Medical Thermography

see the body with different eyes

Medical thermography, also known as thermal imaging or digital infrared thermal imaging (DITI), is a non-invasive diagnostic technique that uses an infrared camera to produce images that show variations in temperature on the surface of the skin. The images can help identify areas of increased heat, which may be indicative of inflammation, injury, or other underlying conditions.

Thermography is often used in combination with other diagnostic tools, such as X-rays, MRIs, or ultrasound, to provide a more comprehensive picture of a patient's health. It is commonly used to diagnose conditions such as musculoskeletal injuries, breast cancer, cardiovascular disease, and neurological disorders.

It's important to note that thermography is not a substitute for other diagnostic techniques, and it should not be used to replace conventional medical testing. However, it can provide valuable information to healthcare providers in the diagnostic process.

In conclusion, medical thermography is a useful tool in the diagnostic process, but it should be used in conjunction with other diagnostic techniques to provide the most comprehensive understanding of a patient's health.


Medical Thermography Applications include:

Musculoskeletal conditions: Thermography can be used to diagnose and monitor conditions such as arthritis, back pain, carpal tunnel syndrome, and other musculoskeletal conditions.

Breast health: Medical thermography is commonly used as an adjunctive tool in the detection and monitoring of breast cancer. It can help identify areas of increased heat, which may indicate the presence of cancer or other breast health issues.

Cardiovascular health: Thermography can be used to assess blood flow and detect areas of decreased circulation, which may indicate a risk for cardiovascular disease.

Neurological disorders: Thermography can be used to diagnose conditions such as migraines, headaches, and neck pain, as well as to monitor the progress of conditions such as multiple sclerosis.

Pain management: Thermography can be used to monitor the effectiveness of pain management treatments and to identify areas of pain and inflammation.

Dental health: Thermography can be used to diagnose and monitor conditions such as temporomandibular joint (TMJ) syndrome, jaw pain, and other dental health issues.

Skin conditions: Thermography can be used to diagnose and monitor conditions such as eczema, psoriasis, and other skin conditions.

It's important to note that medical thermography is not a replacement for other diagnostic techniques, such as X-rays, MRIs, or biopsies, and it should be used in combination with these techniques for the most comprehensive understanding of a patient's health.

Why fever measurement with thermography?

An important indicator for an infection is increased body temperature (compared to other people in the immediate surroundings), generally known as fever. Thermography is the ideal method for scanning not just individuals, but also large flows of people. To do this, the temperature at the inner corner of the eye is measured, and an alarm triggered if it deviates. This allows persons with increased body temperature to be identified quickly and reliably, and to be isolated for more exact testing.

Built-in battery, it can work for 8 hours, and can be equipped with support frame for temporary control on site.

Temperature Screening Action

When the device detects someone into the monitored area, voice guidance is heard " Please go to the temperature measuring point for temperature measurement ".
2. When the body pass the temperature area, within 1 meter distance and 30 degrees of the camera, the device will measure the temperature and determine it in 0.5 seconds.
3. According to the temperature data, when temperature is normal, the device indicates that the body temperature is normal and instantly returns to normal temperature measuring state.
4. According to the temperature data, when the body temperature exceeds 37.3, the device will immediately enter into the alert mode, trigger the built-in alarm siren, voice reminding temperature abnormality, and push to the terminal synchronously.
5. Each temperature measurement process is completed in 0.5-second sensorless multipoint, the device synchronously displays the real-time terminal, and synchronously stores the temperature superposition chart, temperature data and temperature measurement video.
6. The temperature data are calculated in real time and displayed synchronously according to daily statistics.
