.
SAR-based safety evaluation of multichannel transmit
systems has been accelerated using Virtual Observation
Points to enable rapid RF safety monitoring and RF pulse
design based on SAR constraints. In this work, using a
matrix formalism to compute temperature, we propose a
method to identify temperature based VOPs. Temperature
based VOPs enable fast parallel transmit RF pulse design
with iterative or non-iterative methods based on strict
temperature constraints.
