摘要： An ultrasound imaging system includes a scan conversion process for converting ultrasound data into a standard display format conversion and can be performed on a personal computer by programming the computer to convert data from polar coordinates to cartesian coordinates suitable for display on a computer monitor. The data is provided from scan head enclosure that houses an array of ultrasonic transducers and the circuitry associated therewith, including pulse synchronizer circuitry used in the transmit mode for transmission of ultrasonic pulses and beam forming circuitry used in the receive mode to dynamically focus reflected ultrasonic signals returning from the region of interest being imaged.

摘要： An ultrasonic imaging system (10) includes an ultrasonic transducer (16) having an image data array (18) and a tracking array (20) at each end of the image data array (18). The tracking arrays (20, 22) are oriented traversely to the image data array (18). Images from the image data array (18) are used to reconstruct a three-dimensional representation of the target. The relative movement between respective frames of the image data is automatically estimated by a motion estimator (38) based on frames of data from the tracking arrays (20, 22). As the transducer (16) is rotated about the azimuthal axis of the image data array (18), features of the target remain within the image planes of the tracking arrays (20, 22). Movements of these features in the image planes of the tracking arrays are used to estimate motion as required for the three-dimensional reconstruction. Similar techniques estimate motion within the plane of an image to create an extended field of view.

摘要： Disclosure is a fan-shape scanning flaw detecting apparatus which comprises: a prove (1) provided with an ultrasonic wave transmitting-and-receiving array transducer (2) arranged along a circular arc and an acoustic lens (3) for converging and converting an ultrasonic beam (2a) transmitted/received by the array transducer (2) into a substantially parallel beam (3a); a scanning function section (6, 7 and 8) for sequentially switching the transmitting and receiving operation of a group of operative transducer elements of the array transducer (2) so as to make the ultrasonic beam (3a) perform fan-shape scanning; a picturizing processor section (11) for forming a sectional image of an object (4) to be examined on the basis of an echo signal (7a) obtained from the object to be examined; a display section (12) for displaying the sectional image; and a position detecting section (14) for detecting a position ( x ) where the ultrasonic beam (3a) is incident to the object to be examined when the prove is made to run along a surface of the object to be examined so as to perform the flaw detecting operation. In the apparatus, image information of a sectional image of the object to be examined under a running path of the prove is formed by the picturizing processor section on the basis of information representing the position ( x ) of the ultrasonic beam (3a) incident to the object to be examined obtained from the position detecting section and information representing a position and reflection intensity of a reflection source (43) inside the object to be examined obtained on the basis of a reflection signal of a transmitted ultrasonic pulse reflected by the reflection source, and the sectional image information is then read and displayed by the display section.
