Abstract: According to the present invention, a plurality of image pairs, each consisting of a fluoroscopic image and an angiographic image taken from the same position and the same viewing direction onto the patient, is acquired. A live fluoroscopic image is registered individually with each fluoroscopic image within the image pairs, such that the spatial relationship between the live fluoroscopic image and the fluoroscopic images, and thus with the angiographic images and the image pairs in general, becomes known. Angiographic information representing the vascular structure can then be taken from those parts of the angiographic images within the image pairs which overlap with the live fluoroscopic image and be overlayed over the live fluoroscopic image.

Abstract: The disclosed computer-implemented method of detecting at least one foreign object in one or more intraoperative images encompasses the provision and use of one or more intraoperative images, which are compared to expected image content. This also includes particularly the use of live intraoperative video data that are acquired and used in the computer-implemented method defined herein. The method further encompasses the creation, i.e. the calculation and or provision, of expected image content based on several different inputs. Such creation of expected image content can be based on e.g. data associated with the patient's body undergoing a medical procedure, parameters that are indicative of said medical procedure, and/or imaging parameters of the individual imaging device used to generate said one or more intraoperative images.

Abstract: According to the present invention, one or more image pairs, each consisting of a fluoroscopic image and an angiographic image taken from the same position and the same viewing direction onto the patient and each being a non-stitched image, are acquired. A live fluoroscopic image is registered individually with the fluoroscopic image within the at least one of the one or more image pairs, such that the spatial relationship between the live fluoroscopic image and the at least one fluoroscopic image, and thus with the one or more angiographic images and the one or more image pairs in general, becomes known. Angiographic information representing the vascular structure can then be taken from those parts of the angiographic images within the one or more image pairs which overlap with the live fluoroscopic image and be overlayed over the live fluoroscopic image.

Abstract: A method for determining arrangement data which represents an arrangement of measurement points on an anatomical structure of a patient, wherein the arrangement data is individually determined for different regions of the anatomical structure.

Abstract: A method for determining a characteristic property of an anatomical structure from scan data which represents the position of scan points on the surface of the anatomical structure, wherein a spatial region is defined, the scan points which lie in the spatial region are determined, and the scan points which are determined to be lying in the spatial region are used to determine the characteristic property.

Abstract: A method for selecting a femoral implant based on models of a femoral neck and/or a femoral head of a patient is provided. A femoral neck model and/or femoral head model is produced from three-dimensional reference point spatial positions of the femoral neck or head, and a base size of a femoral implant model is ascertained based on the femoral head model. A femoral implant model is produced from the base size, and the implant model is positioned at a position in or on the femoral head model. An implant value is ascertained that indicates how many or what proportion of the ascertained reference point spatial positions are outside the implant model. If the implant value exceeds a predetermined value, the implant model is repositioned and the process is repeated. If the implant value does not exceed the value, an appropriate size and position of the implant is determined.

Abstract: A method for selecting a femoral implant based on models of a femoral neck and/or a femoral head of a patient, includes: a) detecting reference points on the femoral neck and/or femoral head of the patient; b) registering the femoral neck and/or femoral head based on three-dimensional reference point spatial positions of the detected reference points; c) producing a femoral neck model and/or femoral head model from the three-dimensional reference point spatial positions; d) ascertaining a base size of a femoral implant model based on the femoral head model; e) producing a femoral implant model based on the base size of the femoral implant model; f) positioning the femoral implant model at a position in or on the femoral head model; g) ascertaining an implant value that indicates how many or what proportion of the ascertained reference point spatial positions are outside the femoral implant model; h) determining if the implant value exceeds a predetermined limit value; and i) if the implant value exceeds the l
