摘要
The present invention is methods, and apparatus for blood speckle detection for enhanced intravascular ultrasound imaging. The invention utilizes the fact that the energy scattering strength from blood exhibits a high frequency dependency (67, 69), while the scattering strength from tissue lacks a strong frequency dependency (63, 65). In specific embodiments, the present invention may provide a particularly simple and useful solution for addressing the problem of blood speckle in intravascular ultrasound imaging, especially in situations where the blood may have a scattering strength similar to that of tissue and/or where the blood is moving slowly or not at all.
