Multiple sample volume spectral Doppler |
摘要 |
An ultrasonic diagnostic system simultaneously monitors the Doppler signal of a plurality of sample volumes within the body of a patient which are aligned around a point of diagnostic interest within the body. The Doppler signal of the sample volume which best satisfies a predetermined criterion, such as that exhibiting the greatest Doppler signal power, is displayed to the user. When a different sample volume meets the criterion the Doppler signal display changes to display the Doppler signal of the newly identified sample volume. In one embodiment the spectral Doppler displays of a number of sample volumes are displayed concurrently and that which best satisfies the chosen criterion is identified to the user. In another embodiment the identified sample volume is identified in a B mode display of the sample volume area while the spectral Doppler display from the identified sample volume is displayed. The two dimensional B mode display can also be extended to a three dimensional display of a volume of individual sample volumes.
