Transformation of a Three-Dimensional Flow Image

摘要

A method of transforming a three-dimensional ultrasound Doppler image that represents flow within a subject uses a three-dimensional ultrasound intensity image that has a common field of view and represents structure within the subject. Within the three-dimensional structural image, there is identified a three-dimensional reference surface that represents the location of a surface of the structure represented by the three-dimensional structural image. A mapping is derived that maps the three-dimensional surface into a two-dimensional plane. The mapping is applied to map the three-dimensional surface of the flow image at the location represented by the three dimensional reference surface into a two-dimensional flow image.

1. A method of transforming a three-dimensional flow image that represents flow within a subject, wherein the method additionally uses a three-dimensional structural image that has a common field of view with the three-dimensional flow image and that represents structure within the subject, and the method comprises:
identifying from the three-dimensional structural image a three-dimensional reference surface that represents the location of a surface of the structure represented by the three-dimensional structural image; deriving a mapping that maps the three-dimensional reference surface into a two-dimensional plane; and generating a two-dimensional flow image by applying the mapping to map a surface of the three-dimensional flow image at the location represented by the three-dimensional reference surface into the two-dimensional flow image.
