Stanford researchers at the Ferrara Lab have developed a volumetric ultrasound imaging that uses a motion controller to realize 3D imaging. This invention introduces a new transducer architecture with significantly improved image resolution. The prototype has been tested on phantom with plans for human trials.

Figure description - The ring array assembled by eight L7-4 linear arrays and the orientation of the image grid.
In one embodiment, the invention uses a 1024-element matrix array transducer combined with 3D printed manifold to create arrays of calibrated and aligned transducers. A motorized system is incorporated to scan large regions of a subject under test, to enable use of software for 3D imaging and 3D passive acoustic mapping, and for combining imaging and therapy.
