The systems can be configured to display ultrasound images on a display device and receive input to select the ultrasound images for which to retrieve corresponding raw ultrasound data from the ultrasound machine. A raw data buffer provided at the ultrasound machine may be capable of storing a first time duration of raw ultrasound data. An image display buffer provided at the wireless device may store: processed ultrasound image data corresponding to the raw ultrasound data stored in the raw data buffer; and previously-received processed ultrasound image data that has no corresponding raw ultrasound data stored in the raw data buffer.

An ultrasonic probe includes: a piezoelectric element that is used for transmitting and receiving ultrasonic waves; a signal electrode that is disposed at a rear surface side of the piezoelectric element; and a backing that is disposed at a rear surface side of the signal electrode, wherein the backing has a thermal resistance of 8 K/W or less, and the backing attenuates an ultrasonic wave with the lowest frequency by 10 dB or more, among frequencies at which transmittance and reception sensitivity of the ultrasonic probe is decreased from the maximum value thereof by 20 dB.

An electronic system for a surgical instrument is disclosed. The electronic system comprises a main power supply circuit configured to supply electrical power to a primary circuit. A supplementary power supply circuit configured to supply electrical power to a secondary circuit. A short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. The supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit. The supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.

The invention relates to a method for generating a synthetic elastography image (18), the method comprising the steps of (a) receiving a B-mode ultrasound image (5) of a region of interest; (b) generating a synthetic elastography image (18) of the region of interest by applying a trained artificial neural network (16) to the B-mode ultrasound image (5). The invention also relates to a method for training an artificial neural network (16)5 useful in generating synthetic elastography images, and a related computer program and system.

Provided is an ultrasound imaging device and an operation method thereof. An embodiment of the present disclosure provides an ultrasound imaging device comprising: an ultrasound probe; a display unit; a memory for storing at least one instruction; and a processor for executing the at least one instruction stored in the memory, wherein the processor: image-processes an echo signal to acquire multiple ultrasound images; calculates suitability indicating, as a numerical value, whether the multiple acquired ultrasound images are suitable as input images for a diagnosis algorithm for diagnosing a lesion; displays the calculated suitability on the display unit; and determines an input ultrasound image, which is to be input into the diagnosis algorithm, among the multiple ultrasound images based on the suitability.

There are provided an acoustic wave image generating apparatus for generating a B-mode image having a fixed brightness and a control method thereof. First brightness information (81) indicating the brightness of a first B-mode image in the depth direction of the subject is generated. Positional deviation correction is performed on an acoustic wave echo signal having a positional deviation between the focusing position of acoustic waves and the observation target position, and second brightness information (82) indicating the brightness in the depth direction of the subject is generated from a superposition signal obtained by superimposing an acoustic wave echo signal for which the positional deviation has been corrected and an acoustic wave echo signal without positional deviation. The brightness of the first B-mode image is corrected based on the first brightness information and the second brightness information.

A system and method for performing a non-fluoroscopic transseptal procedure may comprise a catheter and a device comprising a sheath, an introducer and a transducer embedded on the introducer and configured to perform a measurement during the non-fluoroscopic transseptal procedure. In this system, the transducer may be embedded on the outer surface of the introducer, or embedded on the inner surface of the introducer, or embedded within the introducer. The transducer may be a ring transducer or a circular transducer. The measurement is based on a plurality of ultrasonic pulses transmitted from the transducer, and the measurement determines a location of the catheter and/or a puncture location. In another embodiment, the transducer is embedded on a needle instead of an introducer.

A device comprises a miniature transducer having an altered backing geometry that can be placed within different casing sizes of an imaging probe device. The backing geometry extends along a longitudinal axis of the imaging probe and provides an angle (e.g., 45-degree angle) configured to reflect ultrasound and/or light waves/signals in a direction perpendicular to the longitudinal axis of the imaging probe. This design is configured to enable ultrasound and/or light waves/signals to be redirected and dampened within the transducer to preserve a suitable signal to noise ratio while minimizing the required depth of the backing.
