    Abstract: A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.

Other factors may be used instead or in addition to tissue response at the focal region. Relative proximity of the sub-apertures to a lesion, angular distribution of the sub-apertures, shape or size of the sub-aperture focal regions as compared to the tissue to be treated, or combinations thereof may be used. Once selected, the relative weight for each sub-aperture may be adjusted based on measured tissue response for each sub-aperture, such as to provide more equal treatment contribution from different sub-apertures.

    Abstract: In one embodiment, an ultrasound imaging method comprises: providing a probe that includes one or more transducer elements for transmitting and receiving ultrasound waves; generating a sequence of spatially distinct transmit beams which differ in one or more of origin and angle; determining a transmit beam spacing substantially based upon a combination of actual and desired transmit beam characteristics, thereby achieving a faster echo acquisition rate compared to a transmit beam spacing based upon round-trip transmit-receive beam sampling requirements; storing coherent receive echo data, from two or more transmit beams of the spatially distinct transmit beams; combining coherent receive echo data from at least two or more transmit beams to achieve a substantially spatially invariant synthesized transmit focus at each echo location; and combining coherent receive echo data from each transmit firing to achieve dynamic receive focusing at each echo location.

  • Publication number: 20140073924
    Abstract: A method for generating a composite image using an intravascular imaging device includes receiving reflected echo signals from at least one transducer along a first of a plurality of radial scan lines. The received echo signals are passed through a plurality of signal processing channels to form a plurality of filtered signals. The filtered signals include a high-resolution tissue structure signal and at least one first pre-blood-flow-mask signal. High-resolution tissue structure signals are processed to form a high-resolution tissue structural image. First pre-blood-flow-mask signals are cross-correlated with second pre-blood-flow-mask signals from an adjacent radial scan line to form blood-flow-mask signals. Blood-flow-mask signals are processed to form a blood-flow mask.

  • Patent number: 8663112
    Abstract: A method can include targeting a region of interest below a surface of skin, which contains fat lobuli and delivering ultrasound energy to the region of interest. The ultrasound energy generates a conformal lesion with said ultrasound energy on a surface of a fat lobuli. The lesion creates an opening in the surface of the fat lobuli, which allows the draining of a fluid out of the fat lobuli and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.

  • Patent number: 8657751
    Abstract: An ultrasound diagnostic apparatus includes a transmission and reception circuit which electronically scans with a transducer array in an ultrasound probe for acquiring two-dimensional image data; an image producer which produces a three-dimensional ultrasound image using the acquired two-dimensional image data while mechanically scanning with the transducer array in a direction substantially orthogonal to the array direction of the transducer array; and a controller which, when the internal temperature of the ultrasound probe is equal to or higher than a first set value, controls the transmission and reception circuit such that a composite scan including two different electronic scans is performed.

  • Patent number: 8641627
    Abstract: Transesophageal echocardiography is implemented using a miniature transversely oriented transducer that is preferably small enough to fit in a 7.5 mm diameter probe, and most preferably small enough to fit in a 5 mm diameter probe. Signal processing techniques improve the depth of penetration to the point where the complete trans-gastric short axis view of the left ventricle can be obtained, despite the fact that the transducer is so small. The reduced diameter of the probe (as compared to prior art probes) reduces risks to patients, reduces or eliminates the need for anesthesia, and permits long term direct-visualization monitoring of patients' cardiac function.

  • Publication number: 20140031692
    Abstract: According to an ultrasonic probe using a vertically arranged motor, a motor stands upright in the ultrasonic probe and a side pulley is located in a tangential direction of a probe-shaft pulley, thereby enabling a rotating force generated by the vertically arranged motor to be smoothly transferred to an array axis of ultrasonic elements and significantly simplifying a structure of the ultrasonic probe to remarkably reduce manufacturing costs. In addition, according to the ultrasonic probe using the vertically arranged motor, a mechanism which enables a linear operation is implemented while using the vertically arranged motor. Thus, the ultrasonic probe may have an ergonomic design to significantly improve user satisfaction.

  • Publication number: 20130338505
    Abstract: An intra-operative ultrasound probe for use with a robotic and laparoscopic surgical systems that allows for direct surgeon control over the position and orientation of the ultrasound image is presented. The transducer is designed to interface with the laparoscopic grasper so that it is easy to pick up in a locking, self-aligning and repeatable manner. The transducer is tracked in space using either forward kinematics or electromagnetic sensing, allowing multiple 2D images to be combined in order to create 3D ultrasound volumes. The 3D volumes can be further processed and displayed on the surgeon's console, or used to register and display acquired pre-operative images at the correct spatial location within the patient.
