    摘要： 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 an 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, a method to be implemented by such an ultrasound image processing apparatus and a computer program product facilitating the implementation of such a method.

    摘要： The present invention relates to a method for evaluating the start of an assay in a fluidic chamber, wherein said start of the assay is based on the dissolving of a reagent in a region of interest in said fluidic chamber. The method may be based on the detection of an optical effect in the region of interest caused by the dissolving of the reagent, comprising the steps: obtaining an optical signal from one or more sub-sections of said region of interest; processing said optical signal to a Boolean signal; and defining the start of the assay based on said Boolean signal. The present invention also relates to a method for evaluating the start of an assay comprising an electrical detection of a change in the conductivity or permittivity of fluid due to the dissolving of reagent as mentioned above. Furthermore, the invention relates to a program element or computer program for evaluating the start of an assay and to an evaluation system for determining the start of an assay, comprising a computer processor, memory, and (a) data storage device(s), the memory having programming instructions to execute such a program element or computer program.

    摘要： The invention relates to a computer implemented method of determining a boundary of a tumor region or other diseased tissue. Hyper- or multispectral image data of a tissue sample comprising a tumor region or other diseased tissue is taken. The analysis comprises a morphological analysis and a spectral analysis of the hyper- or multispectral image data resulting in a morphological tumor boundary and a spectral tumor boundary or a morphological diseased tissue boundary and a spectral diseased tissue boundary. These two boundaries are combined resulting in a combined tumor boundary or combined diseased tissue boundary, wherein an indication of reliability of the combined tumor boundary or combined diseased tissue boundary is given.

    摘要： 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.
