Remnant radiation - Study guides, Class notes & Summaries

What is the lost of some energy from the x-ray beam as it passes through the tissue being imaged? - Beam attenuation The photoelectric affect involves the removal and or ejection of an electron. This process of removing an electron from an atom is? - Ionization When the x-ray photon strikes an atom within the tissue being imaged and looses "all" of it's energy to an "inner" shell electron of an atom the photon is set to have been ________ to undergo ________? - absorb; photoelectric i...

Non-Threshold - Any dose produces a response Thermionic Emission - Filament electrons are boiled off producing an electron cloud Bremsstrahlung - AKA Breaking Radiation. Occurs when a high speed electron from the cathode is deflected by the nucleus of a target atom Characteristic Radiation - Occurs when cathode electrons dislodge inner orbit electrons from the target atoms. Anode Heel Affect - Reduction of beam intensity due to interaction with heel of target Quality - Refers to penetrati...

Ionizing Radiation - radiation that is able to remove electrons from an atom through ionization Somatic effects - refers to the effects of radiation to the body being irradiated Genetic Effects - refers to effects of radiation to a germ cell's genetic code; effects the next generation Primary radiation - radiation exiting the x-ray tube Remnant radiation (or Exit Radiation) - x-rays the leave the patient and strike the image receptor attenuation - absorption and...

1895 - x rays were discovered in high-voltage electricity - xray beam energy is produced using x rays - pass through matter and strike an image receptor image receptor - converts the energy of x-rays into an image; cassetes/IP/film; converts information received x-ray production requirements - vacuum tube source of electrons high voltage target cathode - source of electrons (negative end of xray tube) voltage - method to accelerate electrons to great speed across the tube target - met...
