Anatomical and functional information of the structures of interest is the basis of radiology interpretation. Many diagnosis of some facial diseases may be done through medical imaging techniques, however the most conventional present lack of information in analyzing physiological functional aspects such as microcirculation and autonomous nervous s...

... examiner had the participant sit on the examination chair, and asked her to relax her facial muscles, keeping her teeth apart. This first position referred to the static thermal image. Then, all subjects underwent to a mechanical provocation test for 2 minutes (stimulation by chewing a gum in the first day and vibration stimulation, fig. 1, in the second day) and a new image registration was taken. After this, a new vascular provocation test was performed for 1 minute using a cold facial mask ( fig. 2) [21][22][23][24]. Lastly, several frontal series of thermal images were taken every minute in 10 minutes interval to evaluate changes in the pattern of facial micro ...

... mean temperatures for asymptomatic and symptomatic subjects were calculated for all 6 ROIs (p > 0.05) assessed over the trochlear artery and vein (ROIs 1, 2), supraorbital artery and vein (ROIs 3, 4) and facial artery and vein (ROIs 5, 6). When the chewing and vibration tests were compared, they are not statistically significant even when comparing between groups (symptomatic and asymptomatic), sides (left and right) and tests (chewing and vibration tests) (p > 0.05, Fig. 4). ...

Thermal imaging is of value to medical professionals because of its low risk and non-invasive properties. While thermal imaging has been explored in the area of pressure ulcers, many relevant papers address existing pressure ulcers and few address the prevention of pressure ulcers. This paper aims to examine the potential of thermal imaging in the prevention of pressure ulcers by extracting temperature-based and region-based measurements from thermal images and quantifying thermal patterns. A subject was asked to press on a pressure sensor mat at two specified intensities, and a series of thermal images were taken before and after to track thermal behaviour. These images were subjected to standard image processing techniques before temperature specific contour and area measurements were extracted as well as region specific intensity and weighted centroid measurements. Results indicated that the contour and area measurements were able to capture the temperature pattern of the whole hand, while the intensity measurements were able to indicate region specific thermal patterns. These results suggest that the extraction of measurements from a series of thermal images can capture and quantify visually identifiable thermal patterns of the hand over time. These findings will be expanded upon in future work by further examining different measurements, sharper images, different equipment and the involvement of elderly patients. While future collection of patient data is expected to yield different thermal patterns, this paper has demonstrated recognition and quantification of a pattern, regardless of the pattern itself.
