Restoration of Ultrasound Images Using the 1st and 2nd Harmonic Signal

Original language description

The paper presents a new method for two-dimensional deconvolution of ultrasonic B-scan images. It is based on estimation of the point spread function from radiofrequency data by means of an improved homomorphic filtering scheme using two-dimensional phase unwrapping. The deconvolution is applied separately to images of the 1st and 2nd harmonic, coming from a broadband transducer. Based on the presented deconvolution technique, a new speckle suppression approach was proposed, where the enveloopes of thedeconvolved images of both harmonics are summed together to create a high-resolution image with suppressed speckle pattern. The method has been tested on clinical radiofrequency image data.

The deconvolution is applied separately to images of the 1st and 2nd harmonic, coming from a broadband transducer.

The method has been tested on clinical radiofrequency image data.
