Description

Wide-angle infrared camera and infrared detection system containing the same

Technical field

The invention belongs to the field of infrared thermal imaging technology, and particularly relates to a medical wide-angle infrared thermal imager, and also relates to an infrared detection system containing the wide-angle infrared thermal imager.

Background technique

Infrared thermal imaging technology has been applied to the medical field for more than 40 years. Since the British doctor Lawson used infrared thermal imaging technology to diagnose breast cancer in 1956, medical infrared thermal imaging technology has gradually attracted people's attention. In recent years, with the development of optoelectronic technology, computer multimedia technology, especially semiconductor technology, the resolution and clarity of thermal imaging cameras have reached the level of clinical demand. Therefore, the application of medical infrared imaging cameras has gradually received extensive attention. It has become a new research hotspot in the world. At present, the half-length imaging distance of the medical thermal imager is 4.5 to 5.0 m, and the staff operating table makes the thermal image room require at least 15 square meters of space, which brings certain inconvenience to the infrared thermal image operation. In addition, due to the large working space, the room temperature control and interference airflow control accuracy is difficult, which is not conducive to cost saving. Medically performed infrared thermal image detection methods allow the patient to stand in the thermal image chamber and face the infrared camera, and then the patient performs thermal imaging detection on the patient. During the detection process, some patients who are unable to stand will not be able to independently perform thermal imaging detection, while assisted by others will cause thermal imaging inaccuracy due to the influence of other people's temperature; even patients who can stand for thermal imaging detection may be due to nerves. Pain, local pain, etc. produce local or systemic muscle spasms, and the heat generated by muscle spasm also affects the accuracy of thermal imaging detection. Among them, for breast diseases, especially in female patients, it is even more so that the breast disease is only in the stage of functional changes. Because of the small structural changes, the infrared imager is required to detect the breast mass with high sensitivity. However, when the female patient stands up for testing, the breast will be partially compressed, resulting in inaccurate infrared thermography, which may lead to misdiagnosis of the lesion and delay diagnosis. In addition, the current infrared thermal imaging background has not been standardized. The specific problems are as follows: a. Because the imaging background temperature is not uniform, it cannot be standardized, and its image is not objective, such as body temperature 37 ° C, background 35 ° C, or body temperature 37 °C, background 25 °C, can not be compared; b. background temperature is not enough, can not be standardized, can not be correctly compared; c. lateral airflow will affect the correctness of the image; d. no black body correction at any time, so the thermal imaging camera itself There is still drift error in the measured temperature value; e. The camera angle is not standard, the patient is not convenient to rotate, and the result cannot be correctly compared. In summary, there are currently many problems in medical infrared thermal imaging applications. Therefore, it is necessary to provide an infrared thermal imaging device that is convenient to operate, and to design a detection system that is convenient for infrared imaging detection and has high imaging accuracy.
