  • Patent number: 6335979
    Abstract: A list of a plurality of reference images is displayed. Parameters pertaining to signal acquisition, image generation, and image display are related to each of these reference images. When the operator selects one desired reference image from the list, a signal is acquired and an image is generated and displayed in accordance with the parameters related to the selected reference image. The only operation which the operator must perform is to select a reference image visually close to a desired medical image. The apparatus automatically sets detailed signal acquisition parameters, image generation parameters, and image display parameters which the operator need not know.
