A shared-housing ultrasound transducer and machine-vision camera system is disclosed for registering the transducer's x, y, z position in space and pitch, yaw, and roll orientation with respect to an object, such as a patient's body. The position and orientation are correlated with transducer scan data, and scans of the same region of the object are compared in order to reduce ultrasound artifacts and speckles. The system can be extended to interoperative gamma probes or other non-contact sensor probes and medical instruments. Methods are disclosed for computer or remote guiding of a sensor probe or instrument with respect to saved positions and orientations of the sensor probe.

The array-type scanning acoustic tomograph includes a selection unit to select the elements constituting a vibrator group that connects vibrator drive signals and reception signals.

A method and system for providing ultrasound treatment to a tissue that contains a lower part of dermis and proximal protrusions of fat lobuli into the dermis. An embodiment delivers ultrasound energy to the region creating a thermal injury and coagulating the proximal protrusions of fat lobuli, thereby eliminating the fat protrusions into the dermis. An embodiment can also include ultrasound imaging configurations using the same or a separate probe before, after or during the treatment. In addition various therapeutic levels of ultrasound can be used to increase the speed at which fat metabolizes. Additionally the mechanical action of ultrasound physically breaks fat cell clusters and stretches the fibrous bonds. Mechanical action will also enhance lymphatic drainage, stimulating the evacuation of fat decay products.

Techniques, systems, and devices are disclosed for synthetic aperture ultrasound imaging using a beamformer that incorporates a model of the object. In some aspects, a system includes an array of transducers to transmit and/or receive acoustic signals at an object that forms a synthetic aperture of the system with the object, an object beamformer unit to (i) beamform the object coherently as a function of position, orientation, and/or geometry of the transducers with respect to a model of the object, and (ii) produce a beamformed output signal including spatial information about the object derived from beamforming the acoustic echoes; a data processing unit to process data and produce an image of the object based on a rendition of the position, the orientation, the geometry, and/or the surface properties of the object, relative to the coordinate system of the array, as determined by the data processing unit.
