Abstract: A network guidelines estimator (NGE) estimates a network load for each software application operating in a test network to determine network load metrics for each software application. A network load estimator (NLE) estimates a network load for one or more software applications concurrently operating in a production network responsive to the network load metrics of each of the one or more software applications. A network load analyzer (NLA) analyzes the network load for the one or more software applications concurrently operating in the production network to determine an actual network load for the production network.

Abstract: A system improves payment claims transactions by analyzing payments transactions to update payment edit rules according to information derived from the transactions. A system adapts rules used for processing claim adjudication data provided by a payer organization concerning a claim for reimbursement for provision of healthcare to a patient previously submitted to the payer organization in a claim. The system includes a data processor for parsing claim adjudication data provided by a specific payer organization in an electronic transaction message to identify data comprising, (a) a payer organization identifier and (b) a reason for rejection of a claim. A rules processor automatically generates a payer specific rule for use in pre-processing a claim for submission to the specific payer identified by the payer organization identifier by translating data comprising the reason for rejection into a logical expression resolvable using data elements in a claim.

Abstract: A workflow system and user interface coordinates information concerning a course of treatment of a patient, as well as data from a treatment device and links appointment data from a scheduling system with actual treatment activity information in order to show a complete timeline of a course of treatment. A user interface system for presenting medication dosage and treatment information includes a display processor for providing data representing a single display image. The single display image presents information identifying treatment received by a patient and treatment scheduled to be received by the patient together with a timeline. The single display image also presents information identifying cumulative dosage of a medication received by a patient and an associated date the cumulative dosage is received by the patient. A command processor initiates presentation of the single display image in response to user command.

Abstract: A system automatically establishes context information (e.g., determining changes to user interface workflows, screens, menus, and access requirements for devices such as monitors, ventilators, and diagnostic equipment) used by a worker in using healthcare information applications based on patient geographic location (e.g., a room or bed or department). The system addresses the need for a user to sign onto a system with each location change and manually change context information which consumes computer, server and network resources and represent a potential security problem. A healthcare system selects information to be provided to a user in response to received location dependent context data. The system includes a proximity detector for wirelessly detecting presence of an identification tag substantially within a predetermined vicinity of the detector. The identification tag is associated with at least one of, (a) a particular processing device and (b) a particular person.

The system includes multiple adaptive signal filters individually having a filtering bandwidth and filtering characteristic programmable in response to received programming data. A noise detector automatically identifies a noise component in a received patient monitoring signal and generates the noise data.

Abstract: A medical signal interface device bidirectionally conveys signals between a patient and patient monitoring devices. The device comprises a bidirectional electrical signal interface that receives and buffers patient parameter monitoring signals received from a patient via patient attached leads and outputs treatment related signals used in applying invasive or non-invasive treatment to a patient. A bidirectional electrical signal processor operates in response to commands received from a control processor and is coupled to the electrical signal interface, for processing received patient parameter monitoring signals using filtering and amplification to provide processed patient monitoring signals for output to at least one patient monitoring device. The bidirectional electrical signal processor processes the treatment related signals for output by buffering the treatment related signals for output to a patient.

Abstract: A medical imaging system generates 3D anatomical images from acquired 2D anatomical images. The system includes a synchronization processor for providing a synchronization signal identifying a particular phase of heart operation of a particular patient. An image acquisition device acquires 2D anatomical images of a patient heart in angularly variable imaging planes over multiple different heart cycles at the particular phase of heart operation in response to the synchronization signal and in response to recorded data indicating imaging previously being performed at particular imaging plane angles. An image processor stores the recorded data to prevent imaging overlap at the particular imaging plane angles and to prevent unnecessary radiation exposure of the patient. The image processor processes 2D images acquired by the image acquisition device of the patient heart in multiple different imaging planes having relative angular separation, to provide a 3D image reconstruction of the patient heart.

A system processes claim data related to provision of healthcare to a patient The system includes a claim data collator for collating data related to a claim for a particular patient for submission to a payer and a source of rules for use in processing collated claim data. A pre-processor submits the collated claim data for processing using the rules to validate the collated claim data is in condition for processing to initiate generation of payment. A claim processor submits the collated claim data to a payer, in response to successful validation by the pre-processor. A rules processor processes acquired claim data to identify a condition triggering application of a different set of rules for determining validity of an individual claim element.

Abstract: A system and method for calculating a pixel-shift vector that predicts the motion in dynamic image data and can be used to shift reference image data in order to generate a subtracted image with reduced motion artifacts. The pixel-shift vector is calculated based on displacement vectors that have been calculated based on past motion in the dynamic image data. One embodiment determines a virtual pixel-shift vector as a function of stored pixel-shift vectors that were previously determined as a function of a previously captured live frame. The virtual pixel-shift vector is a prediction of the location of the current live frame before the current live frame is captured. The mask frame is adjusted as a function of this virtual pixel-shift vector. The current live frame is then subtracted from the mask frame adjusted as a function of the virtual pixel-shift vector. The adjusted mask frame and the live frame will then overlap and the subtracted image will have reduced artifacts.

Abstract: A patient monitoring signal processing system adaptively varies medical signal data rate. The system uses an analog to digital converter for digitizing an analog cyclically varying input signal derived from a patient in response to a sampling clock input. The sampling clock determines frequency of analog to digital sampling of the analog input signal by the analog to digital converter. A detector detects first and second different signal portions within a cycle of the cyclically varying input signal.
