Abstract
The invention relates to a device (1) and a method to avoid artefacts in second circulation mode imaging during ultrasound treatments of the human body (P). Specifically and amongst other effects, the invention provides a way to adequately control, in particular turn on and off, the fluid circulation (12) in a cavity (7) such as to avoid artefacts while still enabling practical imaging.
Claims20
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.
A method for treatment of a patient by High-Intensity Focused Ultrasound, the method comprising the following steps:
- treating a target of the patient with High-Intensity Focused Ultrasound pulses;
- circulating a fluid in a cavity between a treatment head and a contact surface of a device adapted to be brought into contact with skin of the patient in a regular circulation mode;
- monitoring the target with an imaging device operating temporarily in a Doppler imaging mode and/or elastography mode;
- and
- changing the circulation of the fluid to a second circulation mode at least temporarily during monitoring in the Doppler imaging mode.
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;
- and
- a control unit for controlling operation of the imaging device and the pump wherein the control unit is adapted for operating the fluid circulation at least in a second circulation mode different from a regular circulation mode wherein the control unit is adapted for switching to the second circulation mode, which comprises stopping the fluid circulation, when a Doppler imaging mode and/or an elastography mode is activated.
