Abstract
Breast cancer is one of the most common malignancies in women.Ultrasound diagnosis has become a common way of breast cancer detection because of its significant advantages such as cheap in price,convenient in operation,and harmless,etc.Its treatment depends on the early detection and diagnosis of tumors,to extract tumor edge is the premise of judging whether the tumor is benign or malignant.However,ultrasound images of breast tumors has their own limitations,such as low image contrast,speckle noise,missing edges,complex distribution of internal fine structure of the tumor,and in particular the malignant tumors have difficulties of the complex shapes.To solve these problems,we present in this paper a method,it uses fractional differential to enlarge image' s SNR,and then extracts tumor edge in combination with the regional growth.关键词
