Patent number: 8300907Abstract: An object of the present invention is to easily maintain the couch positioning accuracy and reduce the couch positioning time while resolving the complexity of input operations by the operator at the time of couch positioning. To accomplish the above object, calculation points are set to a CT image at the time of treatment planning, and the 3D coordinates of the set calculation point are set to a DRR image. When a couch positioning unit 115 loads the DRR image from an image server 109, it reads the coordinates of calculation points set to the DRR image and displays them on the monitor 116 together with the DRR image. Further, when DR image data is loaded into the couch positioning unit 115, the DR image is displayed on the monitor 116 and calculation points set to the DRR image are set also to the DR image.Type: GrantFiled: January 23, 2008Date of Patent: October 30, 2012Assignee: Hitachi, Ltd.Inventors: Yoshihiko Nagamine, Toshie Sasaki, Takao Kidani

Patent number: 8292832Abstract: A health activity plan may be prescribed for an individual comprising a set of health activity instances (e.g., physical therapy exercises, an exercise regimen, or a wound management program.) The performed health activity instances of the individual may be tracked by a device, and may be presented to a user of the device in correlation with the health activity plan (e.g., to demonstrate compliance of the individual with the health activity plan.) The health activity information may be presented using a set of icons that depict the health activity information, which may improve an easier understanding and a more consistent communication of health activity information among the individual and healthcare providers.Type: GrantFiled: July 27, 2009Date of Patent: October 23, 2012Inventor: Anthony Vallone

Patent number: 8231540Abstract: A system and method for evaluating a patient status from sampled physiometry for use in respiratory insufficiency management and heart failure assessment is presented. Physiological measures are stored and include direct measures regularly recorded on a substantially continuous basis by a medical device for a patient or measures derived from the direct measures. The physiological measures are sampled, which each relate to a same type of physiometry, and those of the physiological measures, which each relate to a different type of physiometry. A status is determined through analysis of those sampled physiological measures assembled from a plurality of recordation points. The sampled physiological measures are evaluated. Any trends are identified and include one of a status quo and a change, which might affect cardiac performance or respiratory performance.Type: GrantFiled: August 20, 2007Date of Patent: July 31, 2012Assignee: Cardiac Pacemakers, Inc.Inventor: Gust H.

Patent number: 8231539Abstract: An automated patient care system and method for diagnosing and monitoring respiratory insufficiency is presented. A plurality of monitoring sets are stored into a database. Each monitoring set includes recorded measures, which each relate to patient information and contain medical device measures recorded on a substantially continuous basis or derived measures calculable therefrom. The monitoring sets are retrieved from the database. A set of indicator thresholds are defined. Each indicator threshold corresponds to a quantifiable physiological measure of a pathophysiology indicative of respiratory insufficiency. A respiratory insufficiency finding is diagnosed. A change in patient status is determined by comparing at least one recorded measure to at least one other recorded measure with both recorded measures relating to the same type of patient information. Each patient status change is compared to the indicator threshold corresponding to the same type of patient information as the recorded measures.Type: GrantFiled: July 17, 2007Date of Patent: July 31, 2012Assignee: Cardiac Pacemakers, Inc.Inventor: Gust H.

Patent number: 8195280Abstract: A method of classifying arrhythmias using scatter plot analysis to define a measure of variability of a cardiac rhythm parameter such as for example, without limitation, R-R interval, A-A interval, and the slope of a portion of a cardiac signal, is disclosed. The variability measurement is derived from a scatter plot of a cardiac rhythm parameter, employing a region counting technique that quantifies the variability of the cardiac rhythm parameter while minimizing the computational complexity. The method may be employed by an implantable medical device or system, such as an implantable pacemaker or cardioverter defibrillator, or by an external device or system, such as a programmer or computer. The variability measurement may be correlated with other device or system information to differentiate between atrial flutter and atrial fibrillation, for example. The variability information may also be used by the device or system to select an appropriate therapy for a patient.Type: GrantFiled: December 31, 2009Date of Patent: June 5, 2012Assignee: Medtronic, Inc.Inventors: Peter M.

Patent number: 8194948Abstract: A reference point-designating section 18b designates two reference points on a measurement object. A reference curve-calculating section 18c calculates a reference curve calculated by approximating an outline of the measurement object based on the reference points. A loss-composing point-calculating section 18d calculates loss-composing points constituting a loss outline formed on the measurement object based on the reference points and the reference curve. A loss size-calculating section 18f measures loss size based on the loss-composing points. Designating two reference points enables loss size measurement, thereby reducing complex operation and improving operability.Type: GrantFiled: January 29, 2008Date of Patent: June 5, 2012Assignee: Olympus CorporationInventor: Fumio Hori
