The invention discloses a method and device for magnifying an ultrasonic image. The method comprises the steps that abandoned points in initial black-and-white image data and abandoned points in initial color image data are respectively removed according to image magnifying parameters to obtain first black-and-white image data and first color image data, the downsampling operation is carried out on the first black-and-white image data and the first color image data respectively according to the downsampling rate of the first black-and-white image data and the downsampling rate of the first color image data to obtain second black-and-white image data and second color image data, data scanning coordinate transformation is carried out on the second black-and-white image data and the second color image data respectively to obtain target black-and-white image data and target color image data, and the target black-and-white image data and the target color image data are converted into a target black-and-white image and a target color image respectively through a MAP table. By means of the method and device, the problems that an image in the prior art is poor in effect and low in resolution are solved, and the effect that the black-and-white image and the color image are consistent in method magnification and magnifying effect is achieved.
Description
technical field [0001] The present invention relates to the field of image processing, and in particular, to a method and device for enlarging an ultrasonic image. Background technique [0002] The ultrasound imaging process is a real-time process, and the data is generated frame by frame in real time. For real-time imaging images, we can do local real-time magnification, so that the doctor can better see the imaging details and facilitate the doctor's diagnosis; the traditional meaning The magnification is to determine the effective range according to the magnification, and then adjust the point spacing and line spacing of a frame of image to achieve the magnification effect. In this traditional magnification method, the effective information in a small area does not change. Therefore, when the magnification is larger, the point spacing and line spacing are larger, the image information is relatively less abundant, and the distortion after interpolation is larger.
