What is a Thermogram? 10 hilariously insightful foreign words. A thermogram is a type of imaging test. It involves capturing infrared images of the heat that radiates off a person’s body and using the images to detect signs of medical conditions or injuries.Abnormalities are detected because of changes in heat production that can be noted via these images.owever, they are used in two different ways. A thermogram can be used to note heat changes in the breast, which indicates possible abnormalities. Mammograms, on the other hand, are used to detect a mass that’s developed after the cancerous cells have been in the body for quite some time.

Thermodynamic temperature Thermodynamic temperature is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is defined by the third law of thermodynamics in which the theoretically lowest temperature is the null or zero point.

Thermodynamics Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the material or system in question. The laws of thermodynamics are explained in terms of microscopic constituents by statistical mechanics.

What is Infrared Thermography? Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution.

Thermofax Thermo-Fax (very often Thermo fax) is 3M's trademarked name for a photocopying technology which was introduced in 1950. It was a form of thermographic printing and an example of a dry silver process. It was a significant advance as no chemicals were required, other than those contained in the copy paper itself. A thin sheet of heat sensitive copy paper was placed on the original document to be copied, and exposed to infrared energy.

thermometer Medical Definition of thermometer. : an instrument for determining temperature that usually consists either of a device providing a digital readout or of a glass bulb attached to a fine tube of glass with a numbered scale and containing a liquid (as mercury or colored alcohol) that is sealed in and rises and falls with changes of temperature.

Thermodynamic temperature The thermodynamic temperature is a measure of the average energy of the translational, vibrational, and rotational motions of matter 's particle constituents (molecules, atoms, and subatomic particles).he relationship of kinetic energy, mass, and velocity is given by the formula Ek = 1⁄2 mv 2. Accordingly, particles with one unit of mass moving at one unit of velocity have precisely the same kinetic energy, and precisely the same temperature, as those with four times the mass but half the velocity.

Thermometers: Understand the options Temporal artery thermometers. Temporal artery thermometers — often sold as forehead thermometers — use an infrared scanner to measure the temperature of the temporal artery in the forehead. The pros: Temporal artery thermometers can record a person's temperature quickly and are easily tolerated.

Thermocouples Using Thermocouples in Temperature Measurement. A thermocouple is a simple, robust and cost-effective temperature sensor used in a wide range of temperature measurement processes. It consists of two dissimilar metal wires, joined at one end. When properly configured, thermocouples can provide measurements over a wide range of temperatures.

Bright Hub Engineering Thermistors are semiconductor devices that are used to measure temperature. The name comes from a combination of the words resistor and thermal.Thermistors have an electrical resistance that is proportional to temperature. From a general physics course on electricity and magnetism, you may have learned that this is a property typical for all conductors.hermistors are temperature sensors that have a resistance proportional to their temperature. This property makes them useful for functioning as safety devices in circuits or as probes that physicians can use during surgery.

- A thermoluminescent dosimeter, or TLD, is a type of radiation dosimeter. A TLD measures ionizing radiation exposure by measuring the amount of visible light emitted from a crystal in the detector when the crystal is heated. The amount of light emitted is dependent upon the radiation exposure.

- The theoretical basis for thermometers is the zeroth law of thermodynamics which postulates that if you have three bodies, A, B and C, if A and B are at the same temperature, and B and C are at the same temperature then A and C are at the same temperature. B, of course, is the thermometer.

Thermocouple A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created.

Pyrometer A pyrometer is a type of remote-sensing thermometer used to measure the temperature of a surface.arious forms of pyrometers have historically existed. In the modern usage, it is a device that from a distance determines the temperature of a surface from the spectrum of the thermal radiation it emits, a process known as pyrometry and sometimes radiometry.

Thermocline From Wikipedia, the free encyclopedia. A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.
