光学相干层析成像旋转失真评价研究
Study on the Evaluation of Rotational Distortion in Optical Coherence Tomography
摘要
Abstract
Optical coherence tomography (OCT) is an emerging branch of medical endoscopy, which can rapidly acquire high-resolution 3D images. The advancement of OCT catheter design enables OCT for the diagnostics of various diseases near tissue surface. The clinical translation of OCT is accelerating in many ifelds such as cardiovascular diseases, gastrointestinal diseases, pulmonary diseases and urinary diseases. Rotation distortion (RD) is a common problem with OCT endoscopy, which reveals the mechanical properties of the catheter and may severely deteriorate the integrity of images. Currently, no standard provides deifnition or testing method for RD. In this paper, the characteristic of RD was discussed and a quantitative method to evaluate RD was proposed. The results provided useful reference for the quality control of OCT endoscopy.关键词
