Abstract: An ultrasound energy barrier for avoiding energy accumulation in a to-be-protected region during tumor treatment has a barrier element and a positioning element. The barrier element is attached to a body surface of an animal outside a to-be-protected region and a to-be-treated tumor in turn, the barrier element has an outline matched with the to-be-protected region to thus shield the to-be-protected region, so as to avoid energy accumulation in the to-be-protected region during an ultrasound focusing treatment of the to-be-treated tumor. The positioning element positioning the barrier element on the body surface during the ultrasound focusing treatment.
