Description
Technical field
The invention belongs to the Infrared Thermography Technology field, be specifically related to a kind of infrared detection system with Radix Rumicis infrared thermal imagery camera lens.
Background technology
Infrared Thermography Technology is applied to existing more than the 40 year history of medical domain, and since British physician Lawson in 1956 was with the Infrared Thermography Technology diagnosing mammary cancer, medical infrared thermography technique progressively received people's concern.In recent years, along with photoelectric technology, Computer Multimedia Technology, the especially development of semiconductor technology, make resolution capability, the definition of thermal imaging system reach the level of clinical demand, therefore, the application of medical infrared thermal imaging system is in widespread attention gradually, becomes new in the world study hotspot.
The half body image-forming range of present diagnostic thermograph is 4.5～5.0m, adds staff's operating board, so that the thermal imagery chamber needs the space more than 15 square metres at least, brings some inconvenience for carrying out the infrared thermal imagery operation.
The IR thermal imaging inspection mode of carrying out in the medical treatment all is that to allow the patient stand in thermal imagery indoor and over against thermal infrared imager, then by the doctor patient is carried out thermal imaging and detects.In testing process, can not independently carry out thermal imaging for some patients that can't stand and detect, can cause thermal imaging inaccurate owing to other people temperature effect and assist assistance in by other people; Carry out the patient that thermal imaging detects even can stand, may be owing to neuralgia, local pain etc. produce part or whole-body muscle spasm, the heat that muscle spasm produces also can affect the degree of accuracy that thermal imaging detects.
Wherein, for mastopathy, female patient especially, more very be the mastopathy that still only is in the changes of function stage for pathological changes because structural change is small, require infraredly as instrument mammary gland tumor to be carried out highly sensitive detection.Yet because female patient stands when detecting, breast will be subject to local compression, cause infrared thermal imaging inaccurate, may cause the mistaken diagnosis of focus and delay diagnosis.
In addition, present infrared thermal imaging background fails to obtain standardization, and particular problem shows: a. is because imaging ambient temperature disunity, fail standardization, its image is comparatively not objective, such as 37 ℃ of body temperature, 35 ℃ of backgrounds, perhaps 37 ℃ of body temperature, 25 ℃ of backgrounds then can't compare; B. ambient temperature is all once inadequate, can not standardization, and can not correct comparison; C. lateral airflow can affect the image correctness; D. do not adopt black matrix to proofread and correct at any time, so still there is drift error in thermal infrared imager mensuration temperature value itself; E. camera angle is nonstandard, and the patient rotates inconvenience, can not the correct comparison result.
In sum, in medical infrared thermography is used, extensively there are problems at present, therefore are necessary to provide a cover to make things convenient for infrared imaging to detect and the high infrared detection system of imaging accuracy.
Summary of the invention
For above-mentioned weak point of the prior art, the present invention aims to provide a kind of infrared detection system with Radix Rumicis infrared thermal imagery camera lens, and the patient can directly lie low and carry out infrared detection on the diagnostic bed body, and is easy to detect and the result is more accurate.
