➡️ LESSON DESCRIPTION: This lesson’s objectives are to explain the purpose of radiography grids and to briefly identify the types of x-ray equipment that use grids. This lesson also explains the impact of scatter radiation and grids on image quality. This lesson also explains how grids work within an imaging procedure and defines grid ratio. This lesson also explains the relationship between grid ratio and grid efficiency. Lesson objectives: *Explain the purpose of radiographic grids *Briefly identify the types of x-ray equipment that use grids *Explain the impact of scatter radiation on image quality *Explain the impact of grids on image quality *Explain how grids work within an imaging procedure *Define grid ratio *Explain the relationship between grid ratio and grid efficiency

my employer paid for a program yet here i am watching free youtube vids for additional clarity ggs, keep it up brother!
Very informative and helpful video. Thank you.
Sir please upload more videos it helps me a Lot big thanks to you sir please upload grid patterns video(off focus grid,cross grid,..etc) ❤❤❤❤❤

Awesome..keep it up....❤stay blessed......
Thanks slot sir.
I surveyed 120 qualified radiographers at a national conference in Australia about understanding how to use a focused grid. Only 1 in 4 knew how to use geometry to get the best results. If you failed to understand the geometry of a projection, you would also fail to understand how to apply that geometry to a focused grid. Here is the test I set kzread.info/dash/bejne/ZotlyZKOhrKtoZM.htmlsi=2kxhsXDyyb29gnTC It is interesting that only 5% of radiologists fail the test. Of the general public 90% fail and the ones who pass tend to be engineers, architects and builders, so there is a kind of illusion or presupposition there.
>scatter radiation adds useless information to the radiograph 😂😂
