Abstract: An ultrasound imaging system for needle insertion guidance uses a curved array transducer to scan an image field with unsteered beams as a needle is inserted into the image field. Due to differences in the angle of incidence between the radially directed beams and the needle, echoes will return most strongly from only a section of the needle. This section is identified in an image, and the angle of incidence producing the strongest returns is identified. Beams with this optimal angle of incidence are then steered in parallel from the curved array transducer to produce the best needle image. The steep steering angles of some of the steered beams can give rise to side lobe clutter artifacts, which can be identified and removed from the image data using dual apodization processing of the image data.

Abstract: An ultrasound imaging system includes an array of acoustic elements and a processor circuit configured for communication with the array of acoustic elements. The processor circuit may be configured to control the array of acoustic elements to transmit first ultrasound energy at a first frequency and receive echoes associated with the first ultrasound energy. The processor circuit may be configured to identify an acoustic window based on the echoes associated with the first ultrasound energy and determine a second frequency based on the acoustic window. The processor circuit may be configured to control the array of acoustic elements to transmit second ultrasound energy at the second frequency and receive echoes associated with the second ultrasound energy. The processor circuit may be configured to generate an image based on the echoes associated with the second ultrasound energy and to output the image to a display in communication with the processor circuit.

Abstract: Disclosed is an ultrasound imaging system that includes a remote server configured for communication with a first ultrasound imaging console and a second ultrasound imaging console. The server is configured to receive, from the first ultrasound imaging console, an upload request for a custom image setting, receive and store the custom image setting. The server is further configured to output, to the second ultrasound imaging console, data representative of the custom image setting; receive a request for the custom image setting; retrieve and send, to the second ultrasound imaging console, the custom image setting such that the second ultrasound imaging console can generate an image with the custom image setting.

Abstract: An artificial insemination device for private use which is capable of allowing unskilled persons to achieve an artificial insemination of livestock such as cattle, horses, and deer, etc. in a simple and easy manner using frozen semen of those livestock. The device includes an in-vagina insert unit inserted into the vagina of a female to be inseminated upon injecting semen into the female, and a semen injection unit inserted into the womb canal of the female through the in-vagina insert unit upon injecting semen into the female. The in-vagina insert unit includes a hollow insert body, and an insert tube slidably fitted at its rear end in a front end of the insert body in such a manner that its length protruded from the insert body is adjustable in accordance with the depth of the vagina of the female. The semen injection unit includes an elongated semen injection tube connected at a rear end thereof to an injector, and a guide/nozzle member separably coupled to a front end of the semen injection tube.
