Publication number: 20220392173Abstract: According to a method for virtual enhancement of a camera image, a camera image depicting an object is generated. A geometric description of a virtual auxiliary object as a surface in space and a pose of the auxiliary object with respect to the object are specified, wherein the auxiliary object separates part of the object from the rest of the object. An enhanced image is generated based on a superimposition of the camera image with a representation of the auxiliary object depending on the geometric description and the pose of the auxiliary object by a computing unit and displayed on a display device. The enhanced image is generated and displayed in such a way that the auxiliary object has a spatially variable transparency.Type: ApplicationFiled: May 23, 2022Publication date: December 8, 2022Inventors: Alois Regensburger, Amilcar Alzaga

Patent number: 11282211Abstract: The disclosure relates to a medical imaging device, a method for supporting medical personnel, a corresponding computer program product, and a corresponding computer-readable storage medium. In the method, a 3D data record is received from a first imaging modality and image data of an examination object is received from a second imaging modality. Different tissue regions of the same organ are imaged with different imaging properties at least under the second imaging modality. A tissue boundary is detected between the tissue regions in the image data. For registration of the image data with the 3D data record, the tissue boundary is aligned at a corresponding tissue boundary in the 3D data record. In addition, or alternatively, based on the tissue boundary, an automatic movement compensation takes place of a movement of the examination object which has occurred during the generation of the image data.Type: GrantFiled: January 21, 2020Date of Patent: March 22, 2022Assignee: Siemens Healthcare GmbHInventors: Alois Regensburger, Amilcar Alzaga

Patent number: 10951837Abstract: A camera image is acquired by a camera and a structure that is optically concealed in the camera image is acquired by a material-penetrating acquisition modality. A stereoscopic depth location of a common reference point is then fixed at a predetermined value. The stereoscopic representation is then generated from the camera image, and an overlay image is generated based on the concealed structure. In this case, a depth location of the camera image is fixed at the depth location of the reference point, and, as a function thereof, a depth location of the overlay image is adjusted in relation to the depth location of the reference point, such that in the stereoscopic representation, the overlay image appears realistically in front of and/or behind an optically opaque part in the recording direction of the camera image.Type: GrantFiled: July 26, 2019Date of Patent: March 16, 2021Assignee: Siemens Healthcare GmbHInventors: Amilcar Alzaga, Alois Regensburger
