As
an alternative sonication method in magnetic resonance guided high intensity
focused ultrasound treatment, volumetric sonication method with feedback
control under volumetric MRI thermometry for the ablation of uterine fibroids
was presented. This method efficiently utilizes the inherent heat diffusion
by electronically switching the focal point between a number of predetermined
locations situated at outwards-moving concentric circles with diameters of
upto 16 mm. A significant improvemet in symptom severity score at 1month
follow-up over baseline was observed. Volumetric treatment allows for
complete and uniform cell coverage, and the delivery of optimal thermal dose
significantly minimizing the risk of overtreatment.
