Abstract
This invention discloses a phototherapy apparatus for biological tissue (preferably skin tissue) treatment. The phototherapy apparatus comprises one or more light sources and a built-in ultrasonic imaging module. The ultrasonic imaging module provides a high-resolution image of the biological tissue from its surface layer to a depth of a few centimeters. The image is utilized to optimize the phototherapy procedure in parameters such as light intensity, wavelength, spot size, divergence angle, duration, repetition rate, duty cycle, etc. and to evaluate the effectiveness of the phototherapy procedure.
Claims3
A method for non-invasive treatment of skin tissue of human or animal targets, the method comprising the steps of:
- providing at least one light source to produce light radiation in one or more wavelengths, wherein the light radiation is non-invasively applied or directed to the skin tissue to be absorbed thereof for sterilization, bio-stimulation, and/or photo-rejuvenation;
- and
- providing a high frequency ultrasonic imaging module, operatively coupled to the light source, to provide a high-resolution ultrasonic image revealing inner structural information of the skin tissue, wherein the inner structural information of the skin tissue is utilized to control and optimize a plurality of parameters of the light source and to evaluate the effectiveness of the phototherapy procedure;
- wherein the ultrasonic frequency of the high frequency ultrasonic imaging module ranges from about 20 MHz to about 100 MHz.
