Causes of grid cutoff, when using focused reciprocating grids, include which of the following? 1. inadequate SID 2. x-ray tube off-center with the long axis of the lead strips 3. angling the beam in the direction of the lead stripes

As a radiographer, you are using a DR system that displays EI#’s as part of the DICOM header. The EI#s are calculated as directly proportional and linear to exposure. The image you have created shows marginal quantum noise and an EI# of 1400. The exposure technique you used was 85 kVp@ 15 mAs. To improve image quality and eliminate the objectionable noise, your next step should be to
