摘要： An ultrasound imaging system is provided which produces gray scale images of the anatomy simultaneous with Doppler signal processing so as to provide a single real-time image that shows not only the vascular anatomy and surrounding tissue but also flow events in the vascular compartment. A phased linear array having near-continuous focus over the scanning field provides high resolution and very small Doppler sample volumes. The system tests incoming signals from throughout the scanning field for amplitude, phase and frequency so as to determine B-mode data, motion presence and direction, and echo source velocity.

摘要： The present invention relates to an ultrasound system. A control generates a first control signal for a B-mode scan and a second control signal for a C-mode scan A transmit/receive unit transmits ultrasound signals along a plurality of scan lines set in a target object and form receive signals based on the ultrasound echo signals reflected from the target object. The receive signals include first receive signals corresponding to the scan lines and second receive signals corresponding to a portion of scan lines within the color box. The image processing unit forms a B-mode image and a C-mode image based on the first and second receive signals, and combine the B-mode image with the C-mode image to form a BC-mode image. The control unit computes a time ratio of a first time required to form the B-mode image to a second time required to form the C-mode image, and generates a third control signal for a B-mode scan along scan lines, which are not within the color box, based on the time ratio to form third receive signals. The image processing unit forms a B-mode image based on the third receive signals and the second signals.
