摘　　要：GE公司新一代多功能ECT,可安装CT(Hawkeye)选件。该CT能完成对SPECT图像或符合线路PET图像的衰减校正,使核医学图像能更接近的反映核素在人体内的真实分布情况。另外,同机SPECT和CT或符合线路PET和CT的图像融合,为核医学的功能图像提供了解剖学定位。GE company produced a multifunctional ECT of new generation, which can be equipped with CT option called Hawkeye. The CT option can make attenuation correction to SPECT image or coincidence PET image, which makes the image of nuclear medicine closer to the real situation of distribution of radioactive nuclide in patients. In addition, the image fusion of SPECT and CT or coincidence PET and CT in one modality provides anatomic localization for the functional image of nuclear medicine.
