🗑
|
||||
| Range at which COMPTON SCATTERING can occur | show 🗑
|
||||
| show | 30-150 keV - depends on Atomic #, contributes to patient dose
🗑

| show | the ability of the IR to distinguish between levels of grey
🗑
|
||||
| Digital: Quantum ______ • Film: Quantum ______ | show 🗑
|
||||
| Image Artifact | show 🗑
|
||||
| show | Film - more sensitive to repeats due to exposure
🗑
|
||||
| show | •VISIBILITY (of anatomic structures): contrast and brightness •SHARPNESS (accuracy of structural lines): spatial resolution and distortion
🗑
|

🗑
|
||||
| Grid Frequency of a Focused Grid | show 🗑
|
||||
| show | k = Contrast with grid / contrast without grid
🗑
|
||||
| show | the ratio of primary to transmitted scattered radiation. "ability to clean up" - more scatter removal = greater selectivity
🗑
|
||||
| show | Recommended SID range to use with a focused grid. commonly 36-42 or 66-74"
🗑
