  • Patent number: 11657519
    Abstract: A method for deformation correction includes receiving a preoperative 3D image data set from an examination region of an examination object, generating a segmented 3D image data set by segmenting an anatomical structure in the preoperative 3D image data set, and acquiring image data from the examination region. A medical object is arranged in the examination region. The medical object is identified in the image data, and the segmented 3D image data set is registered with the image data. An overlay data set is generated and displayed based on the segmented 3D image data set and the image data.

  • Publication number: 20220354588
    Abstract: A method for providing a corrected dataset includes receiving a preoperative dataset having an image and/or a model of an examination region in an examination subject. Intraoperatively, a first part of a medical object is arranged in the examination region and a second part of the medical object is arranged outside the examination subject. Positioning information relating to a spatial positioning of the second part of the medical object is received. An entry angle of the medical object into the examination subject is determined using the positioning information. An intraoperative dataset having an image of the examination region is received. A conversion instruction is determined based on the entry angle of the medical object to minimize a deviation between the preoperative and the intraoperative dataset, and the corrected dataset is generated by applying the conversion instruction to the preoperative dataset. The corrected dataset is provided.
