Abstract: Data privacy is a major concern when accessing and processing sensitive medical data. Homomorphic Encryption (HE) is one technique that preserves privacy while allowing computations to be performed on encrypted data. An encoding method enables typical HE schemes to operate on real-valued numbers of arbitrary precision and size by representing the numbers as a series of polynomial terms.

Abstract: A value indicative of an ejection fraction, EF, of a cardiac chamber of a heart is based on a temporal sequence of cardiac magnetic resonance, CMR, images of the cardiac chamber. A neural network system has an input layer configured to receive the temporal sequence of a stack of slices of the CMR images along an axis of the heart. The temporal sequence is one or multiple consecutive cardiac cycles of the heart. The neural network system has an output layer configured to output the value indicative of the EF based on the temporal sequence. The neural network system has interconnections between the input layer and the output layer and is trained with a plurality of datasets. Each of the datasets comprises an instance temporal sequence of the stack of slices of the CMR images along the axis over one or multiple consecutive cardiac cycles for the input layer and an associated instance value indicative of the EF for the output layer.

Abstract: CMR imaging is synthesized, and/or machine learning for a CMR imaging task uses synthetic sample generation. A machine-learned model generates synthetic samples. For example, the machine-learned model generates the synthetic samples in response to input of values for two or more parameters from the group of electrocardiogram (ECG), an indication of image style, a number of slices, a pathology, a measure of heart function, sample image, and/or an indication of slice position relative to anatomy. The indication of image style may be in the form of a latent representation, which may be used as the only input or one of multiple inputs. These inputs provide for better control over generation of synthetic samples, providing for greater variance and breadth of samples then used to machine train for a CMR task.

Abstract: User interface customization based on user navigational signals is described herein. A computer system causes a device to present first information associated with a first item in a first network page. The computer system receives first data indicating a first interaction with the first information and determines whether the first interaction corresponds to a first request for information about a set of items associated with the first item or to a second request for a removal of the presentation of the first information. If the first interaction corresponds to the first request, the computer system causes the device to present a second network page that shows second information associated with a second item of the set of items. If the first interaction corresponds to the second request, the computer system causes the device to remove the first information from being presented in the first network page.

According to an example, declarative intents are received indicative of a use case for which a cluster of a container orchestration platform is to be deployed within an edge site that is to be created based on infrastructure associated with a private network. A deployment template is created by performing intent translation on the declarative intents and based on a set of constraints. The deployment template identifies the container orchestration platform selected by the intent translation. The deployment template is then executed to deploy and configure the edge site, including provisioning and configuring the infrastructure, installing the container orchestration platform on the infrastructure, configuring the cluster within the container orchestration platform, and deploying a containerized application or portion thereof on the cluster.

Abstract: For shape determination of cardiac anatomy with a medical imager, irregularities in motion, poor image quality, and misalignment of imaging planes are counteracted by a process relying on alignment of contours in combination with selection and fitting of a motion model. Contours are extracted from 2D images and aligned for each frame, which is extracted from the sequence of 2D images. The alignment may use a translation for each frame and rotation across frames for improved performance. A motion model is fit to the aligned contours and tested. If insufficient (greater than threshold difference), other motion models are aligned and tested. Motion models may be created on demand for improved performance. If sufficient, the shape of the heart structure is determined from the fit model.
