Adaptive noise reduction in ultrasound imaging

The solution in assisting practitioners in venipuncture is to design a full autonomous venous access device, which integrating multiple methods of venous detection in performing precision cannula placement [1]. Particularly, B-mode ultrasound and near-infrared imaging techniques are studied to conduct vessel reconstruction. However, low light level intensity and inherent speckle noise are problematic for accurate vessel detection. Thus, an adaptive filtering method is necessary in vessel reconstruction.
