The bottom plate contains three pair of bolts for locking the device holder. The device holder
positions are adjusted to the standard measurement positions in the three sections. A white cover is
provided to tap the phantom during off-periods to prevent water evaporation and changes in the liquid
parameters. On the phantom top, three reference markers are provided to identify the phantom
position with respect to the robot.
6.7. Device Holder
<Device Holder for SAM Twin Phantom>
The SAR in the phantom is approximately inversely proportional to the square of the distance
between the source and the liquid surface. For a source at 5 mm distance, a positioning
uncertainty of ± 0.5 mm would produce a SAR uncertainty of ± 20 %. Accurate device positioning
is therefore crucial for accurate and repeatable measurements. The positions in which the
devices must be measured are defined by the standards.
The DASY device holder is designed to cope with different positions given in the standard. It has
two scales for the device rotation (with respect to the body axis) and the device inclination (with
respect to the line between the ear reference points). The rotation center for both scales is the ear
reference point (EPR). Thus the device needs no repositioning when changing the angles.
The DASY device holder is constructed of low-loss POM material having the following dielectric
parameters: relative permittivity
ε = 3 and loss tangent δ = 0.02. The amount of dielectric material
has been reduced in the closest vicinity of the device, since measurements have suggested that
the influence of the clamp on the test results could thus be lowered.
<Laptop Extension Kit>
The extension is lightweight and made of POM, acrylic glass and foam. It fits easily on the upper
part of the mounting device in place of the phone positioned. The extension is fully compatible with
the SAM Twin and ELI phantoms.
