Abstract
The utility model requests to protect a galactophore infrared double-waveband camera. The camera comprises a near infrared camera system and a far infrared camera system, which are quipped in the same casing. A spectroscope is provided in the light input path of the camera and divides the light into a far infrared light into the far infrared camera system and a near infrared light completely reflected into the near infrared camera system. Meanwhile, a coaxial correction system is equipped between the two camera systems. As the galactophore infrared double-waveband camera uses the near infrared and far infrared wave lengths at the same time, a thermal radiation field and a low oxygen ferrohemoglobin distribution field can be collected at the same time to make two images of two information varieties overlap, and different information can be reintegrated with the computer technology and make gradable judgments. The examination equipment is safe for the human body and causes no damages. Moreover, the equipment is characterized in that the equipment is highly sensitive and quite economical.
Description
Technical field
The utility model relates to mammary gland infrared detection technology field, is specifically related to the two waveband cam device.
Background technology
China's mammary glands in women cancer morbidity rose to first malignant tumour of women after 1977, therefore need actively develop the large tracts of land generaI investigation.Present American-European continent developed country mostly adopts Mammography or the generaI investigation of CR technology.Though this method breast cancer recall rate is higher,, efficient is low, consumptive material is high, human body is had injury, and the funds spending is big.During mammary gland generation canceration, occur in mammary gland tip catheter leaflet unit (Terminal Ductal Lobular Units)--TDLU at first, all be confined to millimeter with between interior TDLU tissue from atypical hyperplasia → carcinoma in situ → evolution process such as micro-infiltrating carcinoma, its volume ∠ 1MM, image checks such as general X line, B ultrasonic need possess certain density resolution, only lump occurs and reach just meeting video picture more than the 2mm later in canceration, so leak early lesion easily, so research breast cancer generaI investigation new method, new technology, new equipment are the task of top priority.
Existing near-infrared mammary instrument is to adopt the near infrared light inspection method, is to utilize near infrared light when the transmission breast, and the hypoxemia haemoglobin absorbs the near infrared light effect in the blood of human body, forms image information source.But the thermal radiation field that is produced when tumour is taken place, promptly functional variation then can't be collected simultaneously, and these biochemical changes are to express canceration initial stage important information, therefore adopt single near-infrared mammary instrument inspection still to have the problem of omission.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, a kind of mammary gland infrared double-waveband camera is provided, can be simultaneously, synchronously, take mammary gland temperature field and haemoglobin distribution field with the visual field, to reach the various information of comprehensive collection, for analysis-by-synthesis provides condition, improve the susceptibility of breast cancer detection and early examine rate.
The technical solution of the utility model is as follows:
A kind of mammary gland infrared double-waveband camera, it has a near infrared camera system, a far infrared camera system, and twin-lens is contained in the shell jointly, is integrated.The place ahead of its mid and far infrared camera system is provided with spectroscope, and the place ahead of near infrared camera system is provided with completely reflecting mirror.Spectroscope is positioned on the light inlet light path of camera, and the place ahead is over against incidence hole, and the light that spectroscope is accepted is divided into two-way, and one the tunnel is far red light, enters the far infrared camera system, and another road is a near infrared light, enters the near infrared camera system through the completely reflecting mirror reflection; Two camera systems one of them and housing are fixed, and another and housing flexibly connect, and coaxial correction system is set between two camera systems, to be implemented in same visual field, fixing position, absorb the infrared ray information of two kinds of different-wavebands synchronously.
Wherein, the far infrared camera system adopts focus planardetector, realizes the moment shooting, and reduces the volume of camera system.The near infrared camera system adopts has the camera system of adjustable visual field camera lens, adjustable to reach the visual field, makes far away, near infrared camera system can be transferred to same visual field easily.In addition, dustproof lens are installed also on the incidence hole on the housing, so that protect camera system better.
The principle of work of this camera is such: incident light arrives spectroscope by dustproof lens, be divided into far red light and near infrared light two-way by spectroscope, far red light enters the far infrared camera system, near infrared light enters the near infrared camera system, the far infrared camera system is obtained the mammary gland temperature distribution information, and the near infrared camera system is obtained the haemoglobin distributed intelligence.In when shooting, by coaxial correction system make far, the near infrared camera system is transferred to coaxial state.
As seen from the above technical solution, this mammary gland infrared double-waveband camera has adopted near infrared and two kinds of wavelength of far infrared simultaneously.Can collect thermal radiation field and hypoxemia haemoglobin distribution field simultaneously, the dual image of two kinds of information is overlapped.So that various information are reintegrated by computer technology, make classification and judge, can improve the susceptibility of breast cancer detection and early examine rate, have human body safety, not damaged, highly sensitive, the economic dispatch characteristics are more suitable for doing large tracts of land women crowd's breast screening.
