Dose adaptation guidance
On a system with a 3D depth camera, the patient size is calculated after
measuring the source-image-distance. The optimal dose adaptation setting for
the patient is indicated by a blinking orange frame. To apply this setting, press
the indicated patient size icon.
Figure 53: Patient size "extra small" is indicated as recommended dose
adaptation setting
The indicated setting is a recommendation. The user has to confirm that the
setting is correct. If the setting is not confirmed by the user, the medium
patient size is applied.
If none of the icons is indicated by a blinking orange frame, dose adaptation
guidance is not available and the user must assess the patient size and apply
the correct setting.
CAUTION:
Dose adaptation guidance overestimates the patient size if the
patient is not positioned flat against the surface of the mattress
or tabletop. Dose adaptiation guidance may be inaccurate if the
patient is moving.
CAUTION:
Dose adaptation guidance is not accurate if based on a wrong
bodypart. Make sure the correct thumbnail for the exposure is
selected.
Prerequisites for measuring the patient size:
• If the X-ray tube is not perpendicular to the DR detector reference plane,
the angle must not exceed 20 degrees.
• If the body part is too thick, the dose adaptation guidance may fail,
indicated by warning signs next to the patient size icons
Increase the SID.
• The table or mattress or the patient's body is not covered by a material that
is highly reflective, highly absorbent (black) or transparant
