超音波診断装置
Document Type and Number:
Japanese Patent JP4500336
Kind Code:
B2
Abstract:
A transmission and reception unit (14) controls probes (11, 12) to form an ultrasound beam (40) which intersects a bone (52) and obtains a reception signal. A beam evaluating unit (24) evaluates an intersection state of the ultrasound beam (40) with respect to the bone (52) based on a shape of an envelope of the reception signal. More specifically, the beam evaluating unit (24) determines a quality of the reception signal based on a height and a slope of a hill-like portion, included in the envelope, corresponding to the bone (52) and evaluates the intersection state of the ultrasound beam (40).
