NOTE
The exposure values will automatically change according to the selected
patient size, image resolution and ULD setting. The preset exposure values
are shown in section "Adjusting exposure values for current exposure" on
11.8 Adjusting exposure values for current exposure
NOTE
Always try to minimize the radiation dose to the patient.
The exposure values have been preset at the factory for each patient size,
image resolution and ULD (Ultra Low Dose) setting. The preset exposure
values are average values and they are only meant to guide the user.
The preset exposure values are shown in the following tables.
