Figure 2. (a) Plot of the fluoroscopic dose–area product (DAPF) normalized to the time of fluoroscopy (TF) vs the patient weight (BW). (b) Plot of the dose–area product (DAPA) accumulating during cine acquisition, normalized to the total number of recorded frames (NA) vs BW. The data are from the Philips Integris system. For the DAPA plot all examinations with erroneous dose measurements were eliminated as far as possible. n, number of examinations; r, correlation coefficient; RD, relative deviation, also indicated by the dashed lines.
