ULTRASONIC DIAGNOSTIC APPARATUS AND SOUND OUTPUT METHOD FOR ULTRASONIC DIAGNOSTIC APPARATUS
First Claim
1. An ultrasonic diagnostic apparatus comprising:
- a three-dimensional information acquisition section which acquires three-dimensional fluid information including at least a three-dimensional flow direction of a specimen on the basis of a Doppler signal output from an ultrasonic probe, the specimen being at least a fluid in a particular part; and
a three-dimensional sound output section which outputs the three-dimensional fluid information as a sound in a three-dimensional space.

Abstract
A vector norm N, an azimuthal angle θ and an angle of elevation φ which represent the velocity (blood flow velocity) of a specimen such as blood flow are acquired by a three-dimensional angle correction velocity vectorization section as three-dimensional fluid vector data indicating the three-dimensional flow direction and flow volume of the specimen such as the blood flow on the basis of Doppler signals corresponding to reception beams F1 to F4 received from a range gate RG by a two-dimensional ultrasonic probe. An audio output [y] for a three-dimensional sound system is generated by a velocity vector conversion processing section on the basis of the three-dimensional fluid vector data [N, θ, 100 ], and a three-dimensional sound system is driven.
