Publication number: 20240104727Abstract: A computer-implemented technique for a user-specific selection of a machine-trained model for determining an implant-related parameter. A set of different machine-trained models is provided. Each model is indicative of a dedicated implant-related parameter for a dedicated patient anatomy. The method may include receiving first patient image data indicative of a patient anatomy in which an implant is to be placed, and applying at least one first model from the set of models on the first patient image data to determine an implant-related parameter. The determined implant-related parameter is suggested to a dedicated user, and feedback is received from the user on the suggested implant-related parameter. The user feedback includes one of a confirmation of the suggested implant-related parameter and an adaptation thereof. At least one second model from the set of models that is to be applied on second patient image data may be selected, based on the user feedback.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Applicant: Stryker European Operations LimitedInventors: Oliver Weede, Florian Herrmann

Patent number: 11911149Abstract: A technique for processing patient-specific image data for computer assisted surgical navigation. A database is provided including multiple first data sets of two- or three-dimensional image data. Each first data set is representative of first shape data or first biometric data of a skin surface of at least one patient. The method further comprises obtaining, by an optical camera system, a second data set of two- or three-dimensional image data of a skin surface of a particular patient and deriving second shape data or second biometric data of the skin surface from the second data set.

Patent number: 11624638Abstract: A flow measuring device detecting a fluid volume quantity since a start of a measurement includes a processing device determining a current flow rate parameter at measurement times using measurement data of a sensor, to increase a volume quantity based on a current flow rate parameter when operating in a first operating mode, and to keep the volume quantity constant when operating in a second mode. The processing device stores the current flow rate parameter for each measurement time in a data memory, resulting after several measuring times in storing previous flow rate parameters determined at these measuring times. Upon satisfying a switchover condition, depending on the current flow rate parameter, during operation in the second mode, the processing unit switches over to the first mode, and the volume quantity increases as a function of the current flow rate parameter and a predefined number of previous flow rate parameters.Type: GrantFiled: September 21, 2020Date of Patent: April 11, 2023Assignee: Diehl Metering GmbHInventors: Florian Herrmann, Alexander Hofmann, Marcus Wetzel, Frederik Neder
