    摘要: An ultrasonic probe is moved to scan a volumetric region of the body. As it is moved, targets within the region are interrogated from multiple look directions. The echo data from the multiple look directions are compounded to form spatially compounded image data, which is processed for display in a three dimensional display format.

    摘要: An ultrasonic diagnostic imaging system is are described in which the component ultrasonic images which are to be spatially compounded are corrected for misregistration prior to compounding. The component images may be registered to a reference image or registered to form intermediate compound images which are then registered and compounded. The misregistration may be sensed by calculating a similarity or difference metric for a region of interest of the image frames being registered, or on the basis of reference lines acquired for the purpose of registering images.

    摘要: An ultrasonic diagnostic imaging system is provided which scans an image region to receive a plurality of spatially arranged lines of ultrasonic image information signals. These ultrasonic line information signals are used in an interpolater to interpolate one or more lines which are spatially interlineated between each pair of spatially adjoining received lines. These interpolated lines are produced using either the received RF or demodulated IF ultrasonic image information signals. The interpolated lines are produced prior to scan conversion, and preferably prior to nonlinear processing such as detection or log compression to reduce spatial aliasing artifacts. In one preferred embodiment the interpolater comprises a transversal filter of four taps which is responsive to received line information signals from a common range or depth. In a second embodiment the interpolater is adaptively responsive to motion to select samples for interpolation which would be spatially at the same range in the absence of motional effects.

    摘要: An ultrasonic transducer is provided for producing two-dimensional projection images of the interior of the body. The transducer may comprise an array of elements, acuated to produce scanning beams which are focused in the azimuthal direction and divergent in the elevation direction. The elements will, when actuated, emit fan-shaped beams which will insonify a volumetric region in front of the transducer. Echoes returning from structures within the volumetric region are acoustically integrated and projected onto a plane within the region. An image display of this plane will represent a two-dimensional projection of the volumetric region.

    摘要: The invention relates to an ultrasound imaging system for forming an echographic image of a medium, which system includes a set [REC] of transducer elements [EL] which are operative in a transmission mode and in a reception mode for ultrasound waves, construction means [REB] for constructing echographic signals on the basis of signals [S[1] . . . S[N]] received on the transducer elements [EL], display means [DIS] which are coupled to the construction means [REB] in order to display an image of the medium formed by means of the echographic signals. The construction means [REB] are such that in so-called exclusion zones, in which a coherent reflector is detected and which are determined by determination means [DET], the reception delays [D] are estimated in a manner [INT] other than that [CORR] used for the other zones. The calculation [CAL] of echographic signals is then carried out on the basis of the estimated delays [D[Z],Di[Z}}. The invention enables a correction of phase aberrations and nevertheless offers an excellent lateral resolution, notably in the case of point coherent reflectors.
