1. A device for treatment of a patient by High-Intensity Focus Ultrasound, the device comprising:
a treatment head including a High-Intensity Focus Ultrasound emitting unit, for generating High-Intensity Focus Ultrasound pulses;
an imaging device;
a pump for circulating a fluid in a cavity between the treatment head and a contact surface of the device adapted to be brought into contact with skin of the patient;
a control unit for controlling operation of the imaging device and the pump; and
wherein the control unit is adapted for operating the fluid circulation at least in a second circulation mode different from a regular circulation mode, further wherein the control unit is adapted for switching to the regular circulation mode, which comprises switching the fluid circulation on again or increasing fluid flow when a Doppler imaging mode and/or an elastography mode is deactivated.
