The ultrasound diagnosis apparatus includes a storage, an identification unit, and a controller. The storage stores association information in which operation instructions are each associated with a finger type. The identification unit identifies the finger type of a finger that has touched any position on the touch panel. The controller performs one of the operation instructions associated with the finger type identified based on the association information.Type: ApplicationFiled: January 25, 2018Publication date: July 26, 2018Applicant: Canon Medical Systems CorporationInventors: Takeshi SUGIO, Tomio Nabatame, Takashi Masuda, Asuka Ozawa

Publication number: 20180206823Abstract: To increase the signal-to-noise ratio for displacements used to estimate the shear speed in patient tissue, constructive interference from multiple shear waves is used. By transmitting acoustic radiation force impulses focused at different locations, the resulting shear waves may constructively interfere within a region of interest. This constructive interference causes a greater amplitude of displacement. The location of this more easily detected greater interference and the difference in time of the transmitted acoustic radiation force impulses are used to estimate the shear wave speed for the tissue.Type: ApplicationFiled: January 23, 2017Publication date: July 26, 2018Inventors: Yassin Labyed, Liexiang Fan

Publication number: 20180206824Abstract: An ultrasound diagnostic apparatus includes the following. An ultrasound probe includes a transmitting opening including a plurality of transducers, and the transmitting opening includes a plurality of transducer groups including at least a first transducer group and a second transducer group. A transmitter generates a plurality of driving signals with different driving waveforms including at least a first driving signal and a second driving signal, provides a time delay to the plurality of driving signals so that the transmitting ultrasound focuses to a same focal point, outputs the first driving signal to the first transducer group, outputs the second driving signal to the second transducer group, and outputs the plurality of driving signals to the plurality of transducer groups of the transmitting opening. A receiver receives the receiving signal from the ultrasound probe. An image generator generates the ultrasound image data from the receiving signal.Type: ApplicationFiled: January 18, 2018Publication date: July 26, 2018Inventor: Tetsuya TANIGUCHI

Publication number: 20180206825Abstract: Methods and systems for ultrasound data processing are provided. One method includes acquiring channel ultrasound data from a plurality of channel connected to a plurality of elements of an ultrasound probe and storing the channel ultrasound data from the plurality of channels. The method further includes generating ultrasound images based on processing of the acquired channel ultrasound data and displaying the ultrasound images. The method also includes performing additional processing on the stored channel ultrasound data while the ultrasound images are displayed and displaying updated ultrasound images generated by the additional processing.Type: ApplicationFiled: March 7, 2018Publication date: July 26, 2018Inventors: Morris Ziv-Ari, Arcady Kempinski, Alexander Sokulin

Publication number: 20180206826Abstract: Combined transducer arrays for imaging features of tissue include a transducer array configured for transmit-receive ultrasound imaging, and a transducer array configured for receive-only thermoacoustic imaging. The transmit-receive transducer array includes a plurality of transmit-receive array elements, and the receive-only transducer array includes a plurality of receive-only array elements. The receive-only array elements are registered with and surround the transmit-receive array elements. The receive-only transducer array and transmit-receive transducer array may be housed in an ultrasound probe. The combined transducer arrays may be used in composite imaging of tissue, based on the registration of the transmit-receive array elements and the receive-only array elements.Type: ApplicationFiled: May 14, 2015Publication date: July 26, 2018Applicant: ENDRA, INC.Inventors: Michael M. THORNTON, Paul A. PICOT

Publication number: 20180206827Abstract: An ultrasonic diagnostic system includes elements disposed around a subject to transmit and/or receive ultrasonic waves. A controller controls the elements so that some of the elements disposed in a first region transmit ultrasonic waves at a first angle to a diagnosis target in the subject, some of the elements disposed in a second region receive reflected waves of the ultrasonic waves, which are reflected from the diagnosis target at a second angle, and some of the elements disposed in a third region receive reflected waves of the ultrasonic waves, which are reflected from the diagnosis target at a third angle distinct from the second angle. An operator calculates a velocity vector of the diagnosis target using the reflected waves received by the some of the elements disposed in the second region and the reflected waves received by the some of the elements disposed in the third region.Type: ApplicationFiled: March 23, 2018Publication date: July 26, 2018Inventors: Takashi Azuma, Hirofumi NAKAMURA

Publication number: 20180206828Abstract: An exemplary ultrasound biopsy device includes a probe and a holster. The probe is insertable into the holster to form a completed assembly. To assemble the probe to the holster, the probe is initially slid laterally onto the holster and then slid forward to latch the probe into engagement with the holster. The holster is coupled to a vacuum control module by one or more conduits and a power cable. The conduits and/or power cable may be retracted into the vacuum control module. The probe of the biopsy device includes a blade assembly at the distal end. The blade assembly comprises a blade that snaps onto a nosecone via a pair of resilient notched ends. A frictional fitting needle cover can be inserted over the needle and blade assembly to protect the user from the sharp blade.Type: ApplicationFiled: March 21, 2018Publication date: July 26, 2018Inventors: Kevin M. Fiebig, John A. Hibner, Edward A. Rhad, John S. Ehlert, Morgan R. Hunter

Publication number: 20180206829Abstract: Methods and devices for providing a biopsy device with a modified handle and stylet that provides a vacuum to be delivered to the targeted tissue for removal. The vacuum may draw the tissue into the notch where the tissue may then be severed via the cannula. Alternatively, the tissue may be drawn into to the notch after being severed via the stylet and/or cannula. The vacuum may be used to bring a larger amount of tissue into the notch than would otherwise be brought in the notch if no vacuum was used, providing a larger sample through the same size access point.Type: ApplicationFiled: January 31, 2018Publication date: July 26, 2018Inventors: Michael Plishka, Evan Linderman, John A.
