Method and apparatus for ultrasonic blood flow display

摘要

In a power Doppler ultrasonic blood flow display apparatus, according to a moving signal Z representing moving of a blood flow display region, display changing means comprising changers (77, 78) and a change controller (79) displays a B-mode image also to a blood flow display region (84) while the blood flow display region (84) is moved, and displays a blood flow image when the moving of the blood flow display region (84) is stopped. Consequently the B-mode image of the target can be easily caught even while the blood flow display region is moved.
