What type of current is required for proper operation of the x-ray tube? - Direct Electromagnetic radiation travels: - In waves along a straight path Frequency is defined as: - The number of waves passing a point per unit time Wavelength is defined as the distance from: - Peak to peak of the wave Wavelength and frequency are: - Inversely proportional to each other The x-ray beam changes as it travels through the patient by a process called: - Attenuation The intensity of radiation is inver...

high potential difference - Required to move the electron stream rapidly across the X-ray tube/ VOLTAGE Unit of potential difference - Volts patient dose: - calculated as ESE (entrance skin exposure) Transformer that has more windings on primary side: - step-down Factors that affect xray QUALITY: - kvp & filtration How does scatter rad fog reduce visability of detail in image? - it decreases contrast Contrast is directly influenced by: - fog & collimation What minimizes shap...

X-rays are produced by: characteristic and bremsstrahlung interactions When filament electrons enter the anode target, they interact with: Outer shell electrons of tungsten atoms Brainpower Read More When a filament electron knocks out a K shell electron from the tungsten atom, it leads to: A characteristic x-ray photon The energy of the characteristic x-ray photon depends on: a.) the binding energy of the inner-shell electron b.) the energy level of the filament electron c.) the shel...
