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.

Abstract: The present invention relates to use of co-registered data to virtually recreate a section of a vessel in an external image, in which the section of the vessel cannot be imaged using an external imaging modality. In certain aspects, a method of the invention includes obtaining external imaging data of a vessel, wherein data representing a specific portion of the vessel is absent from the external imaging data, obtaining intraluminal imaging data of the specific portion of the vessel, and co-registering the external imaging data with the intraluminal imaging data to construct an external image of the vessel that includes the specific portion of the vessel.
