Abstract (en)
[origin: WO2019055016A1] Techniques for intravascular ultrasound image processing of blood-filled or blood-displaced lumens are disclosed. A catheter assembly may include an intravascular imaging device with an imaging element to image a vasculature and generate imaging data. An imaging engine, including a programmable processor, may communicate with the intravascular imaging device. The imaging engine may determine a lumen state of the vasculature, the determined lumen state indicative of whether the vasculature is blood-filled or blood-cleared. The imaging engine may perform signal processing to enhance the generated image data. Finally, the imaging engine may generate an image based on the enhanced imaging data and the determined lumen state.
