摘要： Provided in the present application are an ultrasonic imaging system, a non-transitory computer-readable medium, and an ultrasonic imaging method. The method includes generating an ultrasound image and displaying it on a display device. The method includes receiving a gesture instruction from a user, the gesture instruction being generated by a sliding operation on a touch screen. The method includes performing identification of the gesture instruction; and, in response to the gesture instruction being identified, generating a feedback signal so as to provide identification feedback to the user, and controlling an ultrasonic imaging system to enter an operating mode corresponding to the gesture instruction.

摘要： A medical device is described. The medical device includes a table and a processor. The processor executes operations including, driving the table based on an offset for correcting the table height positional offset to position the imaging location of a subject at a prescribed table height position, determining a center of gravity of the imaging location of the subject in the height direction of the table based on the medical image of the imaging location of the subject, calculating a difference between the prescribed position and the center of gravity as positional deviation of table height, and storing the positional deviation. The processor further executes operations including obtaining a representative value representing characteristics of the positional deviation distribution, determining whether the representative value of the positional deviation is statistically reliable, and updating the offset based on the representative value if the representative value is determined to be statistically reliable.

摘要： Image reconstruction systems and methods include providing sensitivity maps for coils of a magnetic resonance imaging (MRI) system to a neural network. The systems and methods also include providing interleaved k-space data to the neural network, wherein the interleaved k-space data includes partial k-space data interleaved with zeros, or synthesized k-space data, to provide an extended field of view (FOV) different from a FOV utilized during acquisition of the partial k-space data, wherein the partial k-space data were obtained during a scan of a region of interest with the MRI system. The systems and methods further include outputting, from the neural network, a final reconstructed MR image based at least on the sensitivity maps and the interleaved k-space data, wherein the final reconstructed MR image includes the FOV utilized during the acquisition of the partial k-space data.

摘要： Methods and systems are provided for training machine learning models to filter medical images with a reduced incidence of filtering artifact inclusion. In one example, training data may be generated by applying a filter to a medical image to produce a filtered medical image, wherein a subregion of the filtered medical image includes a filtering artifact, displaying the filtered medical image via a display device, receiving a selection of the subregion of the filtered medical image from a user input device, blending, in the subregion, pixel intensity values from the filtered medical image with pixel intensity values from the medical image, to produce a blended image, wherein a visibility of the filtering artifact is attenuated in the blended image, and displaying the blended image via the display device.
