Patent number: 11938344Abstract: Provided is a method of positioning a patient for radiation treatment and/or of monitoring a position of the patient during radiation treatment. The method includes providing surface data from a 3D surface scanner indicative of a surface of a body part of the patient to be irradiated in the radiation treatment. Surface data are calibrated with respect to a relative position of the 3D surface scanner and an isocenter position of a radiation treatment apparatus. A beam path of a radiation beam is determined based on planning data for the radiation treatment and intersected with a part of the surface of the patient represented by the surface data. Further, at least a first portion of the patient's surface located inside the beam path and/or at least a second portion of the patient's surface located outside the beam path is calculated.Type: GrantFiled: July 8, 2019Date of Patent: March 26, 2024Assignee: Brainlab AGInventors: Hagen Kaiser, Michael Stead

Patent number: 11928828Abstract: Disclosed is a computer-implemented method of determining a spatial relationship between planning image data and current surface data which leads to improved surface registration accuracy by considering the elasticity and deformability of the tissue. The knowledge about the tissue can be estimated based on type of tissue and atlas information. For the process of generating surface registration points on specific anatomical regions, e.g. the face or forehead, are acquired with a classical navigated pointer or laser pointer. It is also possible to acquire points with surface scanners. Confidence values defining a probability for certain parts of the surface registration points being deformed in comparison to a planning image are read from atlas data and used to compensate for the deformation in the registration between the surface registration points and the planning image in order to render the registration valid.Type: GrantFiled: May 28, 2019Date of Patent: March 12, 2024Assignee: BRAINLAB AGInventor: Sebastian Stopp
