Imaging of a region in a scattering medium

A method for imaging a region in a scattering medium, comprising:

• modulating a beam of energy passing through a region of a scattering medium by at least two ultrasonic energy waves having different spatial relationships with said beam of energy so as to form at least two different modulated energy patterns;
• and
• detecting and processing said modulated energy patterns to form an image of said region, wherein said region of said scattering medium is disposed between first and second opposed surfaces thereof, and said modulating comprises propagating ultrasonic pulses through said scattering medium in a direction substantially parallel to each of said first and second surfaces;
• and further comprising projecting onto the second surface of said scattering medium images of the modulated beams exiting said scattering medium so as to form said modulated energy patterns, each modulated energy pattern corresponding to a different view of said scattering medium;
• detecting the modulated energy patterns projected on said second surface;
• time resolving the detected modulated energy patterns;
• and
• correlating electrical signal representations of the different views of said scattering medium to generate electrical signal representations of respective images of portions of said scattering medium through which said ultrasonic pulses travel;
• and
• analyzing said images to find a statistical distribution of an image vector texture.
