Problems solved by technology

However, the gynecological inspection mirror looks at the vaginal epidermis from the opening of the vaginal dilator, and the limited opening of the vaginal dilator results in a limited field of vision for looking at the vaginal wall.

Abstract

The invention relates to the imaging technical field and specifically relates to a terahertz imaging system. The terahertz imaging system comprises a terahertz emitter which is used for generating terahertz wave; a first receiver and a second receiver which are used for receiving reflected terahertz wave containing lesion tissues images; the first receiver and the second receiver transmit signals to a signal processor; the second receiver is positioned in the direction facing to the outlet of the vaginal dilator; the second receiver is electrically connected with a motor which can control the second receiver to rotate; an outer wall of the vaginal dilator is provided with a groove which is detachably provided with a liquid containing tube which may contain acetic acid. According to the invention, by means of the strong penetrating force of terahertz wave, the reflected waves of the terahertz waves passing through parts under detection is imaged so as to present pathologic changes at the parts under detection and to avoid misdiagnosis due to irradiation only on epidermis; after pathologic changes are detected from an imaged image of the reflected terahertz wave, liquid in the liquid containing tube is squeezed out to further present pathologic changes so as to avoid damages due to usage of the liquid on healthy parts under detection.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a terahertz imaging system. Background technique [0002] As a novel imaging method, terahertz imaging has been favored in medical applications in recent years. Terahertz waves have better penetration ability than infrared light and lower photon energy than X-rays, so they are useful in living body detection. Great advantage. The advantage of terahertz waves over other electromagnetic waves is that terahertz waves are highly sensitive to interstitial water, harmless to the human body, and have high spatial resolution, up to tens of microns, and can clearly show the interior of diseased tissues In the image, the lesions of some diseased tissues can be clearly seen, which is convenient for doctors to diagnose. [0003] However, the existing terahertz imaging system is only used in the detection of brain diseases in clinical medicine, and cannot make good use of the advantages of...
