    Abstract: A system (10) is for performing ECG measurements and comprises a probe (12) with an integrated one or more ECG electrodes (22) and an ultrasound sensing means (18), such as a transducer arrangement. The probe thus provides a mobile ECG electrode which can be sequentially moved between a set of different locations on the body for acquiring ECG measurements from different angles relative to the heart (i.e. different 'leads'). Positioning of the probe in each required location is guided by a position guidance function which uses ultrasound data acquired by the ultrasound sensing means to locate the probe (with reference to an ultrasound body atlas (28) or map), and uses a stored set of reference body locations to guide a user with guidance information as to how to move the probe to arrive at a next target electrode location. In examples, the user may be guided through a sequence of electrode locations, with ECG data acquired at each one, thereby sequentially building up a set of standard ECG lead measurements.

    Abstract: Disclosed is an ultrasound image processing apparatus (5) comprising an image processor arrangement (50) adapted to receive a plurality of ultrasound images (150), each ultrasound image imaging an invasive medical device (15) relative to an anatomical feature of interest (151) during a particular phase of a cardiac cycle, said anatomical feature of interest having a different shape at different phases of the cardiac cycle, the plurality of ultrasound images covering at least two cardiac cycles during which the invasive medical device is displaced relative to the anatomical feature of interest; compile a plurality of groups of the ultrasound images, wherein the ultrasound images in each group belong to the same phase of said cardiac cycles; and for each group: determine the displacement of the invasive medical device relative to the anatomical feature of interest between at least two ultrasound images in said group; and generate an augmented ultrasound image from one of the ultrasound images of the at least two ultrasound images by removing a shadow region (17) on the anatomical feature of interest caused by the invasive medical device from said ultrasound image based on the determined displacement of the invasive medical device. Also disclosed are an ultrasound imaging system comprising such an ultrasound image processing apparatus, a method to be implemented by such an ultrasound image processing apparatus and a computer program product facilitating the implementation of such a method.

    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.
