    摘要： There is disclosed an embodiment for extracting anatomical features from a 3-dimensional B-mode ultrasound liver image for image registration. A system extracts anatomical features from a 3-dimensional B-mode ultrasound liver image for image registration. An image forming unit forms a 3-dimensional ultrasound liver image based on ultrasound signals reflected from the liver. A diaphragm extracting unit extracts a diaphragm region from the 3-dimensional B-mode ultrasound liver image. A vessel extracting unit extracts vessel regions from the 3-dimensional ultrasound liver image. A diaphragm refining unit refines the extracted diaphragm region with the extracted vessel regions to remove clutters from the diaphragm region. A registration unit extracts sample points from the diaphragm region with the clutters removed and the vessel regions for image registration.

    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.
