Patent number: 9204857Abstract: A method for continuous non-invasive hemodynamic state monitoring in a subject. The method includes acquiring continuous ultrasound data, estimating continuous arterial waveforms based upon the acquired ultrasound data, and deriving hemodynamic parameters for each cardiac cycle from the arterial waveforms. The method further includes defining a current hemodynamic state of the subject by setting limits on one or more hemodynamic parameters based upon the variation of these parameters over an initial period of time, and continuously monitoring a hemodynamic state of the subject. Further, a current state for one or more hemodynamic parameters of the subject are compared to previously determined limits for the one or more hemodynamic parameters, and either an alarm is triggered in an event that a change is detected in the current state of the one or more hemodynamic parameters or the arterial parameters are converted into a continuous estimate of the arterial blood pressure.Type: GrantFiled: June 5, 2009Date of Patent: December 8, 2015Assignee: General Electric CompanyInventor: Aaron Mark Dentinger

Patent number: 7425199Abstract: Ultrasound is used to provide input data for a blood pressure estimation scheme. The use of transcutaneous ultrasound provides arterial lumen area and pulse wave velocity information. In addition, ultrasound measurements are taken in such a way that all the data describes a single, uniform arterial segment. Therefore a computed area relates only to the arterial blood volume present. Also, the measured pulse wave velocity is directly related to the mechanical properties of the segment of elastic tube (artery) for which the blood volume is being measured. In a patient monitoring application, the operator of the ultrasound device is eliminated through the use of software that automatically locates the artery in the ultrasound data, e.g., using known edge detection techniques. Autonomous operation of the ultrasound system allows it to report blood pressure and blood flow traces to the clinical users without those users having to interpret an ultrasound image or operate an ultrasound imaging device.Type: GrantFiled: September 23, 2004Date of Patent: September 16, 2008Assignee: General Electric CompanyInventors: Ralph Thomas Hoctor, Kai Erik Thomenius, Aaron Mark Dentinger

Patent number: 7068715Abstract: An ultra-wideband (UWB) communications system combines the techniques of a transmitted reference (TR) and a multiple access scheme called delay hopping (DH). Combining these two techniques using UWB signaling using a continuous noise transmitted waveform avoids the synchronization difficulties associated with conventional approaches. This TR technique is combined with the DH multiple access technique to create a UWB communications scheme that has a greater multiple access capacity than does the UWB TR technique by itself.Type: GrantFiled: October 10, 2001Date of Patent: June 27, 2006Assignee: Genral Electric CompanyInventors: Ralph Thomas Hoctor, David Michael Davenport, Aaron Mark Dentinger, Nick Andrew VanStralen, Harold Woodruff Tomlinson, Jr., Kenneth Brakeley Welles, II, John Erik Hershey

Patent number: 6166384Abstract: A method for generating a high resolution image in a radiation imaging system which produces multiple exposure signals from a movable detector array is disclosed. The image data signals or image acquisition signals generated from the image detector assembly of the image radiation system during an imaging cycle are passed through a finite impulse response filter having a combined frequency response comprised of an inverse filter frequency response portion and a noise regularization frequency response portion such that the noise regularization decrease the frequency response of the filter as the frequency of the data signals increase thereby effectively preventing blurring of the image produced from the image data signals.Type: GrantFiled: November 6, 1998Date of Patent: December 26, 2000Assignee: General Electric CompanyInventors: Aaron Mark Dentinger, Sung Su Han, Sameh Mahmoud Sowelam
