随着激光技术、计算机技术与图像处理分析技术的飞速发展, 单一模态的医学影像技术正向一体化、多模态及跨尺度影像技术进行革命性转变。多模态影像技术不仅可以实现对同一生物体进行多角度、多参数及分子层面的结构与功能综合特征信息的提取, 而且可以弥补单一模式存在的局限性与不足, 从而提高疾病早期检测的准确性, 为患者提供更加经济合理、精准有效的诊疗方案, 对提高人们的生活质量具有非常重要的临床意义。本文重点阐述目前光声/超声双模态成像技术在生物医学以及脑相关疾病中的应用及新进展, 系统讨论了该双模态融合技术在未来生物医学领域中的发展前景。

With the rapid development of laser technology, computer technology and the improvement of image processing and analysis technology, the biomedical image with a single mode is heading toward multimode, and its scale is undergoing a revolutionary transformation.Multi-modality imaging technology can not only realize the multi-angle, multi-parameter structure and function of the same organism and the extraction of comprehensive feature information at the molecular level, but also make up for the deficiency of single mode.In this way, it can improve the accuracy of early detection of diseases and provide patients with more economical, reasonable, accurate and effective treatment plans, which is of great clinical significance for improving people’s quality of life.This paper focuses on the application and new progress of photoacoustic/ultrasound dual-mode imaging technology in biomedical field and brain-related diseases.Systematically discusses the prospect of this fusion technology in the future biomedical field.
