Tissue signature tracking tranceiver

A method of processing imaging signals comprising the steps of:

• emitting a signal burst of a selected duration into a medium wherein the image-related information characteristics are degraded according to the medium characteristics;
• receiving energy from said medium according to said signal burst producing a received signal therefrom;
• filtering said received signal according to a filter having selectively adjusted high and low frequency response cutoff characteristics with said cutoff characteristics being adjusted in a same direction and
• detecting said filtered received signal, wherein
• filter response characteristic and said signal burst duration are selected to provide a detected filtered signal, said filter having a characteristic inverse to said medium related image degradation, to compensate for said degraded image characteristic.

An ultrasound tranceiver, comprising:

• transmitter means for producing a tone burst of selected duration into an acoustic medium having an image-degrading characteristic;
• receiver means for producing a received signal according to the reflected energy from said tone burst in said medium;
• means for filtering said received signal producing an output signal having a selected response characteristics;
• said filtering means having selectively adjusted high and low frequency response cutoff characteristics with said cutoff characteristics being adjusted in a same direction;
• and
• means for detecting said filter output signal, wherein
• at least one of a filter response characteristic and said tone burst duration are selected to provide a detected filter output signal having a characteristic inverse to said image-degrading characteristics to compensate for said acoustic medium image degrading characteristic.
