Xcounter's Actaeon detector is capable of x-ray imaging at 1000 fps, providing enough time and spatial resolution to quantify details. A new method to obtain the blood flow details of patients' specific geometry through experiments shows a combination of cross-correlation and optical flow methods to find the velocity of the microsphere contrast particles at 1000 fps. Microspheres were prepared by immersing them in iodine contrast media to provide radiopaque opacity and injected during x-ray irradiation into a 3D printed patient specific vascular model. Actaeon's high sensitivity mode captures images at 1000 frames per second for 2.4 seconds and thus provides quantitative data about the flow details in a vascular model and qualitative information about the flow at different time points during the collection period. This method can realize the new measurement of blood flow characteristics in specific vascular systems of patients. Validating the accuracy of this method was conducted by generating an image sequence with a microsphere with known displacement and velocity.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
