Abstract: Methods and computer systems are described that classify a cardiogram as being an atrial fibrillation (AF) or ventricular fibrillation (VF) cardiogram, automatically detect an AF epoch within an AF cardiogram, and automatically detect a VF epoch within a VF cardiogram. A classification and identification (C&I) system includes a classification system, an AF identification system, and a VF identification system. The C&I system processes cardiograms collected from patients to classify the cardiograms as being AF cardiograms or VF cardiograms and to identify AF epochs within the AF cardiograms or VF epochs within the VF cardiograms. The C&I system may then identify an AF source location of an AF based on the AF epochs and a VF source location of a VF based on the VF epochs. The C&I system may display a graphic of a heart that includes an indication of a source location.

Abstract: A method for manufacturing a low-angle blazed grating on a semiconductor or silicon substrate, includes spin-coating the substrate with resist layer or hydrogen or polysilsesquioxane, being 100-1000 nm or few hundred nanometers thick, applying grayscale irradiation lithography exposure to the resist layer, generating a dose modulated pattern therein, varying in response to absorbed energy density from irradiation lithography exposure. The coated, irradiated substrate is developed in solution, such as TMAH or NaOH, enabling a blazed profile having structures of thickness-dependent diffusion barriers or SiO2, with 0-1000 nm height to emerge. Thermal oxidation in oxygen atmosphere at elevated temperature with the developed substrate, converts the upper silicon substrate layer into SiO2 to a depth depending on the thickness of the pattern in the resist layer above. Hydrofluoric acid fluid removes the SiO2, creating low-angle low-roughness blazed grating structure on silicon substrate.

Abstract: A system is provided for generating and displaying a sequence of three-dimensional (3D) graphics that illustrate motion of the heart over a cardiac cycle. The system generates a start heart wall mesh and an end heart wall mesh that represent a start geometry and an end geometry of a heart wall derived from a start 3D image and an end 3D image. The system then generates one or more an intermediate heart wall 3D meshes based on an intermediate geometry of the heart wall. An intermediate geometry is interpolated based on the start geometry and the end geometry factoring a start time of a start heart wall mesh, an end time of the end heart wall mesh, and an intermediate time for the intermediate heart wall mesh. The system then displays in sequence representations the heart wall 3D meshes to illustrate the motion.

Abstract: A system is described for generating a revascularization score for a blockage of a coronary artery in a heart. The system accesses indications of viability of myocardial tissue in the heart, a blockage state of the blockage that includes a blockage location and a blockage amount, and the perfusion territory of the myocardial tissue. Based on the myocardial tissue state, blockage state, and perfusion territory, the system generates a revascularization score for the blockage. The system generates a graphic of the heart that illustrates coronary arteries, myocardial tissue state, blockage state, and the revascularization score. The system displays the graphic to provide a visual representation of the revascularization score for the blockage of the coronary artery.

Abstract: Systems are provided for synthesizing leads of an electrocardiogram (ECG) based on a subject ECG collected from a subject and converting a nonstandard ECG based on a nonstandard placement of electrodes to a standard ECG with a standard placement of electrodes. The described systems may generate simulated ECGs based on simulations of electrical activity of hearts having different heart configurations. From each simulation, simulated ECGs are generated assuming a specification of electrode position(s) for each lead of an ECG. The systems identify a simulated ECG that is similar to the subject ECG. Based on the simulation from which that simulated ECG was generated, the systems identify a synthesized ECG or converted ECG.

Abstract: A system is provided that employs a machine learning (ML) decision tree to provide a treatment analysis for an arrhythmia. The ML decision tree includes decision nodes (non-leaf nodes) and treatment analysis nodes (leaf nodes). Each decision node corresponds to a feature derived from electronic health records and has branches corresponding to feature values. A treatment analysis node corresponds to a treatment analysis based on feature values of a path from the root node to that treatment analysis node. To provide a treatment analysis for a candidate, the system identifies a path from the root node to a treatment analysis node based on a candidate feature vector derived from an electronic health record of the candidate and outputs the treatment analysis of the treatment analysis node of the identified path.

Abstract: In one or more embodiments, a system generates a navigable interface for traversing sets of content based on system-determined relationships between the sets of content. The system uses a trained machine learning model to determine characteristics, such as layout, for sets of content. The characteristics are mapped to a content type. The system organizes the sets of content, based on respective content type, into a set of pages of a multipage navigable interface. Furthermore, the system selects navigational relationships between the sets of content based on respective content type. The navigational relationships are implemented via interface elements that allow for navigation between the pages of the navigable interface including corresponding sets of content.
