ABSTRACT In the present study, image reconstruction methods are applied in active dynamic thermography (ADT) to visualize the superficial blood vessel with high contrast. ADT is performed on the left forearm of a human subject by applying cooling based external thermal stimulation. Both non-parametrized, viz. sequence image, sequentially subtracted image, Discrete Fourier Transformation (phase and amplitude image), and Thermographic Signal Reconstruction (TSR), and parametrized, viz. Tau time… 
Quantitative Analysis of Real-Time Infrared Thermography for the Assessment of Lumbar Sympathetic Blocks: A Preliminary Study
The preliminary study showed that the measurement of skin temperature in real time by infrared thermography is valuable for assessing the success of lumbar sympathetic blocks in patients with complex regional pain syndrome affecting the lower limbs.

The Automatization of a New Thermography Method Using Invasive Nociceptive Stimulation to Confirm an Autonomic Phenomenon within a Trigger Point Referred Pain Zone
This study examined the MATLAB software utility for the objective stratification of low back pain patients using the Minimally Invasive Procedure (MIP) and the two diagnostic MIP parameters were: average temperature (ΔTavr) and autonomic referred pain (AURP).

This study has attempted to increase the interpretation of breast thermography by using thermal recovery and sequential and subtraction thermography, hoping that even small tumors with negative steady-state thermography may appear in dynamic thermography.
Active dynamic thermography method for TRAM flap blood perfusion mapping in breast reconstruction
The new method of the transverse rectus abdominis musculocutaneous flap blood perfusion mapping based on the active dynamic thermography is presented, showing that this is potentially an objective and effective method of skin flap perfusion assessment that can be performed in the operating room.
Thermal Parametric Imaging in the Evaluation of Skin Burn Depth
The results indicate that it is possible to distinguish objectively and quantitatively burns which will heal spontaneously within three weeks of infliction and which should be treated conservatively from those which need surgery because they will not heal within this period.
Lockin thermography for imaging of modulated flow in blood vessels
This paper shows how lockin thermography can be modified in order to meet medical needs in the visualization of functionality of blood vessels to provide infonmation about the blood flow in the vessels.
