The application of terahertz imaging in tumor diagnosis / 肿瘤

ABSTRACT

Terahertz wave is a new coherent far infrared source that spans the gap between microwave and infrared radiation. Compared with microwave, X-ray and NMR (nuclear magnetic resonance) imaging, terahertz imaging has the advantages of high resolution and no harm to biological samples, which has been comprehensively applied in biomedical fields in recent years, especially in cancer diagnosis. Combined with the terahertz imaging systems of transmission type and reflection type, a general review of its application in diagnosis of skin basal cell carcinoma, breast cancer, liver cancer and cervical cancer is provided. The achievements and the problems to be solved are also discussed, which made a beneficial exploration to the cancer diagnosis technology. Copyright © 2012 by TUMOR.
