Summary
Storing computed radiographic (CR) image plates above 40°C significantly increases dark noise, especially for AGFA systems. Keeping CR image plate storage temperatures below 35°C is recommended to maintain image quality.
Area of Science:
- Medical Imaging
- Radiography
Background:
- Computed radiographic (CR) image plates are sensitive to radiation, light, and heat.
- These factors can degrade image quality by introducing electronic noise.
Purpose of the Study:
- To investigate the impact of image plate storage temperature on dark noise.
- To assess temperature-related image quality degradation in CR systems.
Main Methods:
- CR image plates from Fuji and AGFA systems were stored at various temperatures for 5 hours.
- Dark noise was quantified by analyzing average pixel values and noise levels in processed images.
Main Results:
- Fuji CR plates showed increased dark noise above 40°C.
- AGFA CR plates exhibited increased noise at all tested temperatures.
Conclusions:
- CR image plate storage temperature significantly affects dark noise.
- Maintaining storage temperatures below 35°C is advised to minimize dark noise and preserve image quality.

Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...

67.3K
The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. Since heat is a form of energy, its SI unit is the joule (J). Another common unit of energy often used for heat is the calorie (cal), which is defined as the energy needed to change the temperature of 1 g of water by 1 °C, specifically between 14.5 °C and 15.5 °C, since the energy needed shows a slight temperature dependence. Another commonly used unit is...

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

The work done by a thermodynamic system depends not only on the initial and final states but also on the intermediate states—that is, on the path. Like work, when heat is added to a thermodynamic system, it undergoes a change of state, and the state attained depends on the path from the initial state to the final state. Consider an ideal gas cylinder fitted with a piston. When the cylinder is heated at a constant temperature, the gas molecules absorb energy and expand slowly in a...
