Introduction
Objective
Workflow
Methodology
Conclusion
References
Neuropathy means
 damage to nerves
in the peripheral nervous system, and
so affects nerves outside of the brain and spinal
cord –
 it does not include nerve damage in the central
nervous system
Peripheral neuropathy, also called
distal symmetric neuropathy or
sensorimotor neuropathy,
is nerve damage in the arms and legs.
Peripheral neuropathy is the most common form of
 diabetic neuropathy.
In that your feet and legs are often affected first,
followed by your hands and arms.
Possible
signs and
symptoms of
peripheral neuropathy include
Numbness or
reduced ability to feel pain or
changes in temperature,
especially in your feet and toes.
Thermography is a
noninvasive imaging technique that is useful
to measure temperature distribution in organs and
tissues
Thermal camera work on
Infrared (IR) and
it is not at all harmful for our body
For detecting the diabetic ulcer
we design the one model
 in that
we calculate the temperature and
accordingly we decide the subject is
normal or
have diabetes or
it have ulcer problem

According to WHO literature
Temperature with neuropathy is 32–35 °C and
Temperature without neuropathy 27–30 °C.

The temperature variation between
 corresponding regions in both feet
usually does not vary beyond 1°C;
a difference greater than 2.2°C
is considered as abnormal Calculating
The temperature difference between the left and
the right foot,
taking 2.2 ◦C as a clinically relevant
difference,
(pre-)signs of ulceration can be automatically
detected.
Thermography is a noninvasive imaging technique ,that is
useful to
measure temperature distribution in organs and tissues.
 And it is useful tools in the medical field applied to the
study of diseases such as diabetes.
Using the thermal images we can
detect the abnormalities of diabetic feet .
And also useful for early detecting the ulcer problem.
