Setting the isocenter
To ensure that you do not have to readjust the table height during an examination
with different angulations and to ensure optimum evaluation results, the patient's
organ (e.g. heart) or region of interest must be positioned in the isocenter of the
C-arm.
Isocenter distance
The data display shows the distance between the tabletop (without mattress)
and the object of interest in the isocenter.
In this way, you can position the patient without fluoroscopy.
Positioning the patient approximately (without fluoroscopy)
u Place the C-arm in frontal position, if it is not already positioned there.
u Roughly center the organ in the beam path.
u Estimate the distance of the organ to be examined from the tabletop (T.O.D.).
u Set the table height so that the required distance is shown on the data display.
Depending on matress thickness and patient thickness, isocentric movements
are restricted.
