Increasing _______ ________ ________ increases beam attenuation by absorption of scattering

created by passing an x-ray beam through the patient and interacting with an image receptor such as an imaging plate in computed radiography.

more likely to occur in tissues with higher anatomic number

If differential absorption is increased there will be: - ________ kVp - ________ image contrast - ________ patient dose

called when some x-ray photons are absorbed as the energy of the primary beam is deposited within the atoms comprising the tissue

comes from the patient and is a cause of occupational radiation

reduction in the energy or number of photons in the primary beam

does not reach the image receptor as this interaction is absorbed by the body. Represents anatomy with high x-ray absorption characteristics are also called radiopaque (meaning they appear white in the image)

this produce the light areas in the radiograph

called as the x-ray beam passes through anatomic tissue, it loses some of its energy

Increased _____ ______ ______ (energy) decreases beam attenuation

Reducers of Scatter Radiation on Image

An ejected electron which also quickly loses energy by interacting with nearby tissues

3 ways to create a radiograph image by differential absorption

The combination of absorption and transmission creates an image that represents the ________ _______

The variations in absorption and transmission of the _____ _____ structurally REPRESENT the ANATOMIC AREA of interest.

______ _______ ______ more likely to be transmitted through anatomic tissue without interacting with the tissue's anatomic structures.

occurs when the incoming x-ray photon has enough energy to remove an inner-shell electron

term used when the incoming x-ray photon passes through the anatomic part without any interaction with the anatomic structures

what happens when xray beam quality is increased attenuation - absorption - transmission -

process whereby some of the x-ray beam is absorbed in the tissue and some passes through the anatomic part and is received by the image receptor.

occurs because of Compton Scattering, Photoelectric Effect, and x-rays transmitted through the patient

what happens when tissue thickness is increased attenuation - absorption - transmission -

Results from Compton effect (incoming photons in the diagnostic range loses energy during interactions with the atoms comprising the tissue

Refers to the compactness of the anatomic particles comprising an anatomic part.

Contributes no useful information to the image results to image noise

Three important types of x-rays to make a radiograph 1. scattered by ______ _______ 2. Absorbed _________ 3. transmitted through _____ without interaction

produces image fog and compromises the image if it strikes the image receptor.

devices that receives the radiation leaving the patient to create an image

The _________ of an x-ray beam affects its interaction with anatomic tissue

Increased _______ _______ ______ also increases x-ray beam attenuation

what happens when tissue density is increased attenuation - absorption - transmission -

provide information to the image receptor.

term used for when the attenuated x-ray beam leaves the patient's body also known as REMNNANT RADIATION and is COMPOSED OF both TRANSMITTED and SCATTERED RADIATION

what happens when tissue anatomic number is increased attenuation - absorption - transmission -

Increasing the x-ray energy will result in the decrease of _______ ________ , but increase Compton scattering percentage

Increased ______ _______ also increases beam attenuation
