Abstract
A method and apparatus for generating an acoustic holographic image having a plurality of pulses with different characteristic parameters from each other. More particularly, a sequence contains a plurality of pulses which have different characteristic parameters from each other. An image is created for each sequence and the effect of each pulse in creating the image is varied based on the variation of the characteristic parameter for each pulse. A selectively enhanced acoustic image is thereby obtained.
Claims15
An apparatus comprising:
- a transducer assembly means for generating an acoustic signal to pass through an object;
- a lens means for receiving an acoustic signal after it has passed through the object;
- a holographic image detection means for receiving the acoustic signal after it has passed through the lens;
- and
- electronic control means for causing the transducer assembly means to generate a plurality of pulses spaced from each other in time, the plurality of pulses forming a sequence of pulses, each pulse having selected characteristic parameters within the pulse itself and a plurality of the pulses in the sequence having different characteristic parameters from other pulses in the same sequence.
A method generating an acoustic hologram comprising:
- generating a plurality of acoustic pulses;
- transmitting the plurality of acoustic pulses as a sequence of pulses through an object;
- varying a property of the acoustic pulse from one pulse to another pulse within the sequence of pulses passing through the object;
- receiving the sequence of pulses that have passed through the object;
- and
- creating an image for each pulse in the sequence that contains varying data based on the property of the pulse that was varied.
