IMAGING CATHETER USING LASER PROFILE FOR PLAQUE DEPTH MEASUREMENT |
摘要 |
A device, system, and method for measuring the depth of a material layer such as a blood vessel plaque layer is disclosed. A fiber optic bundle housed in a balloon catheter projects a laser dot toward a conical mirror, which reflects the dot perpendicularly onto the surface of the plaque. The laser dot is reflected back from the plaque layer with a substantially Gaussian intensity profile. The conical mirror directs the reflected image back to the fiber optic bundle, which delivers the image to a sensor. The depth of the plaque layer can be determined by comparing the diameter of the image intensity profile to a pre-obtained normalized data set. |
