Abstract: A method for acoustic tomography within a patient may include generating a focused ultrasonic signal using a transducer is provided; the ultrasonic signal forming a path within the patient. The method includes directing the ultrasonic signal on a spot within the patient; scanning the spot in a predetermined pattern about a volume within the patient; receiving an ultrasonic echo in the transducer; converting the ultrasonic echo into a voltage; selecting a frequency band from the voltage; amplifying the voltage in the selected frequency band with a processing circuit; and generating an image of the volume within the patient structure utilizing the amplified voltage. A method for recanalization of a blood vessel including the above acoustic tomography steps is also provided.
