Tabulation of optimization times, compression times, and total number of matrices for pTx optimization done with VOPs using ϵ=2.5% and ϵ=15% and with uncompressed SAR matrices. Using VOPs with ϵ=2.5% comes with a significant penalty in compression time of 1193 seconds. Optimized SAR MIPs are shown and a significant SAR hotspot is seen when using ϵ=15%.
