Thermography in Human Medicine

Infrared camera systems make imaging of body temperature possible

The body temperature is an essential indicator for people’s health, and thus, much attention has been given to its determination. Measuring temperature with infrared camera systems comes with particular advantages for doctors as well for patients. As a non-contact and non-invasive diagnostic procedure, thermography is patient-friendly and does not only provide punctual temperature measurement but gives a detailed image of patients’ body temperature distribution.

Thermography is a flexible and budget-friendly diagnostic method

Since multiple disease patterns can be diagnosed through information on the body´s  temperature distribution, thermography represents a highly flexible procedure which is, in comparison to other processes in medical engineering, budget-friendly. Thermographic diagnoses are often connected with an irritation of the body. Thus, on applying regulation thermography, affected body parts are exposed to a cold stimulus. Healthy body regions and organs balance out this intervention on the body-heat in another way than unhealthy ones. This process is, for instance, typical for the early detection of breast cancer. However, also the correct positioning of an acupuncture needle can be controlled by an infrared camera since heat development might differentiate depending on whether the needle has been placed on the right spot or not.

Thermography for Health

With the use of a thermometer only an indication of a spot temperature can be obtained. Infrared thermography provides the complete picture, non-invasive temperature measurement of the complete body part.

Thermal Resolution of Infrared Camera Systems Determines a Successful Analysis

On applying thermography for medical diagnosis, a question arises in terms of thermal resolution, which is the infrared camera’s ability to detect smallest differences in temperature. Minimal differences in degrees Celsius (hundredth of a degree) can be a crucial factor for a successful diagnosis. InfraTec provides with its VarioCAM® series highest thermal resolutions in the uncooled infrared camera segment. These infrared camera systems can be equipped with close-up lenses in order to analyse smallest body regions in detail. Thus, skin reactions like perspiration or temperature changes of the eyes are observable in an accurate way with the help of an infrared camera.

    10 GigE Interface for a Strong Increase in Output

    The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.

    Different 10 GigE fiber SFP+ transceivers allow transmission ranges of up to ten kilometers with the same low sensitivity to electromagnetic interference. A corresponding standard SFP ensures backward compatibility with the conventional GigE interface. This combination allows the ease of use of the cameras with the 10 Gigabit Ethernet interface in existing systems - though at a reduced transmission rate.

    Motor Focus for ImageIR® Full Lenses – More Comfort

    All interchangeable standard lens systems of the ImageIR® series can be combined with a motor focus unit, which is controlled by the camera operating software. It enables precise, remote and fast focusing. In addition, an autofocus function is available which operates reliably even with low image contrasts.

    Further information about permanent autofocus

    Permanent Autofocus

    Constantly changing object scenes require manual or automatic refocusing. The integrated permanent autofocus function makes this task easier. In the case of a change of scene, the camera automatically applies the optimum focus setting quickly and precisely. The completely innovative, very powerful autofocus system is laser-based and works extremely reliably. Even under unfavourable environmental conditions, such as poor lighting conditions, darkness or low thermal contrasts on the measuring object, this function provides exactly focused thermal images.

  • High-performance Full Optics

    High quality precision lenses allow the adaptation of the image geometry to almost every measuring situation. Its performance parameters are calibrated with respect to functionality, quality and flexible application. Due to proper IR-transparent lens materials and high-precision antireflexion coating, the lenses are optimised for different spectral ranges.

    Geometrical Resolution – Efficient Analysis of Complex Assemblies

    InfraTec's infrared cameras with cooled and uncooled detectors have native resolutions up to (1,920 × 1,536) IR pixels. Spatially high-resolution thermograms ensure that components and assemblies are imaged down to the smallest detail and thus defects can be reliably detected and precisely localised.

  • InfraTec thermography - Thermal resolution

    Thermal Resolution – Determination of Differences of Only a Few Millikelvin

    For detection of small temperature changes InfraTec's infrared cameras offer thermal resolutions up to < 15 mK in real-time operation. By using the Lock-in Thermography method it is possible to further increase this resolution significantly. For this purpose test objects are periodically excited and non-destructively examined for defects and irregularities.

Thermography in Veterinary Medicine

Various Disease Patterns are Detectable by Means of Thermography

Medical examinations of animals can be carried out in an efficient way by applying infrared camera systems. Animal’s body temperature can indicate multiple health problems. These may affect the animal itself, as for instance diseases of the udder or hoof, or they result from animal husbandry, as it is in the case of an incorrect application of saddles causing pressure points and, following, local overheating on horses. Inflammations and lameness are further problems which can be detected with the help of thermography.

Infrared Camera’s Compactness and Small Size allows its Flexible Application

In particular, the application of infrared camera systems is of interest due to their high mobility and – in contrast to many other procedures of veterinary medical engineering – can, therefore, be taken into stables. InfraTec’s camera series VarioCAM® impresses especially with their small size and low weight. Moreover, thermography is a non-contact measurement process which ensures that animals are not unnecessarily provoked.
