量子成像及其生物医学应用进展

量子成像是是利用辐射场的量子涨落来获取物体信息的一种非局域成像方法。本文介绍了量子成像的一般概念，包括其理论基础、实验装置和发展历史。基于它在空间分辨率、抗干扰能力和图像采集时间等方面的独特优势，本文介绍了其在生物医学领域的潜在应用前景，主要应用有:鬼磁共振血管造影技术，量子成像可以在更大的并行加速因子条件下，近乎完美地对背景噪声进行抑制；量子光学相干断层扫描技术，量子成像在处理群速度色散和图像分辨率方面有着绝对优势；X射线量子成像，可以在保持图像质量的前提下降低辐射剂量。此外，若在单像素成像实验中考虑介质的多重散射，量子成像则可以实现对生物组织的单像素透射成像。

Quantum imaging and its application prospects in biomedicine

Abstract: Quantum imaging is a non-local imaging method based on quantum fluctuation in radiation field. Herein some general concepts of quantum imaging, including theoretical fundament, experimental apparatus and its development of history, are reviewed. With the unique advantages in spatial resolution, anti-interference and image acquisition, quantum ghost imaging has potential applications in several biomedical fields, mainly as follows: (1) ghost magnetic resonance angiography which can achieve near perfect background suppression with much greater parallel acceleration factors; (2) quantum optical coherence tomography which has absolute advantages in dealing with the group-velocity dispersion and improving image resolution; (3) X-ray ghost tomography which can greatly reduce radiation damage while remaining the quality of image. Moreover, if considering the objects embedded in multiple scattering media, transillumination imaging through biological tissue by single-pixel detection can be realized by quantum imaging.
