Abstract

Static ultrasound elastography is a technique that provides information on local tissue elasticity. However, it is known that the quality of the image in static ultrasound breast elastography is significantly degraded by speckle noise, artifacts and poor information accuracy. In this context, the implementation of an optimum technique for treating the elastogram is then indispensable. In this article, the study focuses on the research for a strategy that reduces the propagation of speckle noise and artifact; biophysical parametric tools have been introduced to improve the quality of breast elastogram. The study was performed on 40 patients with malignant tumors. Accurate and excellent breast elastogram was observed in proposed method results. By configuring the rate of probe movement in the range from 90 to 120 cycles/ min, the dynamic elasticity in the scale from 1 to 9, the persistence at level 8, smoothing at level 4, and rejection at level 3, we obtain a higher performance for breast elastogram, it gives a better values in term of Standard Deviation (SD), better Contrast to Noise Ratio (CNR) and better Signal to Noise Ratio (SNR). The results of the proposed model are encouraging, allowing quick and reliable estimation.
