X-Ray Physics and Technology Quiz

A measure of how sensitive a screen is to x-rays, affecting how quickly an image is formed.

The sharpness and clarity of the image produced, influenced by factors like screen speed and grid ratio.

November 8, 1895, the date Wilhelm Conrad Röntgen discovered X-rays.

Gamma rays have short wavelengths, making them higher-energy and more penetrating.

Random variations in the image due to the stochastic nature of X-ray interaction with matter.

Differences in X-ray absorption by tissues of varying densities.

The difference between the darkest and lightest areas of a radiographic image.

Sharpness or clarity of detail in an image.

The anode and cathode are critical parts of the X-ray tube.

Pyrex glass is used in X-ray tubes to withstand the intense heat generated.

The reduction in radiation intensity as it passes through materials.

A device that allows control of x-ray intensity and energy.

A type of vacuum tube used in x-ray machines.

Reduction in x-ray intensity as it passes through material.

The material used at the target in an x-ray tube.

Common anode material in x-ray tubes due to heat resistance.

Part of an x-ray tube that can withstand more heat.

Relationship between light transmitted and radiograph.

A moving grid used to reduce scatter radiation.

Ability to distinguish separate objects in an image.

Distance between x-ray source and the image receptor.

X-ray technique using low kilovoltage.

Restricting the x-ray beam to the area of interest

Movement of the patient during the exposure.

Ratio of the height of the grid to the distance between the grid's lead strips

Product of milliamperage and exposure time

Used to focus the x-ray beam.

Higher radiation exposure to the patient.

Narrow range of exposure factors for acceptable results.

Factors like distance, kVp, mAs, and HVL, the radiographer can adjust to affect image quality and patient dose.

Kilovoltage Peak, controls the energy of x-ray photons.

milliAmpere-seconds, controls the quantity of x-rays produced.

Point of overexposure on an image.

Number of lead strips per unit length (e.g., per inch or cm).

Film's darkness or blackness.

Difference in densities in an image.

Enlargement of the image.

Inverted image.

Unclear image.

Measures image darkness.

More intensity (quantity) of x-ray photons, leading to increased image density.
