Assessing Body Temperature - Temporal Artery

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...

Temperature and Thermal Equilibrium

Temperature and Thermal Equilibrium

Heat and temperature are essential concepts for everyone every day. The study of heat and temperature is part of an area of physics known as thermodynamics. It is not always easy to distinguish heat and temperature.
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...

Temperature Dependent Deformation

Temperature Dependent Deformation

In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added together...

Equipments Used to Measure Body Temperature

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Assessing Body Temperature - Tympanic membrane

Assessing Body Temperature - Tympanic membrane

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Area of Science:

Biomedical Engineering
Medical Imaging
Therapeutic Monitoring

Background:

Thermal properties of biological tissues are crucial for understanding tumor angiogenesis and guiding thermal therapies.
Accurate, noninvasive methods are needed to map tissue thermal parameters for improved treatment outcomes.

Purpose of the Study:

To introduce a novel noninvasive technique, temperature-change-based thermal tomography (TTT), for mapping thermal parameters in biological tissues.
To overcome limitations of existing methods by not requiring spatially invariant steady-state temperatures or absolute temperature mapping.

Main Methods:

Utilized relative temperature mapping with magnetic resonance imaging (MRI) to develop TTT.
Employed numerical simulations to validate the TTT approach in a breast phantom model.

Main Results:

TTT successfully depicted a simulated (9 mm)^3 tumor within a breast phantom.
The method demonstrated reliability with a moderate temperature mapping accuracy of 0.5 degrees C.

Conclusions:

TTT offers a physiologically realistic and technically convenient approach for noninvasive thermal parameter mapping.
This technique shows promise for enhancing the design and monitoring of thermal therapies, particularly in oncology.
