11.7 Selecting image resolution, Ultra Low Dose (ULD) and ProFace

Steps

1. Select field (1) to open a pop-up window.
2. Select the image resolution you wish to use (2). The voxel size options

are 600 / 450, 300, 200, 150 and 75 micrometres, depending on the

selected program.

3. Select the ULD (Ultra Low Dose) button (3) if you want to take an

exposure with a very low dose. The voxel size buttons turn green and

show a small apple.

4. Select the ProFace (optional feature) button (4) to add the 3D photo to

the exposure.

5. Select the green check mark button (5).

NOTE

The available options depend on the selected program.

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 page 60.

11.8 Adjusting exposure values for current exposure

About this task

NOTE

Always try to minimise 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.
