An Endoscopic Optical Coherence Tomography System with Improved Precision of Probe Positioning
An improved optical coherence tomography system equipped with an endoscopic probe is presented. A key feature of the described device is the possibility of high-precision positioning of the endoscopic probe. This effect is achieved by the use of microelectromechanical systems for assessing the angular velocity and acceleration. The scanning process is optically synchronized with the process of calculation of the spatial coordinates of the endoscopic probe. The expediency of using the developed system for real-time evaluation of the biomechanical properties of blood vessel walls or their phantoms is discussed.
