| 摘要 |
An ultrasonic diagnostic apparatus wherein a three dimensional space is scanned by ultrasonic beams and echo signals are received simultaneously in parallel to produce ultrasonic information. During operation, transmitting/receiving conditions are selected from a plurality of transmitting/receiving conditions. Operation is then switched at a predetermined period between the selected transmitting/receiving conditions so that the three dimensional space is scanned by ultrasonic beams and echo signals are alternately received, at the predetermined period, under the selected transmitting/receiving conditions. Image information for each selected transmitting/receiving condition is obtained and respective ultrasonic images corresponding to each transmitting/receiving condition are simultaneously displayed.
