Patent number: 9795239Abstract: A connector for attaching a reference array in a fixed positional relationship with respect to a patient to be covered by a sterile drape in an attachment area, includes a support to be situated below the drape and a clamping element which is to be situated above the drape and can directly or indirectly hold the reference array or a reference array adaptor, wherein the clamping element clamps the support, with the drape caught between the two, by at least two distinct clamps which clamp the support from at least partly opposing directions in such a way that the positional shift in the clamping element as a result of clamping the drape at the clamping position is compensated for, such that its overall positional shift is substantially zero. A method attaching a reference array in a fixed positional relationship relative to a patient above a sterile drape is also provided.Type: GrantFiled: June 13, 2017Date of Patent: October 24, 2017Assignee: Brainlab AGInventors: Stephan Karasz, Rupert Heigl, Norman Plassky, Brian Vasey

Publication number: 20160267659Abstract: A data processing method for co-registering a medical 3D image dataset and a spatial reference (27), comprising the steps of: acquiring the 3D image dataset, wherein the 3D image dataset represents a medical CT image, a medical MR image or an angiograph of at least a part (20) of a patient and a set of hybrid markers (11); detecting the positions of the hybrid markers (11) in the 3D image dataset so as to obtain a scan matrix representing the arrangement of the set of hybrid markers (11) in the 3D image dataset and the position of the scan matrix in the 3D image dataset; acquiring the positions of the hybrid markers (11) with respect to the spatial reference (27), so as to obtain an image matrix (22a) representing the arrangement of the set of hybrid markers (11) in three-dimensional space and the position of the image matrix (22a) relative to the spatial reference (27); and co-registering the scan matrix and the image matrix (22a).Type: ApplicationFiled: December 11, 2013Publication date: September 15, 2016Inventors: Brian VASEY, Rupert HEIGL, Hubert GOETTE

Patent number: 8861828Abstract: The invention relates to a method for positionally correlating, with computer assistance, patient image information included in image data generated by a magnetic resonance scanner and fiducial patient markers represented in the image data, wherein a positional relationship between the patient image information and the fiducial markers is determined by taking into consideration at least the following parameters: a) the material properties of the fiducial markers; b) image generation data included in the image data or provided with the image data; c) the resonance frequency recording mode of the magnetic resonance scanner; and d) any relative positional shift between the patient data and the fiducial markers resulting from the combination of the parameters a) to c). The invention also relates to the use of such a positional correlation in a method for registering patient image data and in a method for navigationally assisting a medical procedure.Type: GrantFiled: November 26, 2009Date of Patent: October 14, 2014Assignee: Brainlab AGInventors: Martin Edlauer, Brian Vasey
