摘要： An ultrasonic diagnostic imaging method and apparatus are presented which separates broadband linear and nonlinear echo signal components while simultaneously distinguishing the effects of motion. The inventive method maps ultrasonic echo signals in the r.f. (time) domain to Doppler shift frequencies in the Doppler domain in a way that depends upon the linearity of the echoes. The inventive method does this by analyzing the phase shifts between successive echoes. Apparatus is described in which a Doppler echo ensemble is acquired by a transmit sequence of cyclically phase-varying waveforms. When the echoes of the ensemble are combined during Doppler processing, the resulting Doppler spectrum is divided into separate regions, with odd harmonics (e.g., linear signal components) residing in one region and even harmonics (e.g., second harmonic signal components) residing in another region. In a preferred embodiment a Doppler wall filter is used to delineate a particular type of signal information for processing, such as tissue motion, harmonic contrast agent, or tissue harmonic imaging information.

摘要： An ultrasound system that utilizes a probe in conjunction with little or no specialized 3-D software/hardware to produce images having depth cues. A control unit uses the probe to produce multiple slices of data, wherein each slice has a plurality of lines of data points. The control unit oversees the combination of data points from matched lines across the slices so as to create an image on the display giving the illusion of depth.

摘要： A method of tracking position and velocity of objects' borders in two or three dimensional digital images, particularly in echographic images comprises the steps of: Acquiring a sequence of at least two consecutive ultrasound image frames of a moving tissue or a moving object which frames are timely separated by a certain time interval; Automatically or manually defining a certain number of reference points of a border of a moving tissue or object at least on a first image frame of the sequence of image frames acquired; Automatically tracking the border of the moving tissue or object in the at least one further following frame by determining the new position of the reference points of the border in at least one following image frame of the sequence of image frames by estimating the position of the said reference points in the said at least following image frame of the sequence of image frames on the basis of the ultrasound image data of the acquired sequence of image frames.
In the present invention the sequence of image frames acquired is a sequence of consecutive B-mode, grey scale ultrasound images; On a first frame a border line is drawn either manually or by means of an automatic border detection algorithm. The original trace of pixels of the manually or automatically drawn border line is followed in time, i.e. in at least one following image frame by searching the maximum likelihood of the trace of pixels in the following image frame with the trace of pixels in the first or timely previous image frame by analyzing the image pixels in the neighbourhood of the said trace of pixels.

摘要： Bei einem Verfahren bzw. bei einer Vorrichtung zur Generierung eines diagnostisch verwertbaren dreidimensionalen Bilddatensatzes mit einem Ultraschallgerät wird der Ultraschallkopf zur Erzeugung einer Sequenz einer Vielzahl von Ultraschallbildern frei über ein zu untersuchende Volumen geführt. Zur Bestimmung der Positions- und Orientierungsdaten der jeweiligen Bildebenen ist ein elektromagnetisches Sensorsystem vorgesehen, dessen Empfänger mit dem Ultraschallkopf verbunden ist. Die Ultraschallbilder werden bei der Datenakquisition zunächst in einem Bildverarbeitungssystem als Rohdaten mit dem Positions- und Orientierungsdaten abgelegt. Diese Rohdaten werden dann in einem dreidimensionalen Datensatz transformiert, der das zu untersuchende Volumen erfaßt und in welchem sämtliche Bilddaten oder Bildwerte auf ein neues gemeinsames Bezugssystem, vorzugsweise auf ein kartesisches Koordinatensystem bezogen sind.

摘要： A method and an apparatus for improving visualization of a needle-like instrument (54), such as a biopsy needle, inserted in a human body as described. The instrument is visualized by transmitting an ultrasound beam (56) toward the instrument (54) and then detecting the echo signals (58) using a linear array (2) of transducer elements (2'). The problem of ultrasound being reflected from a biopsy needle in a direction away from the transducer array (2) is solved by steering the transmitted ultrasound beam (56) to increase the angle at which the beam impinges upon the biopsy needle. Ideally the ultrasound beam is perpendicular to the biopsy needle. This increases the system's sensitivity to the needle because the reflection from the needle is directed closer to the transducer array. This can be accomplished using either the B mode or the color flow mode of an ultrasound imaging system.

摘要： An ultrasonic diagnostic imaging system and method are described by which a fundamental frequency signal is transmitted into the body and harmonic (nonlinear) echo returns are received from the transmission. The harmonic echo signals are Doppler processed and displayed. The harmonic Doppler signals may be displayed alone, or in combination with a fundamental frequency or harmonic grayscale image. In a preferred embodiment harmonic signals returned from moving tissue are segmented on an intensity or frequency basis and displayed. The inventive apparatus and method provide highly resolved ultrasonic images of moving tissue which are substantially unobscured by image clutter from structures or tissue in the near field.
