Abstract
The invention relates to a treatment probe for focused ultrasound including a probe body, which is mounted in rotation around an axis; an elongated treatment transducer with a focused ultrasound emission acoustic axis, which is more or less the same as the rotation axis of the probe body; and an imaging transducer, the imaging plane of which contains the acoustic axis of the treatment transducer. The inventive probe can be used to provide a simple treatment. The probe body can be rotated around the axis in order to vary the direction of the imaging plane without moving the focus, which always remains in the imaging plane. The treatment transducer can be extended in order to provide safer treatment in relation to the organs to be treated and without risk of damaging the fragile surrounding organs.
