  • Patent number: 10332238
    Abstract: Image processing method or apparatus (IP) to transform a 3D image data set (DS) into a visually protected one (DSX). The 3D image set includes an object region (OR) and a background region (BR) that defines s silhouette of an imaged object (P). An inadvertent or malicious direct volume rendering of the silhouette (IF) of the object is prevented by applying a randomization operation to at least the background region (BR).

  • Patent number: 10251594
    Abstract: Minimally-invasive spinal inventions are often performed using fluoroscopic imaging methods, which can give a real-time impression of the location of a surgical instrument, at the expense of a small field of view. When operating on a spinal column, a small field of view can be a problem, because a medical professional is left with no reference vertebra in the fluoroscopy image, from which to identify a vertebra, which is the subject of the intervention. Identifying contiguous vertebrae is difficult because such contiguous vertebrae are similar in shape. However, characteristic features, which differentiate one vertebra from other vertebra, and which are visible in the fluoroscopic view, may be used to provide a reference.

  • Publication number: 20190059839
    Abstract: The invention relates to an apparatus configured to display an aortic valve image and an indicator when the aortic valve is in its open-state and/or when the valve is in its closed-state. The indicator is supposed to be in an overlay to the image of the aortic valve, such that a physician can see on the same display image the information needed to advance a guide wire or catheter through the aortic valve of a heart. This may prevent damaging ensures not to damage the aortic valve. The physician receives the relevant information, when the aortic valve is in its open-state and thus being in a state to be passed by the catheter. The information, whether the aortic valve is in its open-state or in its closed-state, corresponds to the systolic phase and the distal phase of the heart, respectively. The information, when the heart is in its systolic phase and when it is in the diastolic phase may be extracted from an ECG measurement.

  • Publication number: 20180064409
    Abstract: A system and method are provided for displaying medical images. A first viewport is generated which shows a part of a first medical image which shows a region of interest. A second viewport is generated which shows a part of a second medical image which shows a corresponding region of interest, e.g., representing a same anatomical structure or a same type of anatomical structure. In order to establish this ‘synchronized’ display of regions of interest, a displacement field is estimated between the first medical image and the second medical image. However, the displacement field is not used to deform the second medical image. Rather, the displacement field is used to identify the corresponding region of interest and thereby which part of the second medical image is to be shown. It is thus avoided that the second medical image itself is deformed, which would typically also deform the region of interest and thereby impair its assessment.
