ULTRASONOGRAPH AND CONTROL PROGRAM OF ULTRASONOGRAPH

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonograph and a control program of the ultrasonograph capable of reducing various effects caused by discrepancy of isotropy evaluated based on a scanning line density in an electronic scanning direction and the scanning line density of a swinging direction from an intended value in a mechanical scan using a mechanical 4-dimensional probe. SOLUTION: This ultrasonograph 1 having an ultrasonic probe 2 mechanically swung in the direction different from the electronic scanning direction is provided with a scanning method calculation part 15 setting a scanning condition so that the isotropy indicating an equality level between the scanning line density in the swinging direction of the ultrasonic probe and the scanning line density in the electronic scanning direction becomes the intended isotropy by the mechanical scanning using the ultrasonic probe 2, and a hardware control method calculation part 15 generating a control signal of the ultrasonic probe 2 from the scanning condition set by the scanning method calculation part 15.
