Combination ultrasound-phototherapy transducer
View Patent ↗A soundhead of a treatment device is provided that enables a volume of tissue located beneath the soundhead to simultaneously receive ultrasound and light stimulation. According to one embodiment, the soundhead includes an ultrasound transducer, a light source, and a faceplate extending across a face of the transducer for providing a tissue contacting and ultrasound energy coupling surface of the soundhead. The faceplate is transparent or translucent to the light generated by the light source. Alternate embodiments including externally mounted light sources are also disclosed.
1. A treatment device, comprising:
a soundhead having an ultrasonic transducer configured to produce ultrasound energy;
a layer comprised of an opto-acoustic material adjacent said ultrasonic transducer; and
at least one light source disposed outside of a periphery of said ultrasonic transducer for directing light laterally into said layer;
said opto-acoustic material configured to provide acoustic coupling of the ultrasound energy of said ultrasound transducer and to reflect or diffuse the light from said light source to underlying tissue;
whereby, in use, the treatment device enables a volume of the underlying tissue to simultaneously receive ultrasound and light stimulation from said ultrasonic transducer and said light source.
2. The treatment device of claim 1 , wherein said soundhead includes a faceplate extending across a face of said transducer between said transducer and said layer.
3. The treatment device of claim 2 , wherein said faceplate is transparent or translucent to said light produced by said light source.
4. The treatment device of claim 1 , wherein said layer and said light source are contained with a housing that is removably connectable to said soundhead.
