LRA 211 Radiographic Image Production and Exposure(solved ) The earliest atomic theory is generally associated with - answer ? particles of an atom - answer protons, neutrons, electrons Characteristics of the electromagnetic spectrum - answer ? Characteristics of a Sine Wive - answer ? Ionization - answer the process of adding or removing electrons from an atom or molecule, which gives the atom or molecule a net charge x-ray production requirements - answer 1) X- ray tube with vacuum inside 2) Source of electrons 3) Method to accelerate electrons to great speed 4) Method to decelerate/stop electrons x-ray tube parts and construction - answer ? Allowable x-ray tube leakage radiation - answer ? Electromagnetic Induction - answer the process of creating a current in a circuit by changing a magnetic field Beam quality is affected by - answer kVp and filtration Beam quantity is primarily determined by - answer mAs Primary radiation is: - answer also called the useful beam, beam of x-rays that comes from the target Secondary radiation - answer X-radiation created when the primary beam interacts with matter Cardinal Methods of Radiation Protection are - answer Time Distance Shielding Contrast vs Scale - answer ? Transmission - answer those xrays photons that pass through the body and reach the IR Contrast Resolution - answer The ability of the image receptor to distinguish between objects having similar subject contrast, different for each anatomical part
