| Abstract(in English) | The purpose is to remove the speckle noise and to emphasize the boundary of a tumor by filtering based on the intensity difference in the medical ultrasound images. The proposed method is evaluated using numerical phantom simulating ultrasound B-mode images, and the effect is confirmed by applying to medical ultrasound images. Ultrasound image diagnosis is a medical diagnosis that can obtain a tumor and states of intrabody without damaging human body. The equipment is smaller than other equipments such as X-rays CT(Computed Tomography) and MRI(Magnetic Resonance Imaging)and an US diagnosis is convenient by the bed side. However, ultrasound images have a lot of speckle noises and the spatial resolution is low. Therefore, some important features such as tissue boundaries and small tumors may be overlooked. CNN(cellar neural network) for speckle reduction and the edge enhancement are proposed in this paper. It could be obtained more detail images recognition compared with the former researchers in this study. |
