摘要： 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.

摘要： A method for continuous non-invasive hemodynamic state monitoring in a subject is provided. The method includes acquiring continuous ultrasound data via an ultrasound transducer attached to the subject. The method also includes estimating continuous arterial waveforms based upon the acquired ultrasound data. The method further includes deriving hemodynamic parameters for each cardiac cycle from the arterial waveforms. The method also 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. The method further includes continuously monitoring a hemodynamic state of the subject. The method further includes comparing a current state for one or more hemodynamic parameters of the subject to previously determined limits for the one or more hemodynamic parameters, and either outputting a trigger signal or alarm to a hemodynamic state monitor in an event that a change is detected in the current state of the one or more hemodynamic parameters or converting the arterial parameters into a continuous estimate of the arterial blood pressure in an event that a change is not detected.

摘要： 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.
