Claim 14:
15. A method of detecting one or more objects using ultrasound imaging technology that images by producing from an ultrasound system an ultrasound wave having a frequency with a corresponding ultrasound wavelength, comprising:
placing an object capable of at least partially reflecting ultrasound waves into a substance that at least partially conducts ultrasound waves, the object having a first state at a first state position;
moving the object to a second state at a second state position that is different than the first state position;
allowing ultrasound waves from the ultrasound system to be reflected from the object at the first state position and the second state position; and
creating a first speckle pattern at the first state position and a second speckle pattern at the second state position, wherein a difference between first speckle pattern and the second speckle pattern determines a location of the object.
