V Flow changes the way

Based on the innovative ZST+ platform, plane wave technology and multi-directional transmissions and receptions with interleaved focused waves, resulting in a high frame rate novel ultrasound-based technology called V Flow released on Resona Series breaks the angle-dependent limitation on traditional color Doppler. Rather than a series of static images, the fluidity will be displayed with dynamic arrows indicating the flow process. Both the magnitude and direction of the flow velocity can be measured at any locations in the vessel within ROI.

Clinical Case

Case 1

The first case is the diastolic hemodynamic characteristics of the common carotid bifurcation, external carotid artery, internal carotid artery and internal jugular vein. The first is a color flow image, and the second is a V Flow image. Compared with color flow imaging, V Flow has a high frame rate of up to 1000 frames/sec. It has no angle dependence and can accurately display the blood flow velocity and the hemodynamics of the diastolic blood flow of external carotid artery, internal carotid artery and internal jugular vein.

Case 2

The second case is a plaque near the internal carotid artery at the bifurcation of the carotid artery. Blood flow speeds up in the stenosis area after the systolic phase passes through the plaque stenosis area, and swirls form after the stenosis. This truly demonstrates the hemodynamic characteristics of blood flow passing through the plaque.

Internal Carotid Artery Plaque

Case 3

The third case is the systolic hemodynamic characteristics and precise quantitative analysis of the internal and external carotid arteries at the bifurcation of the common carotid artery.

Clinical Values

- Millisecond level temporal resolution which can detect the tiny hemodynamic changes and provide more valuable information than conventional color Doppler

- Grayscale display intuitively shows the spatial distribution of blood flow, which shows better flow sensitivity than conventional power Doppler

- Arrow color/ length, and direction indicate blood flow velocity and direction respectively which helps doctors easily capture abnormal hemodynamics change

- Complex flow imaging illustrating laminar, vortex, secondary, and retrograde flows allows better understanding hemodynamics in different conditions
