ULTRASOUND DIAGNOSIS APPARATUS
First Claim
1. An ultrasound diagnosis apparatus generating an ultrasound image of inside of a test object based on ultrasound signals reflected and received from the inside of the test object, the ultrasound diagnosis apparatus comprising:
- a candidate region extracting unit configured to extract a plurality of candidate detection regions in a needle position range corresponding to a position of a puncture needle inserted into the test object;
a needle identification range setting unit configured to determine a needle identification range including the needle position range from the ultrasound image based on the extracted candidate detection regions;
a needle position range estimating unit configured, to determine an estimated range of the needle position range in the needle identification range based on a value indicating an aggregation state related to a distribution of the candidate detection regions in the needle identification range; and
a needle emphasizing unit configured to perform a process for emphasizing the estimated range in the ultrasound image.
