PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment capable of accurately adjusting the focus of a luminance image by calculating an accurate environmental sonic velocity, without reference to the state of a diagnostic region of a subject.SOLUTION: Ultrasonic diagnostic equipment includes: an ultrasonic transmission/reception unit which transmits an ultrasonic beam to a subject and which outputs reception data by receiving an ultrasonic echo produced by having the ultrasonic beam reflected from the subject; and an environmental sonic velocity calculation unit which acquires first reception data having a frequency lower than second reception data for generating a luminance image of the subject and used to calculate an environmental sonic velocity being a sonic velocity in the subject, and which calculates the environmental sonic velocity by analyzing the acquired first reception data. |
