1. An ultrasonic diagnostic apparatus comprising:
- an image acquisition unit which acquires a plurality of ultrasonic images by a first imaging mode which executes a first ultrasonic transmission that destroys a contrast agent and a second imaging mode which executes the second ultrasonic transmission that visualizes a process of flowing in of contrast agent without practically destroying the contrast agent in examination before stress and examination under stress of a subject implemented in time series;
a storage unit which stores a plurality of ultrasonic images in each examination and in each imaging mode;
an image generator unit which generates images acquired in the same imaging mode in the examination before stress as reference images in accordance with the stored ultrasonic images, when current images are acquired in the predetermined imaging mode in the examinations under stress; and
a display unit which simultaneously displays the reference image and the current images.

Abstract
In the event that images are acquired for multiple cross-sections (multiple phases) by a predetermined imaging mode in an examination under stress to a subject, images of the same phase acquired by the same imaging mode in an examination before stress to the subject is read and simultaneously displayed as reference images together with current images. The operator can bring the cross-sectional position in the examination under stress in correspondence to the position of the examination before stress by comparing the displayed reference images with the current image.
