What is the formula to calculate the coverage (x) of the X-rays in terms of source-patient distance (d) and bevel angle (θ)?
What is the formula to calculate the coverage (x) of the X-rays in terms of source-patient distance (d) and bevel angle (θ)?
- x = d * cos(θ)
- x = d * sin(θ)
- x = d / tan(θ)
- x = d * tan(θ) (correct)
