    摘要： The present invention relates a method and an apparatus for enhancing ultrasound image quality through a post-processing. A method for enhancing an image quality of a two-dimensional (2D) ultrasound image, comprises the steps of: a) decomposing the 2D ultrasound image into a plurality of images having a multi-resolution by N levels, wherein N is a positive integer; b) determining characteristics of each pixel in the decomposed image; c) performing an enhancement process for the decomposed image based on the pixel characteristics; d) performing 1st-level composition for the decomposed image; and e) repeatedly performing steps b) to d) until a size of the composed image is identical to that of the 2D ultrasound image.

    摘要： Embodiments for registering a CT image onto ultrasound images are disclosed. At a preoperative stage, a plurality of first ultrasound images are formed during a respiratory cycle and a CT image is obtained at the maximum inspiration. The CT image is registered onto each of the ultrasound images to thereby form ultrasound-CT registered images. The ultrasound-CT registered images may be stored in the storage unit. Subsequently, at an intraoperative stage, a plurality of second ultrasound images may be sequentially formed in real time. Similarities may be measured between the first ultrasound images and the second ultrasound images, and the ultrasound-CT registered images, each corresponding to each of the first ultrasound images having highest similarity to the second ultrasound image may be retrieved. The retrieved ultrasound image and the second ultrasound image may be displayed at the same time.
