  • Patent number: 11006923
    Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

  • Publication number: 20200151882
    Abstract: The following relates generally to image segmentation. In one aspect, an image is received and preprocessed. The image may then be classified as segmentable if it is ready for segmentation; if not, it may be classified as not segmentable. Multiple, parallel segmentation processes may be performed on the image. The result of each segmentation process may be marked as a potential success (PS) or a potential failure (PF). The results of the individual segmentation processes may be evaluated in stages. An overall failure may be declared if a percentage of the segmentation processes marked as PF reaches a predetermined threshold.

  • Patent number: 10453174
    Abstract: An image registration system employs an endoscope and an endoscope controller. In operation, the endoscope generates an intra-operative endoscopic image of a vessel tree (e.g., an arterial tree or a venous tree) within an anatomical region, and the endoscope controller image registers the intra-operative endoscopic image of the vessel tree to a pre-operative three-dimensional image of the vessel tree within the anatomical region. The image registration includes an image matching of a graphical representation of each furcation of the vessel tree within the intra-operative endoscopic image of the vessel tree to a graphical representation of each furcation of the vessel tree within the pre-operative three-dimensional image of the vessel tree.

  • Patent number: 9700737
    Abstract: The invention relates to a brachytherapy apparatus (1) for applying a brachytherapy to a living object. The brachytherapy apparatus comprises a planning unit (14) for determining a placing plan defining placing positions and placing times for one or several radiation sources within the living object and close to a target region. The placing plan is determined such that the placing times are within a treatment time window determined by a treatment time window determination unit (13), wherein within the treatment time window a change of a spatial parameter of the living object caused by swelling is minimized. An adverse influence on the brachytherapy due to swelling can thereby be minimized, which improves the quality of the brachytherapy.
