Abstract
Embodiments of a dermatological cosmetic treatment and/or imaging system and method adapted to alter placement and position of multiple cosmetic treatment zones in tissue from ultrasound beams from a transducer, simultaneous multi-focus therapy at multiple depths, and/or dithering ultrasound beams from a transducer to alter placement and position of multiple cosmetic treatment zones in tissue. The system can include a hand wand, a removable transducer module, and a control module. In some embodiments, the cosmetic treatment system may be used in various cosmetic procedures.
Claims20
An ultrasound treatment system for dithering a focus point from an ultrasound transducer at one or more depths, comprising:
- an ultrasonic probe comprising an ultrasound transducer with a single transduction element adapted to simultaneously apply ultrasound to tissue,
- wherein the ultrasound transducer is poled with at least a first poling configuration and a second poling configuration,
- a control module coupled to the ultrasonic probe for controlling the ultrasound transducer,
- wherein the control module modifies a spacing between a first focal zone and a second focal zone via dithering, wherein the dithering comprises modulation of a frequency as a frequency swing about an aperture center frequency during operation such that the spacing between the first focal zone and the second focal zone varies over time while the ultrasound is simultaneously applied to the tissue, and
- wherein the dithering comprises electronically scattering a position of a beam focus point at the first focal zone and electronically scattering the position of the beam focus point at the second focal zone over time, and wherein the dithering enlarges a treatment area associated with each of the first focal zone and the second focal zone.
A method of simultaneously dithering a focused ultrasound beam at one or more depths, comprising:
- providing an ultrasonic probe comprising a single transduction element and a control module,
- wherein the single transduction element is adapted to apply ultrasound to tissue at a first focal zone and a second focal zone at a focal depth,
- wherein the control module is coupled to the ultrasonic probe for controlling the single transduction element, and
- dithering the focal zone via modulation of a frequency to alter a size of the focal zone at the tissue, wherein dithering comprises modulation of a frequency as a frequency swing about an aperture center frequency during operation such that the spacing between a first focal zone and a second focal zone varies over time while the ultrasound is simultaneously applied to the tissue, and
- wherein the dithering comprises electronically scattering a position of a beam focus point at the first focal zone and electronically scattering the position of the beam focus point at the second focal zone over time, and wherein the dithering enlarges a treatment area associated with each of the first focal zone and the second focal zone.
