Abstract: The invention proposes a method for generating ultrasonic panoramic image and an ultrasonic device. The invention first analyzes the degree of overlap area between two black-and-white images and determines the Doppler signal error of two corresponding color images once the overlap area is large enough. A plurality of black-and-white characteristic images and color characteristic images are then determined from the captured black-and-white images and color images and used for generating a black-and-white panoramic image and a color panoramic image respectively using an image stitching algorithm. The color panoramic image is then overlaid with the black-and-white panoramic image to form an output panoramic image.

Abstract: An ultrasound needle positioning system includes an ultrasound probe and a processor. The ultrasound probe is used to capture a plurality of sets of needle insertion images. Each set of needle insertion images includes a plurality of needle insertion images corresponding to a needle body at a predetermined insertion angle. The processor is coupled to the ultrasound probe, and is used to train a first convolutional neural network according to at least one set of needle insertion images in the plurality of sets of needle insertion images to generate needle body positioning information after the needle body is inserted. The needle body positioning information includes a reference position, a length, and/or a width corresponding to the needle body at at least one predetermined insertion angle.
