With Means For Determining Position Of A Device Placed Within A Body Patents (Class 600/424)
  • Patent number: 10319091
    Abstract: A three-dimensional subtraction angiography image data set including a target region of the patient is acquired. A region of interest is selected. An imaging geometry is defined for monitoring the intervention using an X-ray device. The image-obscuring blood vessels that superimpose the region of interest in the imaging geometry and imaging zones that show fractions of the image-obscuring blood vessels in the imaging geometry are determined. Path information relating to the image-obscuring blood vessels is defined. The information relating to the path is input into a two-dimensional forward projection data set. A fluoroscopic image is acquired in the imaging geometry. Pixels showing the image-obscuring blood vessels in the fluoroscopic image are determined using the path information and image intensity information from the fluoroscopic image. A masked image of the image-obscuring blood vessels is subtracted. The fluoroscopic image that has been modified is displayed.

  • Patent number: 10245110
    Abstract: A method of planning an image-guided interventional procedure to be performed on a patient, where expected motion of the patient, such as that of a breathing cycle, is determined on a sequence of preoperative images, and the procedure trajectory is planned accordingly. The method takes into account the initial positions of the interventional entry, the target region, and any obstructions or forbidden regions between the entry point and the target region, and uses object tracking methods of image processing on the preoperative images to determine how the positions of these three elements change relative to each other during the patient's motion cycle. The method may automatically search in at least some of the preoperative images taken at different temporal points of the motion cycle, for a path connecting the entry point with the target and avoiding the obstacles, which provides minimal lateral pressure on the patient's tissues.

  • Patent number: 10242450
    Abstract: The present invention relates to an ultrasound imaging system (10) for inspecting an object (97) in a volume (40). The ultrasound imaging system comprises an image processor (36) configured to conduct a segmentation (80) of the object (97) simultaneously out of three-dimensional ultrasound mage data (62) and contrast-enhanced three-dimensional ultrasound image data (60). In particular, this may be done by minimizing an energy term taking into account both the normal three-dimensional ultrasound image data and the contrast-enhanced three-dimensional image data. By this, the normal three-dimensional ultrasound image data and the contrast-enhanced three-dimensional image data may even be registered during segmentation. Hence, this invention allows a more precise quantification of one organ in two different modalities as well as the registration of two images for simultaneous visualization.

  • Patent number: 10176582
    Abstract: Embodiments of the invention introduce the concept of a virtual fiducial marker (VFM). This marker will not be placed prior to preoperative imaging. It will therefore not initially appear in the preoperative 3D image. Instead, the marker will be virtually placed in the 3D data set prior to surgery, and as such the marker does not even need to be attached to the patient, if the patient is not expected to move during surgery. The idea behind such a VFM comes from the observation that there is a big variation in the difficulty of an image based registration depending on the quality of the images and their field of view. However, provided two initial registrations to high quality wide field of view images can be carried out, it then becomes possible to use these registrations to insert a virtual fiducial marker within the 3D preoperative image. Once inserted it may then be used to obtain a starting position for a registration procedure, and particularly to obtain in-plane translations.

    Abstract: Provided herein are system and methods for monitoring and guiding thermal therapy procedures within a human or animal tissue. The system comprises a therapeutic module configured to apply thermal treatment to a subject; an ultrasound imaging module; an optoacoustic imaging module; a processing module connected to both ultrasound and optoacoustic based imaging module; and an operating controlling module connected with said processing module and configured to manipulate at least one of said therapeutic module, ultrasound imaging module or optoacoustic imaging module. The calibration method is able to eliminate the inconsistency of optoacoustic based temperature measurements caused by sample-to-sample and spatial variations of Gruneisen parameter for different tissues. The method for temperature-structure imaging is able to generate both two dimensional and three dimensional co-registered structure and temperature images for the tissues inside a region of interest of a subject.

  • Patent number: 10123760
    Abstract: A method for the reconstruction of planning images is based on a plurality of first respiratory cycles of a patient and tomographic raw data recorded at the same time as the first respiratory cycles being received. A reference cycle is determined based on respiratory cycles of the patient, in particular based on the first respiratory cycles of the patient. A reference cycle is subdivided into temporally equidistant reference phases, a reference amplitude being associated with each reference phase. The reference amplitudes are not equidistantly scanned therefore. Furthermore, the first respiratory cycles of the patient are subdivided into first phases, the temporal positions of the first phases each being based on one of the reference amplitudes. Reconstruction of planning images based on first intervals of the raw data follows, wherein the first intervals correspond to the first phases.

  • Patent number: 10111723
    Abstract: A robotic catheter control system includes a collision detection logic configured to determine a collision metric indicative of a collision between a medical device that is manipulated by the robotic control system and an object. The object may be an anatomical feature or can be another medical device, including another device being manipulated by the robotic control system. The collision detection logic produces virtual representations of the medical device and the object and uses these representation to determine collision. Geometrical solids, such as spheres, are used to represent the outer surfaces of the devices and the logic determines whether the respective surfaces intersect, thereby indicating collision. Collision avoidance involves estimating future device poses and then computing an alternate path computation so as avoid predicted collision(s).

  • Patent number: 10111678
    Abstract: A medical manipulator is disclosed, which includes a multiple-degree freedom arm which can be mounted with a medical instrument, an insertion port position which indicates a spatial position of an insertion port for inserting the medical instrument mounted in the multiple-degree freedom arm into a human body is retained, and the multiple-degree freedom arm is controlled so as to insert the medical instrument into the human body from the retained insertion port position. The multiple-degree freedom arm is driven under operational restriction in which movement of the medical instrument is restricted by the insertion port position after the medical instrument is inserted from the insertion port position. The multiple-degree freedom arm is driven so as to move a predetermined portion of the medical instrument to spatial coordinates instructed by a user while maintaining a state where the medical instrument passes through the insertion port position under the operational restriction.

  • Patent number: 10108882
    Abstract: Methods to access place data such as local business reviews, restaurant menus, merchant details, and other point-of-interest information directly from images is provided. Methods of the invention can enable users to interact with places digitally through pictures and videos. While digital images are captured, the location and orientation of the camera is also recorded. The method compares the digital images captured by the camera with images synthetically generated by a virtual camera placed inside a 3D geospatial model consisting of, for example, LIDAR, satellite image, and GIS data. The camera location and orientation of the virtual camera is iteratively refined until the synthetically generated image matches the camera image. The place information from the synthetically generated image is transferred to the actual picture once the match is completed. User can access the transferred place information directly through the picture.
