Ultrasound diagnosis apparatus

An ultrasound apparatus comprising:

• an image generator which generates an ultrasound image of an inside of a subject based on ultrasound signals which are reflected off at the inside of the subject and received;
• a needle position specifier which, with respect to each region in the ultrasound image, obtains a deep region feature value relating to signal intensity in a region deeper than a region subject to judgment in relation to an ultrasound signal distribution along an emission direction of the ultrasound signals emitted in the subject, and which specifies a position of a puncture-needle which is inserted in the subject based on a shadow region produced by the puncture-needle when the ultrasound signals enter the subject;
• a needle emphasis processor which carries out a process for emphasizing the position of the puncture-needle which is specified in the ultrasound image by processing the ultrasound image to clarify an appearance of the puncture-needle in the ultrasound image;
• and
• a display which displays the ultrasound image in which the appearance of the puncture-needle has been clarified by the processing carried out by the needle emphasis processor.
