成像深度对光声层析成像的影响
Influence of imaging depth on photoacoustic tomography
摘要
Abstract
In order to research on the influence of imaging depth on photoacoustic tomography,the multiple linear array detectors is used for detection imaging at limited-view.Both simulation and experimental results show that the reconstructed image qualities are better as the absorber is closer to the detectors.Image distortion becomes obvious when the ratio of detectors size to the imaging depth is less than 1 .We also demonstrated that the image distortion can be significantly reduced by rotating the multiple linear array detectors.This study helps the design of scanning strategy and the evaluation of reconstructed images.关键词
