基于电阻抗扫描成像的乳腺癌检测方法
Method for detecting breast cancer by eletrical impedance scanning
摘要
Abstract
Abnormal energy indicator (AEI) calculated by complete parameters extraction algorithm (CPEA) is proposed to decrease the false positive rate of electrical impedance scanning. CPEA includes two parts: the modeling of the forward problem and the parameters extraction process. The parameters of the cancerous lesion within breast are extracted by CPEA which are then used to calculate the AEI for detection of breast cancer. Compared with the conventional detection method of image interpretation by experienced clinicians, using the AEI to detect breast cancer can achieve higher sensitivity, specificity and accuracy. In addition, employing the AEI can obtain excellent sensitivity and specificity compared with CAD (computer assisted diagnosis) algorithms, such as the HEDA (homologous electrical difference analysis) and the P algorithm. Experimental results suggest that AEI can be used in detecting breast cancer effectively, with a better detection performance (sensitivity as 88. 5% , specificity as 89. 1% and accuracy as 88. 9% ).关键词
