Study Arms (1)
Targeted microwave ablation
EXPERIMENTALTargeted microwave transrectal or transperineal ablation of the prostatic index tumor using MRI-transrectal image registration and OBT fusion
Interventions
Targeted ablation of the index tumor with microwaves, by using either a transperineal or a transrectal approach
