Abstract: An ultrasonic diagnostic imaging system is provided in which a portion of an ultrasonic image can be selected for enlarged display as a "zoom" image. When the image portion is displayed in its enlarged format, the bandwidth of a filter in the ultrasonic information path is extended to increase the information content of the image portion when displayed in its enlarged format. The bandwidth is continuously optimized to maximize information content in consideration of the characteristics of the display while preventing the generation of scintillation artifacts caused by attempts to display information of an excessive bandwidth.

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.

Abstract: A multiplane TEE probe is provided in which rotation of the ultrasonic transducer is motor controlled. The motor is controlled to rotate the transducer either clockwise or counterclockwise, and at either a high rotational speed or a low rotational speed. The motor is also automatically controlled to drive the transducer to a predetermined home position. The transducer tip of the probe is detachably connected to the gastroscope tube. An aluminum sheet is embedded in the acoustic lens in front of the transducer to dissipate heat which accumulates in the lens. The gastroscope tube includes an articulating section formed of a plurality of matching cylindrical links which form alternating pivot axes from one link to the next. The pivot range of each link with respect to an adjoining link is controlled by opposing limit stops orthogonally located with respect to the pivot points of the links. Preferably the limit stops are formed by a plurality of opposing and meshing fingers to provide the articulating section with high torsional stability. The articulating section is controlled from the handle of the probe, with the articulation limit stops located in the handle. The articulating section may be locked in a given bent position, but the lock will be overcome by the force of the esophagus against the transducer tip if the probe is withdrawn in a locked and bent position. When the articulating section is locked an indication signal is displayed on the handle of the probe and on the display of the ultrasound system.

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 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 ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure without disrupting control of the scanhead. Means (36) are provided on the external control unit (16) of the scanhead for unambiguously selecting the orientation of the plane which is imaged by the transducers (E1L..E48T) at the end of the probe (12) of the scanhead. In one embodiment, a rocker switch (36) is provided on the underside of the control unit, and a lighted indicator (40) is provided on top of the control unit. When the physician desires to change the image plane, the rocker switch is rolled forward to select the transducer elements (E1L..E48L; E1T..E48T) of the probe which are configured for scanning in the desired image plane. As the rocker switch is moved, the lighted indicator (40) on the top of the control unit provides a visual display pattern aligned either longitudinally (40b, 40c) or transversely (40a, 40b) with respect to the axis of the probe. Thus, the physician can change scanning planes without moving his hand from the control unit, and the unit constantly provides an indication of the orientation of the selected plane.

Abstract: The scanhead (10) uses a shaft mounted, oscillating rotor (22) driven by a shaft mounted motor (14). Energy storage and repulsive means, provided by magnetic "bumpers" (56, 58) helps to reverse the direction of motion of the rotor (22) at the end of the scan angle (30) of an ultrasonic transducer (26) which is mounted on said rotor (22). The oscillating scanhead (10) has the advantage of being less expensive to produce in that only a single transducer (26) is required, thereby avoiding the problems associated with matching transducers and aligning them on the same axis.
