Alderson phantom

Two sets of C-arm CT scan parameters and effective dose are presented below for Artis zee systems (Siemens AG, Healthcare Sector, Forchheim, Germany). They include mean effective dose values for the head and Hver regions determined using a normal-size, male Alderson phantom with embedded TLDs. Since effective dose depends on phantom positioning and size, however, measurement outcomes may vary. This is why great care was taken to position the phantom identically for all experiments to obtain comparable results.
