[Experimental dosimetric comparison between single tomography and multiple simultaneous tomography with Synchroplan in clinical practice].

Reference is made to a dosimetric comparison between single tomography and simultaneous multiple tomography with Synchroplan in 10 patients subjected to nefroangiotomography. Data from several thermoluminescence dosimeters placed on different parts of the body were used in a careful statistical analysis that showed the absence of significant differences in absorbed dose in function of constitutional habitus. It was also found that the dose absorbed for 6 tomograms of the renal cavities in single tomography was about 4 times higher than with the Synchroplan (using a previously experimented set of high-sensitivity intensifying screens), which provides 6 tomograms in the same dynamic phase at different levels for the same exposure.
