Combined 2d pulse-echo ultrasound and optoacousticsignal for glaucoma treatment

摘要

The present invention provides an apparatus and method for combining image that reflects the pulse echo ultrasound properties together with the optoacoustic properties of the tissue as a function of spatial location. According to one aspect of the invention, the apparatus for guiding a laser beam to a predetermined position and follow up treatment at the predetermined position comprises an ultrasound system and ultrasound probe adapted to provide real-time 2D ultrasound image, attachment means attached to the ultrasound probe allowing a laser beam to be directed to a predetermined position relative to the ultrasound probe, wherein said laser beam generates radiation that is adapted to be directed to the predetermined position and an array of ultrasound receivers including at least three receivers provided in the attachment means, wherein the array of ultrasound receivers is adapted to sense a signal generated from the radiation.
