摘　　要：医学影像物理和技术是医学物理学的重要分支 ,重点解决成像、图像处理与分析以及医学图像在临床应用中的物理问题、算法和软硬件设计。治疗中的医学影像可以用于制定治疗计划、在治疗过程实施影像监督 ,以及通过对治疗监督时采集的数据的图像重建实现对治疗计划的验证。广泛用于疾病诊断、治疗、教学和科研的医学影像是人体信息的载体。当前医学影像的世界前沿是功能成像 ,主要内容是对人的生理和心理功能的成像。无论生理还是心理成像 ,都和人体内的生物大分子合成及其行为特征以及基因的表达有关 ,所以 ,对人体内生物大分子和基因反义核酸水平上的动态成像是整个成像领域研究的前沿。这些成像方法和技术的发展以及在医疗机构中的广泛使用 ,将引起医学领域新的革命并促进医疗机构的重大改革。The physics and technologies (P&T) of medical imaging is one of the main branches of medical physics, which deal with the problems on physics, algorisms, as well as the designs of imaging facilities both for hardware and software in medicine. The information on medical imaging could be used to make the therapeutical plan, monitoring the treatment processing, and verification of the plan via reconstruction of the data during therapy. Therefore, medical imaging is not only used for diagnosis, but also for therapy, as well as for basic research and education. The frontal of medical imaging is functional imaging, which is used for physiological and psychological imaging for human subject. But all physiological and psychological information of human subjects is related with biological molecules and genetic expression in vivo, which is the frontal of medical imaging physics. That means molecular and anti-nucleic acid imaging will be the most important direction of medical imaging. Use of modern technology has speeded up the change of medical organization reformation process.
