    摘要: The present invention relates to a method of improving a 3D ultrasound color Doppler image through a post-processing. A method of processing an ultrasound image, includes the following steps: a) recognizing a target object from an inputted ultrasound image based on an object recognition algorithm using connectivity of the target object; b) setting at least one object region by using the connectivity of the recognized target object; c) calculating a structure matrix by using voxel gradients of the object region; d) calculating a diffusion matrix from the structure matrix; and e) acquiring a processed ultrasound image by applying the diffusion matrix and the voxel gradients to the inputted ultrasound image.

    摘要: Provided is a device and method for calculating a lesion feature. The device includes a border discriminator configured to discriminate a border of a lesion on an image of an image signal, a border sharpness normalizer configured to normalize a border sharpness based on the border determined by the border discriminator and output the normalized border sharpness as a feature, and a vector generator configured to generate a vector having the feature outputted from the border discriminator as a component. Therefore, by using the lesion feature calculating device and method according to embodiments of the present invention, types of lesions on ultrasonic images are classified based on the borders of the lesions.
