Abstract: Disclosed embodiments determine, at an early stage, suitability of an intraoperative image for further intraoperative surgical analysis. The determination of suitability may be made using a first angle (such as a first obturator angle) based on at least three pelvic feature points in a preoperative image, a corresponding second angle (such as a corresponding second obturator angle) based on at least three corresponding pelvic feature points in an intraoperative image, and by comparing the first angle and the corresponding second angle to determine intraoperative image suitability. The first intra-operative image is indicated as suitable for further intraoperative analysis when an absolute value of a difference between the first angle and the corresponding second angle does not exceed a threshold. When the intraoperative image is determined as unsuitable for further intraoperative analysis, an indication of a movement direction for a fluoroscopy camera used to capture the intraoperative image is provided.

Abstract: A system for providing an artificially-intelligent graph database is disclosed. The graph database has significant graph computing capabilities, which are facilitated through the integration of artificial intelligence into the graph database. The capabilities are enabled through the use of unique artificially-intelligent agents that are each responsible for a subgraph of a graph of the graph database. Each artificially-intelligent agent performs computations on the graph-structured data in each subgraph that each agent is responsible for managing. The artificially-intelligent agents may work cohesively together to provide artificial intelligence capabilities to the entire graph database. The graph database may optimize itself through intelligent local management by using the agents.

Abstract: A system and method to identify, convey, and reduce the risk of hip dislocations following hip replacement surgery. Preoperative images are used to identify the pelvic tilt of a patient while the patient is in a sitting position, a standing position, and a supine position. Based on the pelvic tilt and pelvic mobility depicted in the preoperative images, the system can identify a quantitative and/or qualitative risk of hip dislocation when the patient is seated, standing, and lying. During surgery, an intraoperative image can confirm the acetabular cup orientation once implanted and the system can determine the risk of hip dislocation when patient is in the supine position. The system can also extrapolate the dislocation risk when the patient is seated and standing based on acetabular cup position and orientation depicted in the intraoperative image.

Abstract: In an embodiment, a computing system receives a first electronic remittance corresponding to a first electronic payment to a payee. The system determines that the first remittance is in a first, unrecognized format, and responsively presents, to the payee, a user interface for matching electronic remittances to electronic payments. The system receives, via the user interface, field-mapping information between the first format and a second, recognized format. The system receives a second electronic remittance corresponding to a second electronic payment directed to the payee, determines that the second remittance is in the first format, and responsively uses the field-mapping information to convert the second remittance to the second format. The system matches the converted remittance to the second payment, and provides, to the payee, a payment file that indicates a match between the second remittance and the second payment.

Abstract: Some embodiments provide a navigation application with a novel declutter navigation mode. In some embodiments, the navigation application has a declutter control that when selected, directs the navigation application to simplify a navigation presentation by removing or de-emphasizing non-essential items that are displayed in the navigation presentation. In some embodiments, the declutter control is a mode-selecting control that allows the navigation presentation to toggle between normal first navigation presentation and a simplified second navigation presentation, which below is also referred to as a decluttered navigation presentation. During normal mode operation, the navigation presentation of some embodiments provides (1) a representation of the navigated route, (2) representations of the roads along the navigated route, (3) representation of major and minor roads that intersect or are near the navigated route, and (4) representations of buildings and other objects in the navigated scene.
