An ultrasound image processing apparatus includes an image processor arrangement that receives a plurality of ultrasound images. Each ultrasound image shows an invasive medical device relative to an anatomical feature during a cardiac cycle. At different phases of the cardiac cycle, the anatomical feature has a different shape. The ultrasound processing apparatus compiles groups of the ultrasound images with ultrasound images in each group belonging to the same phase of the cardiac cycle. The ultrasound image processing apparatus generates an augmented ultrasound image from one of the ultrasound images by removing a shadow region on the anatomical feature of interest caused by the invasive medical device based on a displacement of the invasive medical device.

Ultrasound image processing

A method for ultrasound image processing having steps of receiving sequences of ultrasound images imaging an anatomical feature of interest during two cardiac cycles one in the absence of, and the other in the presence of, an invasive medical device in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle. The invasive medical device may at least partially obscure the anatomical feature of interest for each ultrasound image of the further sequence. The location of the invasive medical device is tracked and isolated in the ultrasound image, and the isolated invasive medical device is inserted into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location. The method also controls a display device to display the first sequence of ultrasound images including the inserted invasive medical device.

Systems, methods, and apparatuses for reducing or eliminating reverberation artifacts in images are disclosed. Systems including one or more ultrasound probes are disclosed. Apparatuses for providing registration information for an ultrasound probe or probes at different positions are disclosed. A method of combining volume images acquired at different positions to reduce or eliminate reverberation artifacts is disclosed.

Systems, methods, and apparatuses for image artifact cancellation

An image data processing method is for registering two four-dimensional image data sets, each representative of a time-series of three-dimensional image frames. The method comprises an initial pre-registration step in which 3D image frames of the two image data sets are rotated and translated () relative to one another so as to bring into alignment respective dominant motion vectors identified () for each, the dominant motion vector being a 3D motion vector representative of motion of an identified three-dimensional sub-region exhibiting maximal spatial displacement over course of the time series.

Image data processing method, device and system

In 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 including a tumor region or other diseased tissue is taken. The analysis includes 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.

Tumor boundary reconstruction using hyperspectral imaging

Disclosed is an ultrasound image processing apparatus () comprising an image processor arrangement () adapted to receive a first sequence (') of ultrasound images () imaging an anatomical feature of interest () during a first full cardiac cycle in the absence of an invasive medical device () in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle; receive a further sequence () of ultrasound images () imaging the anatomical feature of interest () during a further full cardiac cycle in the presence of the invasive medical device () in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle said invasive medical device () 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.

The present invention relates to a template () and a system () for collecting data of a face of a subject. The system () comprises at least the template () and a camera (). The template () comprises at least one computer-detectable element and allows to take a single image of a face of a subject which is positioned in an opening of the template and to derive subject dimensions of the face of the subject based on this single image. The present invention relates also to according methods.
