Abstract

Provided is an intervention type in-vivo real-time tumor imaging method and system. The imaging method comprises the steps that the polarization directions of terahertz and infrared source emergent light waves are adjusted, the light waves are conducted to the tissue to be detected through an array optical-fiber bundle, signals reflected by the tissue are converted into vertically polarized waves and then enter a detector for imaging in an incidence mode. The imaging system comprises a terahertz and infrared source, a terahertz detector, a reshaping unit, a polarization unit, a polarization conversion unit and an intervention unit. The system works in a terahertz and infrared frequency band, can perform tumor diagnosis in the human body in real time, has more advantages compared with X-ray, CT examination and other technologies, is high in spatial resolution, and has more advantages than a pathological biopsy technology in rapid, accurate and noninvasive characteristics. The intervention type in-vivo real-time tumor imaging method is safer, more accurate, quicker and more convenient and has the good application prospect in tumor diagnosis.

Description

technical field

[0001] The invention belongs to the field of tumor diagnosis research, and in particular relates to an interventional in vivo real-time tumor imaging system and method. Background technique

[0002] Malignant tumors are major diseases that seriously threaten human health. The incidence of malignant tumors in China has ranked first in the world, and it has become the main cause of death in my country in recent years. Continuously improving the diagnostic level of tumors is of great significance to improving the curative effect, prognosis and quality of life of cancer patients. The main methods widely used in clinical diagnosis of tumors are imaging examinations and pathological biopsy techniques, but these methods have certain limitations.

[0003] The most commonly used imaging examination methods in clinical practice include X-ray, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET) and ultrasound (US). Even with ...
