Ultrasonic Image Processing Apparatus and Program
A guidance image generation unit generates a guidance image in which setting position information and setting order information of each manually set representative point are marked on a schematic diagram schematically representing an organ image included in an ultrasonic image. A schema diagram schematically shows a tomographic image of the heart. A position marker is a specific example of the setting position information and a number label is a specific example of the setting order information. A plurality of position markers indicate positions corresponding to a plurality of feature points in the schema diagram schematically showing an apical three-chamber (A3C) view. A plurality of number labels indicate setting orders of the plurality of feature points.
1 . An ultrasonic image processing apparatus comprising:
a representative point setting unit which manually sets at least one of a plurality of representative points in an ultrasonic image based on data obtained by transmitting and receiving ultrasonic waves according to an operation by a user; and
an image generation unit which generates a guidance image in which setting position information and setting order information of each manually set representative point are marked on a schematic diagram schematically representing an organ image included in the ultrasonic image.
