Ultrasound image processing apparatus
First Claim
1. An ultrasound image processing apparatus comprising:
- an image storage unit which stores ultrasound image data of a plurality of time phases;
an image processor which searches image data of a search time phase for a movement point corresponding to a set point which is set in image data of a reference time phase, based on a correlation calculation between image data; and
a diagnostic information generator which determines a primary direction of movement of the set point over a plurality of time phases based on the movement points searched over a plurality of time phases and obtains diagnostic information by evaluating the movement of the set point with the primary direction as a reference.

Abstract
Ultrasonic image data from a plurality of time phases are stored in an image storage unit (22). A pattern matching unit (30) searches the image data in a search time phase for moving points corresponding to set points in the image data in a reference time phase, on the basis of a correlation operation performed on the image data. In this way, moving points for set points are searched across a plurality of time phases. A diagnostic information generating unit (40) then determines the main direction of movement of the set points across the plurality of time phases based on the moving points searched across the plurality of time phases, and diagnostic information is obtained by evaluating the movement of the set points with reference to the main direction.

13. A non-transitory computer-readable recording medium recording a program which, when executed, causes a computer which processes ultrasound image data of a plurality of time phases, to realize:
-
an image processing function to search image data of a search time phase for a movement point corresponding to a set point which is set in image data of a reference time phase, based on a correlation calculation between image data; and a diagnostic information generation function to determine a primary direction of movement of the set point over a plurality of time phases based on the movement points searched over a plurality of time phases and to obtain diagnostic information by evaluating the movement of the set point with the primary direction as a reference.
