  • Patent number: 7458936
    Abstract: A system and method for providing decision support to a physician during a medical examination is disclosed. Data is received from a sensor representing a particular medical measurement. The received data includes image data. The received data and context data is analyzed with respect to one or more sets of training models. Probability values for the particular medical measurement and other measurements to be taken are derived based on the analysis and based on identified classes. The received image data is compared with training images. Distance values are determined between the received image data and the training images, and the training images are associated with the identified classes. Absolute value feature sensitivity scores are derived for the particular medical measurement and other measurements to be taken based on the analysis. The probability values, distance values and absolute value feature sensitivity scores are outputted to the user.

  • Patent number: 7395109
    Abstract: Heart monitor signals indicating a patient's heart characteristics are amplified without affecting the signal characteristics. The amplified heart monitor signals with atypical characteristics are transmitted to a pattern recognition platform which stores the patient's previously provided signals with atypical characteristics. The patient's present and previously provided signals with atypical characteristics are compared to select the previously provided signals with characteristics closest to those of the presently provided signals. Database signals identifying different types of heart problems in third parties and having characteristics closest to the patient's selected atypical signals are chosen. Dependent upon the severity of the patient's heart problems identified by the chosen database signals, the monitor transmits the chosen database signals to an individual one of the patient's doctor, the patient's hospital and an emergency care facility.

  • Patent number: 7351203
    Abstract: Patients are evaluated in terms of various physiological parameters such as hemodynamic parameters. Covariate information indicative of the patient's individual characteristics may also be determined. A state variable indicative of the patient's characteristics is determined. This state variable is used to compare the patient to other patients in the database. The other patients in the database are evaluated in terms of similar parameters and their probability of survival as well as different treatments and the probability of survival based on those different treatments. The patient may be simply evaluated based on the database or a proper course of treatments may be determined based on the database.

  • Patent number: 7315755
    Abstract: The present invention aims at permitting numerous user terminals to share protocols as common resources. A vendor terminal or user terminal registers a pair of a protocol and a medical image, which is produced during scanning performed according to the protocol, by recording data in a protocol/medical image database included in a protocol management server. The user terminal acquires a medical image from the protocol management server over a network, and displays it on a display device. Moreover, the user terminal downloads a required protocol from the protocol management server and sets it in a medical diagnostic imaging system.

  • Patent number: 6810391
    Abstract: a System for calculating and emitting analytical data, particularly medically relevant analytical data, has a computer with an evaluation unit for analyzing information entered by the system user and for generating the analytical data, and an output medium provided at the user side. The evaluation unit is configured for interrogating and accepting information that can be entered at the user side such that the information can be entered autonomously by the user based on a number of inquiries which are predefined at the system side, and which can be selected with reference to each response, and which can be made available as an output to user via the output medium. The evaluation unit is configured for controlling an interactive information capture such that, depending on the running information compilation, specific inquiries can be formulated and shown to the user.

  • Publication number: 20040210124
    Abstract: The present invention proposes a method for calculating, presenting, and combining probabilistic functional maps (PFMs) of the human brain representing the probability of structures existing. The method comprises three major steps: reading of data containing the coordinates of contacts, calculating the PFMs, and presenting the PFMs. The data can be read from a file in text or binary format or from a database as local or remote client. The PFM calculation comprises the following steps: forming 3D models of contacts, normalizing the contact models, voxelizing the contact models, calculating an atlas function, and calculating the PFM. The PFM can be presented alone or along with anatomical atlases. Both 3D and 2D interfaces can be used for presentation. The proposed method also includes different ways of combining the contact data and/or existing PFMs from multiple sources. This mechanism is the basis of an internet portal for stereotactic and functional neurosurgery.

  • Patent number: 6684188
    Abstract: A computer implemented system for the production of medical records, legal documents and other frequently produced semi-technical documents. This is accomplished by generating an intelligent computer-guided interview and the use of serialized scriptable objects. Major program elements include a knowledge base text file, a parse engine, and an execution module. The knowledge base uses a unique rule syntax. The parse engine converts the textual knowledge base file to a compiled binary representation which can then be interpreted by the execution module. The execution module leads the user through the interview by generating a series of questions and presents possible answers in the form of pick lists. The data is recorded with a computer pen and collated into a document file. This file is coded in binary format and can be written to and recalled from disk. If the file is recalled from disk the user can continue to answer questions or change answers previously given.

  • Patent number: 6575905
    Abstract: A real-time glucose estimator uses a linearized Kalman filter to determine a best estimate of glucose level in real time. The real-time glucose estimator receives at least one measurement corresponding to glucose level. The measurement can be obtained with one or more sensors and is provided to the linearized Kalman filter in real time. The linearized Kalman filter has dynamic models and executes a recursive routine to determine the best estimate of glucose level based upon the measurement. Additional information can be provided to the linearized Kalman filter for initialization, configuration, and the like. Outputs of the linearized Kalman filter can be provided to a patient health monitor for display or for statistical testing to determine status of the real-time glucose estimator. The real-time glucose estimator can be implemented using a software algorithm.
