Vessel wall detection and blood noise reduction in intravascular ultrasound imaging

摘要

Scattering from blood (blood noise) limits the contrast between the vessel wall and the lumen in intravascular ultrasound imaging. This makes it difficult to localize the vessel wall, especially in still images. This paper presents a method for automatic detection of vessel walls and reduction of blood noise based on correlation of the RF-signal between adjacent frames. Regions detected as vessel wall are displayed with no modifications, while regions detected as blood noise undergo a hard rejection.
