摘要：
Systems, methods, and computer readable media for high-frequency contrast imaging and image-guided therapeutics are disclosed. According to one aspect, a method for high frequency contrast imaging and image-guided therapeutics includes: providing ultrasound of a first frequency bandwidth, directed toward the volume to be imaged, the volume containing a carrier having non-linear acoustical properties, wherein the ultrasound of the first frequency bandwidth causes the carrier to generate ultrasound of a second frequency bandwidth that is different from the first frequency bandwidth； receiving, from the volume to be imaged, ultrasound of the second frequency bandwidth； and using the received ultrasound of the second frequency bandwidth to generate an image of the volume to be imaged, wherein the components of the second frequency bandwidth that are detected are of a frequency greater than 20 MHz. According to another aspect, ultrasound at a first frequency bandwidth enables imaging of a target, and ultrasound at a second frequency bandwidth mediates drug or gene delivery to a portion of the target, as guided by the image provided by the first frequency.
