Ultrasound blood flow/tissue imaging system

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 li...

Beschreibung
Zusammenfassung:	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.
