Evolution of DMD mode parameters over the course of pHIFU treatment and correlation to the highest grade level of tissue damage. The box graphs show (a) mode frequency, (b) temporal decay rate, and (c) average power of each DMD cluster for 60 HIFU pulses. Changes of (d–f) frequency and (g–i) temporal decay rate for bubble clusters (cluster 8–10) with respect to pHIFU pulse number. (j) Temporal decay rate at the last HIFU pulse, averaged across all bubble clusters from all HIFU exposures, for lesions with highest damage grades 2 and 3 (*p < 0.05).
