| Summary: | Contrast resolution and detail resolution are two important parameters in
ultrasound imaging. This paper presents a new method to enhance these parameters,
simultaneously. A parallel auxiliary beamformer has been employed whose weightings are
such that an estimation of the leaked signal through the main beamformer is obtained. Then
the output of main beamformer is modified according to the estimated leaked signal. The
efficiency of our adaptive method is demonstrated by applying it over an experimental data
set and provided an enhancement of about 22 percent in lateral resolution and 15-20 dB in
contrast resolution. This method also has the advantages of simplicity and possibility of real
time implementation. |
