Abstract: An ultrasonic diagnostic imaging system is provided for scanning with a linear transducer array and displaying an image area which is truncated with respect to a conventional triangular image sector to take the form of a trapezoid. Uniformity of image resolution and ease of signal processing enhancement is provided by transmitting adjacent ultrasonic beams at equal angular increments over the sector area. The ultrasonic beams transmitted are focused around predetermined transmit focal points and the transmit aperture employed for each transmission is determined by a transducer sensitivity criterion applied to the focal point. Means are provided for delaying signal components received from the beam directions so that the sum of the components will form a coherent echo signal. Means are provided for dynamically focusing received signal components by dynamically focusing received signal components by dynamically varying the sampling frequencies of laterally disposed signal components, and the receive aperture is dynamically varied in correspondence with the number of array elements which satisfy a sensitivity criterion at different depths of field.

Abstract: An array of ultrasonic transducer elements receives signals to form beams simultaneously from a plurality of beam directions. The echo signals received by each transducer element are sampled in response to two or more interleaved sampling signal sequences, each of which is timed to begin at the initial time of arrival of echo signals from a unique spatial line. Each sampling signal sequence thereby produces signal samples associated with a given line. The stream of interleaved signal samples from each transducer element are separated in correspondence with each sampling signal sequence, and signal samples from corresponding separated sequences from the transducer elements are summed to form coherent signals corresponding to spatially separate ultrasonic beams.

Abstract: An ultrasonic imaging system is disclosed which produces a sequence of images of planes of a subject including both image and spatial positional information of the image plane. In one embodiment the positional information is developed from a plurality of accelerometers located within a scanhead. The second integrals of the acceleration signals are used to determine positional information of the image plane. In a second embodiment a tranmitter transmits a magnetic field and a receiver attached to the scanhead detects the position of the scanhead in relation to the transmitted magnetic field. Spatially related images are displayed by displaying one image plane in the plane of the display and a second image plane projected in relation thereto. Either of the displayed planes may be displayed in outline form, and the outline may be modulated to depict depth.
