The HP HEAD SUPPORTS - LOW DENSITY are used in combination with the base plates, EFFICAST® PRE-CUTS, cushions and other hardware from the RAYCAST® HIGH PRECISION and the AIO SOLUTION® sets. Together with the parts of these sets they form a reproducible patient positioning and immobilisation device in the field of radiotherapy. The head supports offer, together with the blocks & wedges, the opportunity to position the patient’s head in a stable and reproducible way.
The head supports can be positioned on the base plates or blocks & wedges by means of positioning knobs on the bottom of the head support. Always verify that the devices are positioned correctly on other cushions and parts.
This product is MRI-safe.
Physical Properties
The following physical properties apply to these devices:
Material:
PE foam
Density:
Low
Interface:
Round
Dimensions:
L 230 - 257 mm W 108 - 120 mm H 82 - 92 mm
Weight:
0.05 – 0.07 kg
Mechanical Properties
The Low Density head supports are made of PE foam covered with a PU coating resulting in a good dimensional stability.
The cushions used on the treatment machines are often used more frequently than those on the simulators and during the imaging stages. We therefore recommend rotating the sets between the different machines on a regular base to avoid differences in wear and tear of the cushions.
The maximum deformation measured after 100 uninterrupted pressure cycles with a compression strength of 500N on a surface of 5 cm x 5 cm is 28.1%. This corresponds to the force of 100 times per day the load of 50 kg applied with the palm of the hand.
Dosimetric Properties
These head supports are made of low density foam that has the following dosimetric properties per cm of material through which the beam passes:
Attenuation (± 0.15%)
Skin build-up (± 0.1 mm)
6 MV
15 MV
mm H2O equivalence
0.15%
0.05%
0.39 mm/mm material
Note: Use these numbers as a guidance only. Perform the measurements again in your department to verify these results.
