1. A method of producing quantitative volume backscatter images from two dimensional B-scan ultrasonic images comprising the steps of:

  • transmitting acoustic pulses along many scan lines and producing beams of ultrasound to scan an object, receiving ultrasonic energy and generating received signals that are processed to provide B-scan image data which is displayed;

    correcting said B-scan image data to account for propagation effects that can alter backscatter intensity due to propagation from an image point to a transducer, and produce corrected data indicative of the volume backscatter coefficient; and

    displaying said corrected data as a gray scale volume backscatter image.
