Abstract:
A method of synthesizing a panorama image from ultrasonic images, comprising:a step of obtaining data of a plurality of consecutive ultrasound frame images constructing an ultrasound motion image;a step of obtaining a shift amount of a specific area of the plurality of consecutive ultrasound frame images by use of correlation of a characteristic amount derived from said specific area of the plurality of consecutive ultrasound frame images;a step of obtaining a rotation amount of the specific area of the consecutive ultrasound frame images by use of distributions of shift amounts, each of which is derived from a difference between the characteristic amount of corresponding partial areas obtained by dividing each of the consecutive ultrasound frame images in one axis direction;a step of detecting positional relation data between the plurality of consecutive ultrasound frame images by use of the shift amount and rotation amount; anda step of connecting the plurality of ultrasound frame images by using the positional relation data to synthesize panorama image data.
