Publication number: 20240062517Abstract: Disclosed is a computer-implemented method which encompasses registering a tracked imaging device such as a microscope having a known viewing direction and an atlas to a patient space so that a transformation can be established between the atlas space and the reference system for defining positions in images of an anatomical structure of the patient. Labels are associated with certain constituents of the images and are input into a learning algorithm such as a machine learning algorithm, for example a convolutional neural network, together with the medical images and an anatomical vector and for example also the atlas to train the learning algorithm for automatic segmentation of patient images generated with the tracked imaging device. The trained learning algorithm then allows for efficient segmentation and/or labelling of patient images without having to register the patient images to the atlas each time, thereby saving on computational effort.Type: ApplicationFiled: October 27, 2023Publication date: February 22, 2024Inventors: Stefan Vilsmeier, Jens Schmaler

Patent number: 11877809Abstract: Disclosed is a computer-implemented of adapting a biomechanical model of an anatomical body part of a patient to a current status of the patient. The method encompasses determination of a currently executed step of a workflow such as a medical intervention, the result of the determination serving as a basis for adapting and/or updating a biomechanical model of an anatomical body part to the corresponding current status of the patient. The determination of the current workflow step may also be used as basis for controlling an imaging device for tracking entities around the patient or for imaging the anatomical body part or acquiring further data or for urging the user to perform a specific action such as acquisition of information using a tracked instrument such as a pointer. The biomechanical model has been generated from atlas data.Type: GrantFiled: December 18, 2019Date of Patent: January 23, 2024Assignee: BRAINLAB AGInventors: Stefan Vilsmeier, Andreas Blumhofer, Jens Schmaler, Patrick Hiepe

Patent number: 11861846Abstract: Disclosed is a computer-implemented methods of determining distributions of corrections for correcting the segmentation of medical image data, determining corrections for correcting the segmentation of medical image data, training a learning algorithm for determining a segmentation of a digital medical image, and determining a relation between an image representation of the anatomical body part in an individual medical image and a label to be associated with the image representation of the anatomical body part in the individual medical image using the trained machine learning algorithm. The methods encompass reading a plurality of corrections to image segmentations, wherein the corrections themselves may have been manually generated, transforming these corrections into a reference system which is not patient-specific such as an atlas reference system, conducting a statistical analysis of the correction, and applying the re-transformed result of the statistical analysis to patient images.Type: GrantFiled: December 20, 2019Date of Patent: January 2, 2024Assignee: BRAINLAB AGInventors: Stefan Vilsmeier, Andreas Blumhofer, Jens Schmaler

Publication number: 20230260129Abstract: Disclosed is a computer-implemented method of segmenting a medical patient image using an atlas and relating the segmentation result to a model of possible geometric changes to the segmentation result (e.g. for correcting the position of the segmentation of anatomical structures) which consider for example anatomical limitations. The thus-related segmentation result may be used as a basis for changing and/or correcting the position, shape and/or orientation of at least parts of the segmentation result, e.g. by user interaction. The invention also relates to an atlas data set comprising information such as values of the variables of the model of possible geometric changes in relation to the positions of anatomical structures in the atlas.Type: ApplicationFiled: April 25, 2023Publication date: August 17, 2023Inventors: Jens SCHMALER, Andreas GIESE, Andreas BLUMHOFER

Publication number: 20230087494Abstract: Disclosed are computer-implemented methods which encompass determining whether two medical images were taken of the same patient. In a first aspect, this is done by analysing a registration of the two images with one another. The registration may be a direct registration between the two images or an indirect registration, for example via an atlas to which each image is registered. In other aspects, a machine learning algorithm is trained on the basis of image registrations to determine whether the two images were taken of the same patient. The disclosed methods serve the purpose of being able to group medical images together which were taken of the same patient without having to provide or otherwise process data about the identity of the patient.Type: ApplicationFiled: March 26, 2021Publication date: March 23, 2023Inventors: Stefan Vilsmeier, Jens Schmaler

Patent number: 11593519Abstract: Disclosed is a computer-implemented method for generating an anonymized medical image of an anatomical body part of a patient, a corresponding computer program, a program storage medium storing such a program and a computer for executing the program, as well as a medical system comprising an electronic data storage device and the aforementioned computer. The disclosed method encompasses establishing a mapping from a patient image onto an atlas, changing that mapping, and applying the inverse of the changed mapping to the atlas in order to transform image content from the atlas to the patient image in order to achieve a deformed and thereby anonymised appearance of the patient image.Type: GrantFiled: April 7, 2021Date of Patent: February 28, 2023Assignee: BRAINLAB AGInventors: Andreas Blumhofer, Jens Schmaler

Publication number: 20180119826Abstract: A thermal management module is provided that includes a housing, a rotary valve, and a sealing assembly arranged in a passageway of the housing. The sealing assembly includes a main seal, a secondary seal, and a seal support. The main seal is loose-fitting on the seal support and is loose-fitting in the housing, allowing rotation of the main seal. The rotating seal will wear uniformly, thereby reducing wear, and maintain good sealing performance throughout the lifetime of the thermal management module. The rotary valve can be configured with an opening that is asymmetric in relation to an axial direction of the rotary valve, thereby providing a rotational torque for turning the main seal. The opening of the rotary valve can have a die parting line that is inclined relative to the axial direction of the rotary valve, also providing a rotational torque for turning the main seal.Type: ApplicationFiled: May 25, 2016Publication date: May 3, 2018Applicant: Schaeffler Technologies AG & Co.
