    Abstract: The invention relates to an imaging system for imaging a periodically moving object. An assigning unit (18) assigns ultrasound signals like A-lines to motion phases based on a provided phase signal,wherein an ultrasound images generation unit (19) generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. The ultrasound images are temporally consecutively displayed on a display unit (21) for showing the periodic movement of the object (24).The resulting dynamic, movie-like image of the object allows a user like a physician to more reliably determine properties of the object like a thickness of a tissue wall, in particular, during an ablation procedure. The imaging system is therefore particularly useful for monitoring cardiac ablation procedures.

An assigning unit (18) assigns ultrasound signals like A-lines to motion phases based on a provided phase signal, wherein an ultrasound images generation unit (19) generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. A selecting unit (20) is used to select an ultrasound image from the generated ultrasound images, wherein a display unit (21) displays the selected ultrasound image. The selected ultrasound image corresponds therefore to a single motion phase only such that motion artifacts in the displayed ultrasound image are reduced. The imaging system is particularly useful for, for instance, monitoring cardiac ablation procedures.

    Abstract: Disclosed is an ultrasound image processing apparatus (5) comprising an image processor arrangement (50) adapted to receive a first sequence (100') of ultrasound images (150) imaging an anatomical feature of interest (151) during a first full cardiac cycle in the absence of an invasive medical device (15) in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle; receive a further sequence (100') of ultrasound images (150) imaging the anatomical feature of interest (151) during a further full cardiac cycle in the presence of the invasive medical device (15) in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle said invasive medical device (15) at least partially obscuring the anatomical feature of interest, and for each ultrasound image of the further sequence: track the location of the invasive medical device in the ultrasound image; isolate the invasive medical device from the ultrasound image; and insert the isolated invasive medical device into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location; and control a display device to display the first sequence of ultrasound images including the inserted invasive medical device. Also disclosed are an ultrasound imaging system comprising such an ultrasound image processing apparatus and a computer program product facilitating the configuration of such an image processing apparatus in accordance with embodiments of the present invention.

    Abstract: Images may be preprocessed to select pixels or voxels of interest prior to being analyzed by a neural network. Only the pixels or voxels of interest may be analyzed by the neural network to identify an object of interest. One or more slices may be extracted from the voxels of interest and provided to the neural network for analysis. The object may be further localized after identification by the neural network. The preprocessing, analysis by the neural network, and/or localization may utilize pre-existing knowledge of the object to be identified.

    Abstract: The invention provides an ultrasound system including an ultrasound transducer array and a processor. The ultrasound transducer array comprises a plurality of transducer elements adapted to conform with a subject's body. Further, at least two ultrasound transducer elements of the plurality of transducer elements are adapted to acquire a plurality of ultrasound signals from a region of interest at different orientations relative to said region of interest. The processor is adapted to receive ultrasound signals acquired by the ultrasound transducer array. The processor is further adapted to partition the plurality of ultrasound signals according to a signal depth and, for each ultrasound signal partition, calculate a Doppler power. For each ultrasound signal, the processor identifies a depth of a fetal heartbeat based on the Doppler power of each ultrasound signal partition and identifies a fetal heart region based on the identified fetal heartbeat and a location of the at least two ultrasound transducers.
