ABSTRACT:
Obstructions in a blood vessel are identified and displayed by determining changes in textural patterns based on the ultrasonic waves reflected from the blood vessel. The textural pattern from stationary scatterers, such as found in a clot, remains essentially constant, whereas the texture pattern for moving scatterers such as flowing blood cells is ever changing. By determining and imaging the variations in textural pattern of the reflected ultrasonic waves the identification of obstructions in the vessel is realized.
