A patient comes in for a knee X-ray. The technique used was 68 kVp, 6 mAs, 45” SID and it created an EI of 511 (which ended up being about a +0.06 DI) and a DAP of 682 mGycm(2). If we wanted to change the distance to 60” to reduce magnification, how much would the dose change if we didn’t change the technique?
