GENERAL DESCRIPTION

3.2.3 RX EXPOSURE TIME

In the following tables the exposure times (s) associated to kV and mAs are reported. Since

the apparatus is a device functioning with a two point technique (kV and mAs) we remind that the

values indicated in the table are merely theoretical and can undergo a variation in relation to the

tolerance of the mA.
