2. WHAT “ THERMOGRAPHY” MEANS?
• Thermography or Thermology is the medical science that derives diagnostic indications
from highly detailed and sensitive infrared images of the human body.
• Also referred to as:
Infra-Red Imaging
Tele-Thermology
Utilizes high resolution & sensitive camera.
GAURAV R. DESHMUKH
3. • Thermography is used for early
pre-clinical diagnosis and control
during treatment of homeostatic
imbalances.
• Uses digital imaging called as
(digital infrared thermal imaging - DITI ).
• Non-Invasive, non-contact tool.
• Uses heat of the body as
the measurement parameter.

4. COMPONENTS INVOLVED:
• Uses only 2 parts:
1). The IR camera &
2). Computer.
Monitors are high-resolution
full colour PC based systems
therefore can store thousands
of images.

10. THERMOGRAPHIC CAMERA
• Their resolution is considerably lower than of optical cameras, mostly only 160x120 or
320x240 pixels.
• 1 °C difference at the scene induces just a 0.03 °C difference at the sensor.
--Types
Cooled infrared detectors
Uncooled infrared detectors

11. ADVANTAGES OF THERMOGRAPHY
• It shows a visual picture so temperatures
over a large area can be compared.
• It is capable of catching moving targets
in real time.
• It is able to find deteriorating, i.e.,
higher temperature components prior
to their failure.
• It is a non-destructive test method
• It can be used to detect objects in dark areas.

12. LIMITATIONS OF THERMOGRAPHY
1).Quality cameras often have a high price range.
2).Images can be difficult to interpret accurately when based
upon certain objects, specifically objects with erratic
temperatures.
3).Most cameras have ±2% accuracy or worse in measurement.
4).Only able to directly detect surface temperatures
5).Condition of work, depending of the case, can be drastic.
