摘要： Disclosed is a computer-implemented method of analyzing the setup of an array of acceleration sensors on an anatomical body part of a patient encompasses acquisition of acceleration data using a cranial headset having acceleration sensors and determining an appropriate contact of the acceleration sensor to the patient's head, detecting, marking, filtering out, or removing different kinds of noise as well as acceleration signals which are considered to be due to gross patient movement. This is done to determine whether the setup of the headset on the patient's head is good enough to generate measurement signals of acceptable quality. If this is the case, the headset is subsequently used to acquire continuous datasets of acceleration data which is then evaluated to determine the patient's physiological status.

摘要： A computer-implemented method for estimating a total scatter factor in dose calculation for radiotherapy, wherein a linear accelerator, LINAC, is used to irradiate a medium is presented. In particular, in this method geometric data of the LINAC is received, wherein the geometric data comprises geometric information about collimating devices of a LINAC head of the LINAC. A head scatter factor is determined based on a geometric head model using the received geometric data, wherein the head scatter factor quantifies a scatter contribution from the LINAC head. A phantom scatter factor is determined based on an empiric phantom scatter formula using the received geometric data, wherein the phantom scatter factor quantifies a scatter contribution from the irradiated medium. An estimated total scatter factor is determined using the determined head scatter factor and the determined phantom scatter factor. Thus, the proposed method inter alia allows to improve a dose calculation accuracy for complex radiotherapy treatment, in particular including small or multiple opening of the multi leaf collimator.

摘要： 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. In a further step, a comparison between the expected image content and the one or more acquired intraoperative images is conducted, preferably using an image and/or video analysis algorithm for analyzing the at least one acquired intraoperative image and for automatically detecting the at least one foreign object in the intraoperative image.

摘要： Disclosed is a computer-implemented method of planning a position of a tracking reference device for referencing a position in a medical environment. The disclosed method encompasses determination of avoidance regions in which a tracking reference device should not be placed so as to safeguard proper tracking of the tracking reference device and/or an instrument tracking reference device which is attached to a medical instrument. The avoidance region is defined as a region lying, for the point of view of a tracking device for tracking the tracking reference device, in the shadow of an envelope surrounding at least one medical instrument. Additionally or alternatively, an avoidance region may lie in between the position of the tracking device and the envelope to avoid a shadowing, by the tracking reference device, of an instrument tracking reference device attached to the medical instrument. Information describing the position of the at least one avoidance region is displayed to a user, and also information about the position of a region which is suitable for placement of the tracking reference device can be displayed to the user.

摘要： The present invention relates to a computer-implemented medical method, a computer program and a medical system for determining the spatial position of an object to be tracked not only via the surgical microscope, but also via a separate detection system. In case a deviation between the detected spatial positions is recognised, the optical system of the surgical microscope is re- calibrated.
