ASTOR - HIGH PRECISION TOOLS FOR PATIENT POSITIONING
Laser systems for patient alignment in RT
In radiotherapy precise, reproducible and fast positioning of patients are required for successful treatments and high patient throughput.
After the initial patient marking process at CT or MRI the patient will be repositioned on the LINAC using cross hair and sagittal line lasers. The fixed lasers are aligned to the isocenter of the LINAC and enable isocentric positioning of the patient.
Integrated in a superior aluminium housing our ASTOR room laser combines advanced optics, high precision mechanics and state of the art electronics to ensure the highest level of stability and reliability.
Offering various configurations the ASTOR lasers are perfectly suited to meet all room requirements.
Unique technology
PRECISE
LAP ULTRALINE is the result of advanced mechanical components and unique optoelectronics used to generate and align laser lines for medical applications. The ultrafine and very long lines meet the high quality requirements for linearity and brightness distribution.

LAP laser systems are fitted with unbreakable, specially flattened glass windows. This minimizes scattering and guarantees ultrafine lines at all transition angles.
Tilt bracket
LAP ASTOR lasers are equipped with adjustable tilting brackets allowing for rotation up to 45°. The ASTOR’s compact design makes it an ideal solution for tight mounting locations.
Easy tilt adjustment
The ASTOR laser’s horizontal and vertical tilt can be easily adjust without removing the cover. Translation, rotation, and focus are adjusted after removing the cover via the convenient quick lock mechanism.

MOUNTING VERSIONS
For patient alignment each LINAC room is equipped with at least three room lasers. One laser projects a sagittal line and two cross hair lasers project the transverse and horizontal lines. You are free to select from four mounting versions to perfectly match your existing room situation.

FREE STANDING COLUMN (POST)
For locations where wall mounts are not possible
the LAP ASTOR laser can be equipped with an
optional free standing column.
DID YOU KNOW?
To avoid shadowing effects from the LINAC gantry
a fourth ASTOR cross hair can be installed overhead.
