Quizlet Proportional Increase Calculator
Quizlet proportional increase in SID and ODF applied radiographic calculations is a crucial aspect of medical imaging. It helps optimize image quality and reduce radiation dose to patients.
- Enter the Source to Image Receptor Distance (SID) in centimeters.
- Enter the Object to Detector Distance (ODF) in centimeters.
- Select the desired factor (1.5, 2, or 2.5).
- Click ‘Calculate’.
The calculation is based on the formula: New SID = Old SID * (1 + Factor) and New ODF = Old ODF / (1 + Factor).
| Old SID (cm) | Old ODF (cm) | Factor | New SID (cm) | New ODF (cm) |
|---|---|---|---|---|
| 100 | 50 | 1.5 | 150 | 33.33 |
| Factor | Average Increase in SID | Average Decrease in ODF |
|---|---|---|
| 1.5 | 50% | 33.33% |
- Always round the results to the nearest whole number.
- Consider the maximum SID and minimum ODF your equipment can handle.
What is the difference between SID and ODF?
SID is the distance from the X-ray tube to the image receptor, while ODF is the distance from the object being imaged to the image receptor.
