摘要
急性心脑血管疾病是人类健康的头号杀手, 将光声成像与医学内窥技术相结合的血管内光声(IVPA)成像技术有望为心脑血管内易损斑块的检测以及指导介入治疗提供更可靠的参考指标。目前对IVPA 成像的研究尚处于起步阶段, 对其图像重建的研究也主要是借鉴其它比较成熟的成像技术的重建理论。本文在介绍IVPA 成像原理的基础上, 指出在重建IVPA 图像中亟待解决的两个问题, 并对目前可以应用到IVPA 图像重建中的主流算法进行介绍和分析。
Abstract
Acute cardiovascular disease is the leading killer of human health. Intravascular Photoacoustic (IVPA) imaging modality, which combines photoacoustic imaging and medical endoscopic technique, is expected to provide more reliable information about the vessel and plaques for the detection of vulnerable plaques and the interventional treatment of cardiac diseases. Till now, the study of the IVPA imaging has been still in its beginning stages. The study of the IVPA image reconstruction also mainly learns from the reconstruction algorithms of other mature imaging techniques. Based on the introduction of the IVPA imaging principle, two problems to be solved in IVPA image reconstruction are pointed out and some main reconstruction algorithms that can be applied to the IVPA image reconstruction are introduced and analyzed.
