There is provided an ultrasonic signal processing apparatus in which the amount of an ultrasonic propagation material in a measurement unit that stores a transducer array is reduced while the transducer array and a target are separated from each other, and thus maintenance of the ultrasonic propagation material is easily managed.

The ultrasonic signal processing apparatus includes a water tank having an opening portion, a measurement unit, and a moving unit. The measurement unit which is disposed on an outside of the water tank, includes a transducer array that transmits and receives an ultrasonic signal, and a space which is filled with a material for propagating the ultrasonic signal, and measures the ultrasonic signal. The moving unit is connected to the measurement unit, and moves the measurement unit between the opening portion and the bottom portion of the water tank, along a side wall thereof.

A testing system for testing a work piece. The testing system may be non-destructive. An associated method. The method may include obtaining C-scan images and corresponding S-scan images. The C-scan images and the corresponding S-scan images are of the same portion of the work piece being tested.

High-speed three-dimensional reconstruction of elasticity data is obtained by acquiring a sparse set of data in planes sharing a common axis line and angularly arrayed about the axis line. The axis line may be an RF ablation probe and the reconstruction may enforce a circumferential smoothness in the reconstruction about the probe, as is compatible with an ablation volume.

An ultrasound system including: a housing including a handle region and a membrane; an ultrasound transducer; a reservoir; a rotational actuator; and an electronics module.

Devices, systems, and methods for controlling an intravascular imaging device are provided. For example, in one embodiment a method includes communicating a control signal to an actuator of the intravascular imaging device to cause oscillation of an imaging element of the intravascular imaging device, wherein the intravascular imaging device further includes an acoustic marker; receiving imaging data from the imaging element of the intravascular imaging device; identifying the acoustic marker in the imaging data by determining a correlation between the imaging data and a template representative of the acoustic marker; adjusting an aspect of the control signal based on identifying the acoustic marker; and communicating the adjusted control signal to the actuator of the intravascular imaging device.

A non-destructive testing system for testing a work piece. The non-destructive testing system includes an ultrasonic probe, including a matrix of transducers, and a control unit including a display. The control unit is configured to control the ultrasonic probe. The ultrasonic probe and the control unit are configured to obtain multiple S-scan images. The ultrasonic probe and the control unit are configured to obtain a first S-scan image at a first direction orientation, and the ultrasonic probe and the control unit are configured to obtain a second S-scan image at a second direction orientation different from the first direction orientation. The control unit is configured to process the first and second S-scan images to provide at least an image upon the display.

An ultrasonic probe includes a transmitting unit including a transmitting surface that transmits ultrasonic waves, a receiving unit including a receiving surface that receives the ultrasonic waves, and a receiving attitude changing unit that changes an angle of the receiving unit, wherein a part of the transmitting unit includes a second receiving unit (group of transmitting and receiving transducers) that can receive the ultrasonic waves.

Disclosed herein is an ultrasonic diagnostic apparatus which includes a probe including a transducer installed to be rotatable, a driving device configured to rotate the transducer, at least one wire configured to transmit power of the driving device to the transducer, a handle case configured to accommodate the driving device therein, a cap coupled to the handle case to accommodate the transducer therein, and filled with oil, and a diaphragm formed of a deformable material and disposed between the cap and the handle case, wherein the wire is installed to pass through the diaphragm, and fixed to the diaphragm so that the diaphragm is deformed according to movement of the wire. Since the wire is fixedly installed to pass through the diaphragm and deformed according movement of the wire, oil in the cap is prevented from leaking to the handle case.

There are disclosed embodiments of devices and methods for imaging the inside of a body part, particularly a blood vessel. In particular embodiments, a catheter has a tip chamber, within which is an ultrasound transducer mounted on a pivot mechanism, a motor for turning the transducer, and an implement for pivoting the transducer. Examples of such an implement are a linear motor, a shaft or filament, and the pivot mechanism may be biased to return to a base position when the implement is not pivoting the transducer. In other embodiments, a mirror reflecting ultrasound signals from the transducer may be rotated and/or pivoted, using similar mechanisms.

Methods and systems for acquiring a plurality of data vectors at a first frequency and a plurality of data vectors at a second frequency, where the first frequency is greater than the second frequency. The plurality of first frequency data vectors can be formed into a first set of data vectors and the plurality of second frequency data vectors can be formed into a second set of data vectors. A first filter can be applied to the first set of data vectors to form a first modified data set and a second filter can be applied to the second set of data vectors to form a second modified data set. Based on the first and second modified data sets, a frequency response of an item in the imaging view can be determined. Using the determined frequency response of the item, an image is created on a display.
