Improvement of ultrasound speckle image velocimetry using image enhancement techniques |
| abstract |
• SIV applies a cross-correlation algorithm to consecutive B-mode speckle images of blood cells. • The intensity and size of speckles are heterogeneous according to hemodynamics. • The inhomogeneous distribution of speckles decreases the measurement accuracy. • Image-enhancement techniques were applied to images to improve the measurement accuracy. • The CLAHE method shows the best improvement in the blood flow measurement. |
