About Thermal Imaging
How does thermal imaging work?
Thermal cameras are able to detect levels of infrared light that are invisible to the naked eye. The hotter the object, the more infrared radiation it produces. Thermal imaging converts the temperature differences into a visible picture we can see.
What can thermal images tell us?
Since thermal cameras detect heat, the images will show areas of the horse's body that are hotter than others. The horse should be symmetrical, meaning that the heat pattern on one side should be the same on the other side. Areas that display higher temperatures may indicate inflammation, injury, or increased blood flow.
Why should I get thermal images?
Thermal images are great for identifying areas of soreness, monitoring progress in a course of therapy, creating a baseline for any future problems, and evaluating a horse before purchase.
I. Full Body & Spine
The last two pictures (whole-spine views) are from after lunging at the walk, trot, and canter for a few minutes each way).
In the final image, it looks as though there is increased heat along her spine, on the left side hind and the right side shoulder.
II. Neck, Chest, & Shoulders
In the first picture (top left), the raised temperature at the top of the neck is probably attributed to her mane being on that side just before we took the picture. In the images of her right side, it looks like she may be tight on the area where her neck comes into her shoulder.
III. Front Legs
There's nothing here that's particularly noteworthy. Everything looks symmetrical for the most part.
Everything here looks fairly symmetrical. The last image was taken after Lily had been worked on a longe line very lightly. The increased heat behind her right elbow is to be expected.
Note the concentrated area of heat on the right side of her hindquarters. The neon green pixels indicate all areas that are within about 2 degrees of each other. On the left side, the heat seems to be spread more evenly. The difference in temperature between the two markers in the first and second image are due to the fact that the marker is not in the exact same place in each photo.
These 4 images were taken after 2 massages had taken place. There was 1 week between the first and second massage and 1 day between the 2nd massage and the time the images were taken. The right side of her hindquarters does seem to have a slightly higher temperature overall, although the hottest area is on the left side, right above the hock.
This last series of images (9) were taken after light lunging, which included walking, trotting, and cantering.
It seems like there might be a little more heat on the left side. This could be that she is compensating for pain on the right.
VI. Hind Legs
These images were taken prior to Lily being lunged. It looks like her hocks are cooler than the other parts of her legs on both sides, but maybe a little more so on the right.
These images were taken after light lunging. The heels/pastern area seem to be hotter on the right side than the left.
