A nonuniform sampled coherent pulsed Doppler ultrasonic velocimeter with increased velocity range
Coherent pulsed Doppler ultrasonic velocimeters cannot measure large blood velocities in deep vessels. To overcome this limitation, a nonuniform sampling method is proposed. The method is based on adding a delayed sampling sequence interlaced to the conventional one. The time interval between two co...

| Zusammenfassung: | Coherent pulsed Doppler ultrasonic velocimeters cannot measure large blood velocities in deep vessels. To overcome this limitation, a nonuniform sampling method is proposed. The method is based on adding a delayed sampling sequence interlaced to the conventional one. The time interval between two consecutive samples can be continuously adjusted to avoid undesirable sample volumes. Experimental results are shown, confirming theoretical expectations that the maximum measurable velocity and the maximum measurable velocity width are doubled |
