Witryna10 kwi 2024 · However, some organ specific image quality differences are seen for anterior crus and posterior crus of the stapes. Using a constant ED, the average image quality degrades when using tube voltages that are higher than 100 kVp. The protocols 4 and 5 offered a lower mean image quality resulting from using 110 kVp and 120 kVp. Witryna12 maj 2012 · Add a comment. 7.
