Description
Technical field
The invention belongs to 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 is with Infrared Thermography Technology diagnosing mammary cancer, medical infrared thermography technique progressively receives 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 current diagnostic thermograph is 4.5～5.0m, adds staff's operating board, makes thermal imagery chamber at least need 15 square metres of above spaces, brings some inconvenience for carrying out infrared thermal imagery operation.
The IR thermal imaging inspection mode of carrying out in medical treatment is all that to allow patient stand on thermal imagery indoor and just to thermal infrared imager, then by doctor, patient is carried out to thermal imaging detection.In testing process, the patient that cannot stand for some can not independently carry out thermal imaging detection, can cause thermal imaging inaccurate due to other people temperature impact and assist assistance in by other people; Carry out the patient of thermal imaging detection even if can stand, may produce part or whole-body muscle spasm due to neuralgia, local pain etc., the heat that muscle spasm produces also can affect the degree of accuracy that thermal imaging detects.
Wherein, for mastopathy, especially female patient, more very be for the still mastopathy in the changes of function stage only of pathological changes, because structural change is small, require infrared image instrument to carry out highly sensitive detection to mammary gland tumor.But because female patient is stood while 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, current infrared thermal imaging background fails to obtain standardization, and particular problem shows: a. is due to imaging ambient temperature disunity, fail standardization, its image is comparatively not objective, as 37 DEG C of body temperature, 35 DEG C of backgrounds, or 37 DEG C of body temperature, 25 DEG C of backgrounds, cannot compare; B. ambient temperature is all once inadequate, can not standardization, and can not correct comparison; C. lateral airflow can affect image correctness; D. do not adopt black matrix to proofread and correct at any time, therefore thermal infrared imager itself is measured temperature value and is still had drift error; E. camera angle is nonstandard, and patient rotates inconvenience, can not correct comparison result.
In sum, in medical infrared thermography application, extensively there are problems at present, be therefore necessary to provide a set of infrared imaging that facilitates to detect and the high infrared detection system of imaging accuracy.
