The method: detects an ... 10/26/06 - 20060241459 - Automatic signal-optimizing transducer assembly for blood flow measurement The invention uses a transducer and ultrasound system to form and direct ultrasound beams through the blood stream that will detect the Doppler shift in frequency between the beams and the return echo off the blood. The transducer can be secured onto the surface of the patient's skin with a ... 08/17/06 - 20060184032 - Ultrasonic diagnosis apparatus An ultrasonic diagnosis apparatus comprises an ultrasound probe, a transmitter (including a transmitting pulse generator and a transmitting beamformer), a receiver (including a preamplifier and a receiving beamformer), a CFM processor (including a moving-element signal extractor and a velocity corrector), a tomographic image processor, and a display unit. The apparatus ... 08/03/06 - 20060173337 - Intravascular ultrasound probing device The present invention provides an intravascular ultrasound probing device using Doppler effect. The intravascular ultrasound probing device comprises a first tube, a first ultrasound probe head positioned in the first tube, a second ultrasound probe head positioned in the first tube and an separating member positioned between the first ultrasound ... 06/08/06 - 20060122512 - Ultrasonic diagnostic stystem and system and method for ultrasonic imaging The ultrasonic diagnostic system estimates a desired time phase or one cycle period of a moving region (e.g., a heart) that repeats contraction and relaxation cyclically and which can be specified by a presystole, an end systole, a prediastole, an end diastole, and other clinical characteristics for one cycle of ... 06/08/06 - 20060122511 - Ultrasonic doppler bloodstream measurement device The present invention is for an ultrasonic Doppler blood flow measurement device with which high-speed computation is possible, even when a memory having the characteristic of different read/write speeds in the row direction and the column direction is used for the buffer memory when computing blood flow information, without being ... 05/04/06 - 20060094964 - Method and apparatus for non-invasive continuous monitoring of cerebrovascular autoregulation state A non-invasive method for continuous real-time monitoring of cerebrovascular blood flow autoregulation state includes simultaneous non-invasive monitoring of intracranial blood volume respiratory waves and lung volume respiratory waves, real-time decomposition of intracranial blood volume respiratory waves and lung volume respiratory waves into narrowband sinewave first harmonic components, determination therefrom of ... 05/04/06 - 20060094963 - Minimum arc velocity interpolation for three-dimensional ultrasound imaging Minimum arc interpolation is performed on velocity information distributed in three dimensions. By using complex representations of the velocity information, the interpolation may more accurately represent the angle or velocity for spatial conversion. Tri-linearly interpolating velocity information converts the information representing a three-dimensional volume to a reconstruction grid. The interpolation ... 03/09/06 - 20060052705 - Ultrasound diagnostic apparatus and ultrasound signal analyzing method In quantitative analysis using blood flow velocity measurement and the like, whether to select the forward direction or reverse direction is determined in accordance with the positional relationship between a baseline for controlling the display scale of a Doppler waveform and a reference line which can be arbitrarily set by ... 02/02/06 - 20060025688 - Blood flow visualizing diagnostic apparatus A blood flow visualizing diagnostic apparatus characterized by having an ultrasonic measurement unit 120 which emits an ultrasonic beam toward a blood vessel inside a human body to receive the reflected ultrasonic signal, an analysis processing unit 220 which obtains a blood vessel shape and a blood flow velocity in ... 12/01/05 - 20050267370 - Velocity estimation apparatus and method A velocity estimation apparatus and method for a communication system including a transmitter for transmitting signals through wireless channels and a receiver for receiving the signals and restoring data. The apparatus includes a pilot signal detector for detecting a pilot signal from a received signal, a maximum Doppler frequency estimator ... 11/17/05 - 20050256408 - Method and apparatus for improving the accuracy with which the speed of a fluid is measured The present invention relates to a method and associated apparatus for improving the accuracy with which the speed of a fluid, such as a liquid, in particular blood flowing in a duct, such as a blood vessel, in particular the aorta, is measured by means of a signal emitted by ... 08/04/05 - 20050171432 - Detecting, assessing, and diagnosing sleep apnea The present invention comprises methods for detecting, assessing, diagnosing, and pre-diagnosing sleep apnea, and for assessing the efficacy of a treatment for sleep apnea. Methods for the detection, assessment, diagnosis and pre-diagnosis (screening) of sleep apnea and the assessment of a treatment for sleep apnea according to the present invention ... 07/07/05 - 20050148876 - Individual identification device In order to provide an individual identification device for enabling good blood-vessel imaging even in a noncontact way and using an identifying method suitable for noncontact imaging, the device comprises an imaging device for imaging blood vessels of a hand of the user in a noncontact way including a position/direction/shape ... ### FreshPatents.com Support |
