3D ultrasonic diagnostic apparatus |
摘要 |
A three-dimensional ultrasonic diagnostic apparatus includes a two-dimensional array type of ultrasonic probe. A three-dimensional scan operation of scanning a three-dimensional region within a human body under examination with ultrasound and a two-dimensional scan operation of scanning a two-dimensional plane within the three-dimensional region with ultrasound are selectively performed by a beam former unit. Under the control of a controller, the three-dimensional scan operation is repeated intermittently and the two-dimensional scan operation is repeated during the interval between each three-dimensional scan. Three-dimensional ultrasonic image data concerning the three-dimensional region is produced on the basis of received echo signals obtained by the three-dimensional scan operation. Two-dimensional ultrasonic image data concerning the two-dimensional plane section is produced on the basis of received echo signals obtained by the two-dimensional scan operation.
