A method for locating and visualizing a target (C) in relation to a focal point (F2), in a mammal, particularly a human body, including the steps of forming an ultrasound probe mobile in space, mechanically independent of a treatment system and located by a remote locating system, ensuring the simultaneous recording firstly of an ultrasound image in which the image of the target appears, and secondly of the position of the ultrasound probe, in the recorded ultrasound image, selecting the position of the image of the target to determine the virtual position of the target (C), simultaneously determining firstly the position of the focal point (F2) by means of the remote locating system, and secondly the position of the means displacing the target and/or treatment system, and calculating the displacement values for the displacing means, to cause the virtual position of the target (C) to coincide with the focal point (F2).

The invention discloses an ultrasonic image video classification prediction method and system. The invention relates to the field of image processing, in particular to a video classification method, which comprises the steps of acquiring an original video image containing time dimension, image width and image height, extracting features of the original video image by using a feature extraction network, and performing time sequence up-sampling on the features to output a classification prediction result which comprises a standard tangent plane and a non-standard tangent plane. Time sequence information of an original video image is efficiently learned by using a feature extraction network, and a classification prediction result of each frame of a video clip is output through time sequence up-sampling, so that the prediction efficiency is improved, and when the method is used for ultrasonic video data, the ultrasonic diagnosis efficiency can be improved, the burden of doctors is reduced,and the problem of insufficient medical resources is solved. The method can be widely applied to the video image prediction field.

A portable ultrasound scanning system comprising a hand-held housing, ultrasound electronics of a complete ultrasound scanning system, including a beamformer and an image processing unit, contained within the hand-held housing. A first display comprises a touchscreen on the hand-held housing with a user input interface, at least partially presented on the first display. A probe containing a plurality of piezoelectric transducers is controlled by the ultrasound electronics and is connected to the housing via a cable. The ultrasound electronics are configured to receive signals from the probe and to convert those signals and provide converted signals to the first display to display a scanned ultrasound image on the first display. A second, larger, display is located remote from the housing. A connection arrangement is configured to selectively connect the second display to the ultrasound electronics, and automatically upon such connection, display the scanned image on the second display.

The invention relates to an ultrasound diagnosis apparatus and an image-information management apparatus. According to one embodiment, the ultrasound diagnosis apparatus includes an image memory, an output-information creating unit, and a control unit. The image memory associates and stores an ultrasound image and a first image that is set in accordance with a schematic image representing a portion imaged onto the ultrasound image and a positional image indicating a scanning position with ultrasound when creating the ultrasound image. The output-information creating unit creates a second image based on a shape of the first image stored by the image memory. The output-information creating unit then creates an image that image information extracted from the ultrasound image associated with the first image is superimposed onto the created second image, as output information. The control unit performs control of outputting the output information created by the output-information creating unit to an external device.

An ultrasound diagnostic apparatus includes a determining unit adapted to determine a depth position of a boundary of the intima-media complex at the clear boundary sound ray, and ascertain a depth position of the boundary of the intima-media complex at the unclear boundary sound ray; and an calculator adapted to calculate an intima-media complex thickness based on the depth positions of the boundary of the intima-media complex, wherein the determining unit performs pattern matching on a sound ray signal corresponding to the unclear boundary sound ray by using a sound ray signal corresponding to a clear boundary sound ray lying adjacent to the unclear boundary sound ray as a reference signal, thereby ascertaining the depth position of the boundary of the intima-media complex at the unclear boundary sound ray.

The invention discloses a denoising method for a human embryo heart ultrasonic image based on a deep convolutional neural network, and the method comprises the following steps: obtaining an ultrasonicimage data set with time sequence and space sequence features, selecting a central image, and determining an adjacent image of the central image; calculating the similarity between the central pixelof the central image and each pixel in the search domain corresponding to the adjacent image; calculating a central pixel gray value corresponding to the adjacent image according to the similarity information and averaging the central pixel gray value to obtain a final gray value of the central pixel; and constructing a deep convolutional neural network model, and inputting the ultrasonic image which is not denoised into the trained deep convolutional neural network model to carry out denoising processing to obtain a difference between the noise image and the clean image, namely a residual image.
