CAPSULE FOR MEASURING FLOW INFORMATION USING X-RAY AND MEASURING METHOD USING THE SAME

摘要

PURPOSE: A capsule for measuring flow information using X-ray and a measuring method are provided to measure flow in a human body in a micrometer accuracy. CONSTITUTION: A capsule(1) for measuring flow information using X-ray comprises inner wall material(12) and outer wall material(11). The capsule contains biocompatible polymer, organic contrast agent, and cross linking agent. The organic contrast agent is iodine-based contrast agent, barium-based organic contrast agent, or mixture thereof. The cross linking agent is glutaaldehyde. A method for measuring flow information using X-ray is flow visualization or X-ray particle image velocimetry(PIV).
