摘要：
The present invention provides an acceleration and enhancement methods for ultrasound scatterer structure visualization. The method includes: obtaining an ultrasonic image, calculating all values of the ultrasonic signal in mth regions centered on a nth signal point to obtain a plurality of original statistical values anxm, obtaining mth statistical values from an average value of plurality of original statistical values in the same region, calculating mth weighting values according to the statistical values by different average weighting formulas, multiplying the weighting values with the original statistical values corresponding to each value of the nth signal points, summing up to obtain an nth ultrasound scatterer value, and displaying an ultrasound scatterer structure image according to the ultrasound scatterer values. The present invention combined interpolation method can reduce the computation time and retain the 80% accuracy.本發明提供一種加速與強化聲波散射影像視覺化之方法及系統,成像方法包含:以一第n超音波訊號點為中心,統計在m個不同計算範圍內超音波訊號點之數值,取得複數個原始統計參數值anxm;分別加總相同計算範圍內原始統計參數值後再平均,取得m組統計參數;結合不同權重平均技術計算m個權重值,每一權重值分別乘以對應該些第n超音波訊號點之原始統計參數值再加總,取得該第n聲波散射數值,以顯示出聲波散射統計影像圖,可強化影像解析度和平滑度,提升影像品質。本發明亦可結合內插法,可節省運算時間,亦能保持八成以上之準確率。S100‧‧‧聲波散射訊號之成像方法S10~S60‧‧‧步驟
