Abstract
A scanning unit comprises two sound transducer heads for projecting sound beams, which are caused to scan a common section plane. Echo signals are derived from the echoes generated in response to said sound beams and are displayed on a fluorescent screen at locations which are geometrically coordinated with the locations at which the corresponding echoes have originated. The sound beam from one sound transducer head scans the section surface in an area which is generally rectangular or has only slightly divergent side edges. The sound beam from the other sound transducer head scans the section surface in an area which has greatly divergent side edges. These areas of the section surface are displayed on different areas of the fluorescent screen. Such scanning unit can be adapted to object of various shapes.
Claims20
Ultrasonic section surface examination equipment, comprising
- a scanning unit which defines a plurality of sound paths and comprises first and second sound transducer heads, each of which comprises at least one sound transducer that is operable to project a sound beam along an associated one of said sound paths into a section surface of an object to be examined and to receive echo signals generated in said section surface in response to said sound beam and to derive echo signals from the echoes thus received,
- scanning mechanism means for mechanically operating said scanning unit so as to move said sound paths transversely to themselves in said section surface in coordinated movements whereby the sound beam projected from a sound transducer of said first sound transducer head is caused to scan said section surface in a first section surface area having substantially divergent side edges and the sound beam projected from a sound transducer of said second sound transducer head is caused to scan said section surface in a second section surface area which is adjacent to said first area and has side edges which are less divergent than those of said first area, and
- display means comprising a fluorescent screen and operable to display said echoes on said fluorescent screen in response to echo signals from said sound transducer of said first sound transducer head in a first screen area at locations which are geometrically coordinated with the locations at which the corresponding echoes have originated in said first section surface area and, at the same time, in response to echo signals from said sound transducer of said second sound transducer head in a second screen area at locations which are geometrically coordinated with the locations at which the corresponding echoes have originated in said second section surface area.
