The invention belongs to the field of ultrasonic medical technology, in particular to an ultrasonic spectrum offset parameter imaging method for determining cancellous bone microstructure. This method uses a single high-frequency ultrasound scan to measure the cancellous bone at each scan position to the cancellous bone vertical launch ultrasonic pulse wave; ultrasonic propagation by cancellous bone microstructure, the back scattering of ultrasonic signal received by the probe back the same; for each sweep signal receiving. Where are the signal processing, frequency offset parameter of the received signal and the transmit signal of the ultrasonic spectrum offset parameter matrix corresponding to the scanning area; the parameter matrix is mapped into the ultrasonic spectrum offset parameter image, pixel value and parameter value is proportional to. The present invention proposes methods for ultrasonic imaging using spectral offset parameters in cancellous bone of the back scattered signal, compared to the traditional cancellous bone imaging method based on transmission method, can better reflect the characteristics of the microstructure of cancellous bone.
【技術實現步驟摘要】
【技術保護點】
一種用于定征松質骨微結構的超聲頻譜偏移量參數成像方法，其特征在于具體步驟為： （１）超聲探頭在掃描系統控制下，掃描待測離體松質骨，在每個掃描位置，向離體松質骨垂直發射超聲脈沖波，超聲波的傳播受到松質骨微結構的作用，背向散射回來的超聲信號由同一超聲探頭接收； （２）對每一個掃描位置處接收的信號分別進行信號處理，提取接收信號與發射信號的頻譜偏移量參數，獲得對應于掃描區域的超聲頻譜偏移量參數矩陣； （３）把參數矩陣映射成超聲頻譜偏移量參數圖像，象素值與參數值成比例關系，完成超聲頻移量參數成像。
