Abstract:
1. An ultrasound diagnostic apparatus, comprising: a storage implemented in the ultrasound diagnostic apparatus, the storage configured to store cine data constructed with a plurality of consecutive image frames based on signal processing upon ultrasound echoes from a target object if a real-time display mode is set; an image processor implemented in the ultrasound diagnostic apparatus and coupled to the storage, the image processor configured to set a plurality of marks to a plurality of image frames among the consecutive image frames, and read the storage to form preview images of the image frames with the marks set, wherein the preview images are formed in smaller sizes than the image frames, and the preview images are linked to the corresponding image frames and stored in the storage in association with the corresponding image frames; a display implemented in the ultrasound diagnostic apparatus and coupled to the image processor, the display configured to display at least one preview image among the preview images at a predetermined position on a screen of the display; and a user input device implemented in the ultrasound diagnostic apparatus, the user input device coupled to the image processor and configured to receive a bookmark setting instruction from a user, wherein the image processor is further configured to set bookmarks to a first frame and a last frame of a cine image to be replayed among the consecutive image frames in response to the bookmark setting instruction, and if a freeze mode is set from the real-time display mode in response to an instruction inputted from the user input device, the image processor may read out the preview images on which the marks are set and display the read-out preview images, and when the user input device receives a user input for selecting one of the read-out preview images, on which the marks are set, displayed on the display, the image processor reads out frame data corresponding to the selected preview image and performs image processing upon the read-out frame data to thereby form a frame image signal, and the display further displays a frame image based on the frame image signal, if a cine replay mode is set from the real-time display mode in response to an instruction inputted from the user input device, the image processor may read out preview images on which the bookmarks are set among the preview images on which the marks are set and display the read-out preview images, bookmark information including information of the first frame and the last frame of the cine image is indicated at the read-out preview images displayed on the display, when the user input device receives a user input for selecting one of the read-out preview images, on which the bookmarks are set, displayed on the display, the image processor reads out the frames of the cine image based on the bookmark information and performs image processing upon the frames of the cine image to thereby form the cine image, and the display further replays the cine image.
