A processor of a general-purpose terminal acquires position information indicating whether a biological body is punctured from a first side of an ultrasonic probe apparatus or a second side opposite to the first side and angle information indicating a puncture angle, where these items of information are entered on a touch panel of a display, transmits these items of information to the probe apparatus via a wireless communication circuit, acquires, via the communication circuit, image information generated and transmitted by the probe apparatus based on reflected waves obtained by transmitting ultrasonic waves into the biological body from the probe apparatus at a first angle based on the above information, superimposes a puncture guide indicating a puncture path based on the above information on an ultrasonic image of the biological body or a puncture needle based on the image information, and displays a result of the superimposing on the display.

An ultrasonic diagnostic apparatus, including a transceiver for sequentially generating multiple received signals, a color flow mapping signal processing unit that generates blood flow velocity data based on the multiple received signals, and a residual image processing unit that includes an aliasing determination unit and a persistence calculation unit and performs residual image processing on blood flow velocity data, an aliasing determination unit that adds the blood flow velocity data V.sub.current for the most recent frame and the blood flow velocity data V.sub.out-1 for the frame preceding the most recent frame, performs aliasing determination on the frame that was determined by a frame before the most recent frame based on the aliasing determination results of the blood flow velocity data, and a persistence calculation unit that performs a persistence calculation after performing a correction to the blood flow velocity data in which aliasing has occurred.

Provided is a technique that implements harmonic imaging in an ultrasound diagnostic apparatus, being unaffected by the voltage-dependent distortion and nonlinear characteristics of the transmit system in the ultrasound diagnostic apparatus that incorporates the transmit amplifier, the ultrasound probe, and the like, facilitating adjustment of the transmit voltage, and achieving a frame rate substantially equivalent to that of the conventional PI method. In the amplitude modulation method that synthesizes the transmit acoustic fields, thereby eliminating a basic wave component of an acoustic wave and creating an image from nonlinear component echoes being extracted, one transmit and receive out of plural transmits and receptions to obtain one scanning line also serves as the transmit and receive for obtaining other scanning line. The echo signals obtained by the shared transmit and receive are used to form the receive beams respectively on both the scanning lines that share the transmit and receive.

Data is communicated from an implanted section to an external location. The implanted section includes a transducer such as a piezoelectric element with an ultrasound reflecting surface that moves in response to an applied driving signal. A sensor generates an output signal that depends on a sensed parameter, and a control circuit drives the transducer based on the sensor's output. The transducer's response to the driving signal is repeatable such that the value of the output signal can be determined by measuring the variations in the velocity of the surface using externally applied Doppler ultrasound, and computing the value of the sensor's output from the measured variations in velocity.

A long-term implantable ultrasound therapy system and method is provided that provides directional, focused ultrasound to localized regions of tissue within body joints, such as spinal joints. An ultrasound emitter or transducer is delivered to a location within the body associated with the joint and heats the target region of tissue associated with the joint from the location. Such locations for ultrasound transducer placement may include for example in or around the intervertebral discs, or the bony structures such as vertebral bodies or posterior vertebral elements such as facet joints.

An apparatus may include an ultrasonic receiver array, an ultrasonic transmitter and a control system capable of controlling the ultrasonic transmitter to transmit first ultrasonic waves in a first direction and to simultaneously transmit second ultrasonic waves in a second direction that is opposite the first direction. The control system may be capable of distinguishing first reflected waves from second reflected waves, the first reflected waves corresponding to reflections of the first ultrasonic waves that are received by the ultrasonic receiver array and the second reflected waves corresponding to reflections of the second ultrasonic waves that are received by the ultrasonic receiver array. The control system may be capable of determining first image data corresponding to the first reflected waves and of determining second image data corresponding to the second reflected waves.

A system for sensing a position of an ultrasound imaging device includes an ultrasound (US) imaging device, and a position sensor mount, and a position sensor. The position sensor mount includes an elastic body portion, a first rigid shell disposed on a distal portion of the elastic body portion, a second rigid shell disposed on a proximal portion of the elastic body portion, and a first adhesive disposed on the first rigid shell. The position sensor is mounted on the first rigid shell and configured to sense position information of the US imaging device in a coordinate system.

An ultrasound imaging system comprising a multi-use electronic display device and an ultrasound imaging device. The multi-use electronic display device is capable of communicating with one or more ultrasound imaging devices and selecting which to connect with based on at least one of previously store information, user input, and information gathered from the ultrasound imaging devices. The multi-use electronic display device may communicate with the ultrasound imaging devices while they are in a low power standby state. This approach reduces the complexity of the pairing process and provides a means for quickly and easily selecting between multiple ultrasound imaging devices.

Utilization of a contact device placed on the eye in order to detect physical and chemical parameters of the body as well as the non-invasive delivery of compounds according to these physical and chemical parameters, with signals being transmitted continuously as electromagnetic waves, radio waves, infrared and the like. One of the parameters to be detected includes non-invasive blood analysis utilizing chemical changes and chemical products that are found in the conjunctiva and in the tear film. A transensor mounted in the contact device laying on the cornea or the surface of the eye is capable of evaluating and measuring physical and chemical parameters in the eye including non-invasive blood analysis. The system utilizes eye lid motion and/or closure of the eye lid to activate a microminiature radio frequency sensitive transensor mounted in the contact device. The signal can be communicated by wires or radio telemetered to an externally placed receiver. The signal can then be processed, analyzed and stored. Several parameters can be detected including a complete non-invasive analysis of blood components, measurement of systemic and ocular blood flow, measurement of heart rate and respiratory rate, tracking operations, detection of ovulation, detection of radiation and drug effects, diagnosis of ocular and systemic disorders and the like.
