lOMoARcPSD|22014731RSCI 210 Lab Final (Packets) No because the kvp isn't strong enough to penetrate the part - correct answers Would it be possible to create an image with
acceptable radiographic density of the mAs is multiplied 50 times?
Change in distance, use exposure maintenance formula to find new mAs to compensate new distance - correct answers What basic conclusion can be made related to SID on the radiographic density of the record image?
Misrepresentation of air-fluid levels - correct answers What happened to the view of the air fluid level when the film or the tube was angled?
Increased - correct answers As the OID is increased, the recorded size of the image is ...
Detail decreases - correct answers What effect, if any, does size distortion have on the resolution of the image?
Smallest amount of OID possible to combat magnification - correct answers What does the results of this experiment tell you about the role of OID in producing size distortion? How would you use this information to advantage to produce an image with minimal size distortion?
Decreased - correct answers As the SID is increased, the recorded size of the image is...
Detail increases - correct answers What effect, if any, does size distortion have on the resolution of the image?
Largest SID as reasonable - correct answers What does the results of this experiment tell you about the role of SID in producing size distortion? How would you use this information to produce an image with minimal size distortion
Decreased contrast - correct answers What happens to the contrast of the radiograph while increasing kvp?
If you want the same density, increase kvp but double mAs - correct answers Describe a situation where the 15% rule could be utilized to change the scale of contrast while maintaining density
20" has 4 times more density than 40" - correct answers Compare the radiographic density of the image produced at 20" SID to the image produced at the 40" SID
More density - correct answers Compare the radiographic density of the image produced at 40" SID to the image produced at the 60" SID
30" has 4 times more density than 60" - correct answers Compare the radiographic density of the image produced at 30" SID to the image produced at the 60" SID
No it's a function of the monitor - correct answers Is the brightness of the digital image changed with a change in time of exposure?
Direct relationship with seconds and density and an inverse relationship with seconds and exposure index - correct answers What relationship can be determined with a digital image between the time of exposure and exposure using the information you have gathered in this experiment?
If you do something to seconds or mA, you do the opposite to the other to keep the overall same density and mAs - correct
answers What relationship can be determined with a digital image between the time of exposure and mA setting— maintaining the mAs
