  • Publication number: 20150126864
    Abstract: The invention relates to an image generation apparatus (1) for generating an image of a deformable object (5) like a woman's breast. A first image generating unit (2) like an ultrasound head generates a first image of the object covered by a flexible cover element (6), wherein a shape sensing and localization unit (10), in particular, a fiber-optic shape sensing and localization unit, determines the shape and position of the cover element. The apparatus further comprises a position determination unit (11) for determining the position of the first image generating unit relative to the cover element. Information about the deformation of the deformable object with respect to the first image can therefore be provided, which can facilitate reviewing the first image, especially reviewing of breast images. For instance, this information can facilitate a comparison of breast images acquired by different imaging modalities.

  • Patent number: 8983575
    Abstract: The invention relates to a device and a method for the determination of the position of a catheter in a vascular system (8). In this, the measured positions (r1, r2) of two magnetic localizers at the tip of a catheter are displaced by correction vectors (k1, k2) while optimizing a quality dimension. The quality dimension includes a component taking account both of the deviation of the measured positions (r1, r2) from the vascular layout and of the deviation of the associated orientation (r2?r1) from the orientation of the vascular layout according to a vascular map. In addition, the quality dimension may include components which evaluate the measured shape of the catheter compared to the vascular map. An additional correction step can further ensure that the corrected positions (r1?, r2?) correspond to the preset fixed distance (d) of the localizers (4, 5).

  • Patent number: 8145012
    Abstract: The invention relates to a device and a process, with which images of different imaging methods can be registered, for example preoperatively obtained 3D X-ray images (A) and intra operatively obtained ultrasound images (B). First transformed images (A?,B?) are then generated in a data processing device (10), which are aligned to each other with regard to the peculiarities of each imaging method. Particularly from the three dimensional CT-image (A), can be generated a two dimensional image (A?) which adheres to the characteristic means of representation of an ultrasound system, while shaded areas behind bones and/or gas-filled volumes can be blended out. With a feature-based registration of the transformed images (A?, B?) errors are avoided, which are traced back to artifacts and peculiarities of the respective imaging methods.

  • Patent number: 7907989
    Abstract: The invention relates to a system and an imaging method for visualizing areas (2) in a moving environment within the body of a patient (1), wherein the position of one or more markers, which are connected to an interventional device (4), is determined and used to determine the position of the areas (2) and/or of the interventional device (4) in images (6) which are recorded of the areas (2) and of their environment. According to the invention, the markers used are active locators which independently of the method used to record the images (6) generate data or signals for determining their position. Such an imaging method, which preferably uses electromagnetic locators, allows a considerably more robust representation of the visualized areas (2), with elimination of movements, than is possible using passive markers.

  • Patent number: 7729743
    Abstract: The invention relates to a method and an arrangement for the intravascular or intracardial navigation of a catheter (5). Using an X-ray fluoroscopy device (1), firstly an image database of 2D images is generated, where at the same time as each 2D image (I) is taken the associated heartbeat phase is recorded using an ECG (8). During the catheter intervention, the position of the catheter (5) is measured by means of a position measurement unit (6), and at the same time the ECG and preferably also a signal that is dependent on the breathing movement are recorded. The current spatial position of the catheter (5) that is measured is then assigned the 2D image of the image database which corresponds in terms of the heartbeat phase and also possibly in terms of the breathing phase, on which image the position of the catheter can be represented.

  • Publication number: 20080294034
    Abstract: The invention relates to a device and a method for the determination of the position of a catheter in a vascular system (8). In this, the measured positions (r1, r2) of two magnetic localizers at the tip of a catheter are displaced by correction vectors (k1, k2) while optimizing a quality dimension. The quality dimension includes a component taking account both of the deviation of the measured positions (r1, r2) from the vascular layout and of the deviation of the associated orientation (r2?r1) from the orientation of the vascular layout according to a vascular map. In addition, the quality dimension may include components which evaluate the measured shape of the catheter compared to the vascular map. An additional correction step can further ensure that the corrected positions (r1?, r2?) correspond to the preset fixed distance (d) of the localizers (4, 5).

  • Patent number: 7263160
    Abstract: In the field of airport baggage inspection, a multi-level screening procedure is used. When a first level screening system (18) detects a “suspicious region” inside a bag, it is transferred to a next level system (2) where the bag gets rescanned. According to the present invention, a device/method is provided for finding and tracking the suspicious region inside the baggage which allows to reduce the area to be rescanned significantly. For this purpose, the image from the first level system together with the position of the suspicious region within the image is transferred from the first level system to the second level system. On arrival of the bag at the second level (21), a simple X-ray transmission image is measured using an additional source/detector system (6). The two images are then rigidly registered in order to exactly determine the suspicious region in the second level scanner system.
