Compared with the benign prostate, the malignant prostate has higher peak systolic velocity, lower end diastolic velocity and resistance index. In these blood flow information, the end diastolic velocity is more consistent and significant. In this paper, an automatic prostate cancer detection using blood flow information in power Doppler ultrasonography is proposed. The prostate region was segmented...
To detect early prostate cancer, physicians usually apply the color Doppler ultrasound imaging to visualize prostate. Since color Doppler ultrasound imaging provides blood flow information, differentiating the malignancy from benign prostate diseases by inspecting Doppler spectrum is not difficult. However, it is hand-held, time-consuming, and only limited in a small and static region, which might...
