Chapter 10: Radiographic Exposure Technique Flashcards
WebThe radiation inverse square law specifies that: the intensity of the radiation goes down by the square of the distance from the source. For instance if you move twice as far … WebTo change the technique to 40 mAs: 400 mA x .1s+ 40 mAs. or. 200 mA x .2s= mAs. *Ma and exposure time are inverse when maintaing the same mAs. Can maintain the number of photons (same mAs) and shorten the exposure time (reduce motion) If one changes the mA station from 200 to 400 mA, twice as many electrons will flow for the cathode to the anode. ohio state parks cabins with hot tubs
The Inverse Square Law and the direct square law « …
WebIt takes at least 1 pixel to demonstrated one line pair. False Pixel size determine the smallest detail that can be demonstrated in a digital image. True As SID increases (select all that apply): Film Density = DECREASE Detail Sharpness = INCREASE Size Distortion = INCREASE Contrast = NO EFFECT As focal spot increases (select all that apply): Webdensity definition. overall blackness of the radiograph. mAs. - amount/quantity of radiation produced in a beam. - controlling factor of density. mA. - actual tube current. - the number of electrons that travel from cathode to anode during an exposure. - higher mA --> more electrons --> more photons --> greater the density. WebIn Coulomb's Law, the distance between charges appears in the equation as 1 / r 2 1/r^2 1 / r 2 1, slash, r, squared. That makes Coulomb's Law an example of an inverse square law. Another well-known inverse square law is Newton's Law of Gravitation. It makes intuitive sense that electric force goes down as the distance between two charged ... myhousing oregon
