The present invention relates to the field of medical ultrasound imaging, and in particular to a medical ultrasound image processing device for supporting reproducible acquisition of 2D ultrasound images. A medical ultrasound image processing device (10) is presented that comprises a first interface (2) for receiving a first 3D scout ultrasound image (3) and a first 2D ultrasound image (4) of a volumetric region; a second interface (5) for receiving a second 3D scout ultrasound image (6) of the volumetric region; and a processing unit (11) arranged to perform the steps of: determining an orientation of an image plane of the first 2D ultrasound image with respect to the first 3D scout ultrasound image (S73); registration of the first 3D scout ultrasound image and the second 3D ultrasound scout image in a common coordinate frame (S75); determining an orientation of the image plane of the first 2D ultrasound image with respect to said common coordinate frame based on said registration of the first and second 3D scout ultrasound images and the determined orientation of the image plane of the first 2D ultrasound image with respect to the first 3D scout ultrasound image (S76); and providing a control signal adapted to control an acquisition of a second 2D ultrasound image of the volumetric region by an ultrasound probe in accordance with the orientation of the image plane of the first 2D ultrasound image of the volumetric region (S77), wherein an orientation of an image plane of the second 2D ultrasound image corresponds to the determined orientation of the image plane of the first 2D ultrasound image of the volumetric region, wherein the acquisition of the second 2D ultrasound image by the ultrasound probe is from either a same position as, or a tracked position with respect to, the position of the acquisition of the second 3D scout ultrasound image.

The invention relates to determining a fetal heart rate from an ultrasonic Doppler echo signal. Rather than extracting the Doppler signal from the carrier signal using synchronous demodulation, quadrature demodulation is used, which allows to distinguish between systolic and diastolic movements. This velocity direction can be used to cut out unwanted parts of the signal (systolic or diastolic heart activity), thus eliminating double counting heart rates. In particular, a binary sign signal (15′) may be used to cut out unwanted signal episodes, resulting in a processed reference signal (10′) having only the signal parts of one heart activity. Another aspect relates to determining a first and a second heart rate from at least two channels having a different depth range, and selecting one of the first and second heart rate based on external information of the fetal or maternal heart rate.

The present disclosure describes imaging systems configured to generate index information to indicate which image frames in a plurality of image frames include one or more target anatomical features, such as a head or femur of a fetus. The confidence levels of the presence of the target anatomical features are also determined. The system may be configured to determine if the target anatomical feature is present in an image frame by implementing at least one neural network. Merit levels based on the quality of the image frames may also be determined. Measurements of the one or more items of interest may be acquired. Visual representations (500) of the index information (502), confidence levels, merit levels, and/or measurements may be provided via a user interface. A user interface may receive user inputs based on the visual representations to navigate to specific image frames (508) of the plurality of image frames.

Systems and methods of predicting future medical events are based on the processing of medical image. The prediction of premature birth and estimation of gestational age based on ultrasound images are presented as illustrative examples. The new abilities to estimate the probability of future medical events, before they otherwise could be predicted, provides new avenues for the development of preventative treatments.

A system and method for adapting user interface elements based on real-time anatomical structure recognition in acquired ultrasound image views is provided. The method includes acquiring, by an ultrasound system, an ultrasound image view. The method includes automatically detecting, by at least one processor of the ultrasound system, a target view from a set of target views. The target view corresponds with the ultrasound image view. The method includes automatically determining, by the at least one processor, one or both of a presence or absence of a plurality of anatomical features associated with the target view in the ultrasound image view. The method includes presenting, by the at least one processor, at least one user interface element indicating the one or both of the presence or absence of each of the plurality of anatomical features at a display system.

A system for determining a volume of breastmilk ingested by a baby, e.g., an infant, during a breastfeeding session includes an ultrasound source configured to transmit ultrasonic waves to a stomach of the baby; an ultrasound sensor configured to receive ultrasonic echoes generated by reflection of the ultrasonic waves from the stomach; and a processor configured to detect a boundary of the stomach and a level of a liquid surface within the stomach based on the received ultrasonic echoes, and determine a volume ingested into the stomach during the breastfeeding session based on the detected boundary of the stomach and the detected level of the liquid surface. Ultrasound measurements during a breastfeeding session are not affected by natural processes such as swallowing air, voiding during feedings, and spitting up, providing increased confidence to breastfeeding mothers. These measurements are also obtained non-invasively, providing minimal if any distraction to the feeding child.

A system and method for enhancing color flow Doppler and pulsed wave Doppler ultrasound images acquired based on clinically-specific profiles of imaging parameters is provided. The method includes presenting selectable clinical objects at a display. Each of the selectable clinical objects may be associated with color flow Doppler and pulsed wave Doppler profiles. Each of the profiles may comprise imaging parameters for the associated clinical object. The method includes receiving a selection of one of the selectable clinical objects and retrieving the color flow Doppler and pulsed wave Doppler profiles associated with the selected clinical object.

Aspects of the technology described herein relate to enhancing ultrasound data. Some embodiments include receiving ultrasound data and automatically determining, with a processing device, that the ultrasound data depicts an anatomical view or one of a set of anatomical views. Based on automatically determining that the ultrasound data depicts the anatomical view or one of the set of anatomical views, an option is enabled to perform ultrasound data enhancement specific to the anatomical view or the set of anatomical views. Based on receiving the selection of the option, the ultrasound data, a portion thereof, and/or subsequently-collected ultrasound data is enhanced using the ultrasound data enhancement specific to the anatomical view or the set of anatomical views.
