Dose Information
If you are unsure about the correct Image Quality Ref-
erence mAs value, follow this simple procedure:
• Enter the (eff.) mAs value used for that type of pro-
tocol without CARE Dose 4D.
• There is a simple way of ascertaining what eff. mAs
CARE Dose 4D will use along the scan range: When
the topogram is complete shrink the scan range to
it's minimum. As you move this small box over the
topogram you can see how the eff. mAs displayed in
the Routine and Scan tab card varies along the
patient's body.
To achieve a certain eff. mAs at a patient's particular
body region you can move the small scan range to
this position and then adjust the Quality reference
mAs so that the displayed eff. mAs value is as
desired. After resizing the scan range to the range
for the examination, carefully observe the displayed
mean eff. mAs. After the subsequent scan is com-
pleted inspect the image quality to ensure that the
chosen Quality reference mAs is the right value.
• With that setting perform the first scan and carefully
inspect the image quality. In that first step the dose
may not be lower than without CARE Dose 4D but
will be well adapted to the patient’s attenuation,
resulting in improved image quality.
• Starting from that setting, reduce the Image Quality
Reference mAs step by step to meet the necessary
image quality level.
• Store the scan protocol with the adapted image qual-
ity reference mAs.
