Calculate the dose area product
The dose area product, DAP , is calculated with Equation (1):
Equation (1): DAP = Y x S x x S y x Q x k
2 /mAs) - conversion factor
❏ Y (µGy x m
❏ S x - scale index value for collimator adjustment (x-axis)
❏ S y - scale index value for collimator adjustment (y-axis)
❏ Q (mAs) - quantity of charge during exposure
2 2
❏ k (cm /m ) - constant. k= 6.40 (cm
◆ Read the value of Y (µGy x m
tube voltage (kV) used during exposure.
◆ Calculate the dose area product, DAP , with Equation (1).
