生物医学影像新进展

The New Development of Biologic Medical Image

生物医学影像是21世纪发展起来的新技术,是影像学从大体形态学向微观形态学、生物代谢、基因成像发展的必然趋势。生物医学成像研究主要集中在分子成像、功能成像、细胞成像和基因成像等方面。分子成像基础研究的工具有基因重组技术、X线晶格成像、快速物质波谱分析、计算机和机器人技术。发展和测试体内特异性分子成像、光学成像与显微CT/MRI/PET/光学成像以及PET,SPECT等,适用于分子、基因的显像和定位。结合微创性操作的影像指导技术,可用于指导病变的治疗和监测。有利于疾病的早期诊断,即在疾病的功能性障碍发展早期识别病变,使疾病的诊断和治疗愈来愈多地使用创伤性更小、精确度更高的成像技术以及影像指导下的手术操作,是研究生命科学的新技术。

Biologic medical image is a new technique developing in the 21 century. It's a natural tendency of the image that develops from macro morphology towords the direction of micro morphology, biologic metabolism, gene image - forming. The mainly study concentrate on the aspect of moleclar image - forming, functional image -forming, cellular image -forming and gene image -forming. There are tolls of basic study of molecular image -forming such as gene recombinant technique. X - ray crystal image - forming, fast speed substance spectrum analysis, computerzed and man - machine technique, developing and testing the specific molecular image -forming within the body. PET. SPECT. optical image - forming, and micro CT/MRI/PET/ optical image -forming, they are suitable for molecular and gene's developing and orientation. To direct therapy and monitor of the lesions using the image direct technique of the minimal invasive operation. It can help the early diagnosis of the diseases. That means we can identify the lesions when the functional disturbance occur in its early stage. We can diagnose and treat the disease using more and more image - forming technique of less traumatic, more accurate to do the operation.
