自1895年德国物理学家伦琴发现X线并拍下第一张手的X线片开始,之后的一百多年里,医学影像技术取得了飞速发展。1971年亨氏菲尔德发明了CT,将传统X线成像变成断层及数字影像,奠定了现代医学影像学的基础。随后MRI、PET、DSA、SPECT及分子成像和光成像的出现,使医学影像在显示形态学状态之外,还能反映组织和器官功能,并在分子和细胞水平显示组织、器官的化学成分和代谢变化。此外,RIS、HIS
Since the 1895 German physicist Roentgen discovered X-ray and took the first hand X-ray film began, after more than 100 years, medical imaging technology has made rapid development. In 1971, Heinzfeld invented the CT, the traditional X-ray imaging into a fault and digital images, laid the foundation for modern medical imaging. The subsequent appearance of MRI, PET, DSA, SPECT and molecular imaging and light imaging has enabled the medical imaging to reflect the function of tissues and organs in addition to displaying the morphological state and show the chemical composition and metabolism of tissues and organs at the molecular and cellular levels Variety. In addition, RIS, HIS
