Abstract
An ultrasound transducer patch (100) comprises an array of ultrasound transducers (20) mounted to a flexi-PCB (10) containing multiple tracks (12). Each transducer (20), or a sub-group of the transducers is electrically connected to first and second of the multiple tracks. The flexi-PCB (10) is configured, such as by virtue of cut-out portions (114, 414) or by inherent elasticity, to be bendable a out non-parallel axes. The enables the patch (100) to readily conform to a complex 3D surface such as a portion of a patient's face to ensure efficient transmission of ultrasound energy to a desired area of treatment.
Claims35
An ultrasound transducer patch, comprising:
- a flexible printed circuit board;
- and
- at least one transducer cluster comprising a plurality of transducers mounted to the flexible printed circuit board, wherein each of the transducers is operable to generate ultrasound having a wavelength, and wherein the transducers are arranged such that the transducer cluster has a width of about the wavelength of the ultrasound.
An ultrasound transducer patch, comprising:
- a flexible printed circuit board;
- and
- a plurality of transducer clusters each of which comprises a plurality of dual-frequency transducers mounted to the flexible printed circuit board, wherein each of the dual-frequency transducers is operable to generate ultrasound having a low frequency ultrasound component and a high frequency ultrasound component, and wherein the dual-frequency transducers are arranged such that each of the transducer clusters has a width of about the wavelength of the low frequency ultrasound component.
A system for delivering ultrasound to a three dimensional target surface, comprising:
- an ultrasound transducer patch that conforms to the target surface, comprising (a) a flexible printed circuit board and (b) a plurality of transducer clusters each of which comprises a plurality of transducers mounted to the flexible printed circuit board, wherein each of the transducers is operable to generate ultrasound having a wavelength, and wherein the transducers are arranged such that each of the transducer clusters has a width of about the wavelength of the ultrasound;
- and
- an electrical driver operable to drive each of the transducers in each of the transducer clusters.
