| 摘要 |
An ultrasonic diagnostic apparatus according to the present invention including a storage unit that stores reference three-dimensional volume data of an examinee obtained by an image pickup device, an ultrasonic probe that is inserted in a body cavity of the examinee and can perform ultrasonic scanning in a radial direction, an ultrasonic image generating unit that generates an ultrasonic tomographic image on the basis of a reflection echo signal from the ultrasonic probe, a position detector that detects a position and a posture of the ultrasonic probe on the basis of a sensor attached to the ultrasonic probe, an image generating unit that generates a scanning position mark representing an ultrasonic scanning position on a tomographic plane parallel to a travel direction of the ultrasonic probe from the reference three-dimensional volume data of the storage unit on the basis of an output of the position detector, and a display unit that displays the ultrasonic tomographic image and the scanning position mark.
