The method of drawing up the multi plane surface ultrasonic pictures of the object of three dimensions

摘要

Method in order to draw up the multi plane surface pictures of the capacity measurement territory of the object without acquiring measurement territory the data from the whole capacity. This method includes the fact that transducer is swept over the capacity measurement territory. At sampling position during sweep, as it is transmitted to in the capacity measurement territory, the surface where plural is scanned one or plural it crosses the ultrasonic beam from transducer. It is less than the number of beams the number of beams which are transmitted during sweep probably will be transmitted in order to scan measurement territory the whole capacity. It receives with transducer according to the beam which echo from the capacity measurement territory, is transmitted. From the echo which is received, the plane surface picture which corresponds to the plural surfaces is formed. At the time of a certain becoming deformed, echo from the capacity measurement territory which is less than the echo this method probably will receive measurement territory the whole capacity from scan, the fact that it receives with transducer, is included. As for this, as for this deformation, compilation of the plane surface picture which corresponds to the surface where the inside of the capacity measurement territory is buried is made possible. Because the margin which rubs only the limited plural surfaces of the territory, measurement territory from the whole capacity it scans, it draws up high picture quality and the plane surface picture of wide field of vision at actual time and it is possible to indicate. In addition, it is possible to do this method, by scanning transducer. This method is executed by the ultrasonic device.
