High precision room lasers for a magnetic environment
APOLLO MR3T lasers have barely ferromagnetic resonance. Hence they are convenient for a magnetic environment such as know with an MRI or MR LINAC room.
Not only for positioning of patients but also for precice placement of phantoms for quality assurance room lasers are an optimal solution. The exact positioning improves the safeness which is a crucial factor in radiation therapy. Thanks to their high quality, room lasers from LAP, remain in use and highly precise for an above-average number of years.
Supported MR-LINACs
The latest development in radiation therapy is the MR-LINAC, which combines imaging and treatment in one device. Lasers lay the foundation for reproducible positioning of the patient so that adaptive planning on the daily updated image data can be used without complex conversion and little to no rigid and deformable image registration algorithms.
In addition, the room lasers are a fundamental component of quality assurance for all those for whom indexing offers too little security. They aid in the precise orientation of the phantom, to achieve measurement accuracy.

Q&A
How long is the laser line?
The length of the laser line is equal to the distance between laser source and patient. Therefore, for example, the laser line is only one meter long at a distance of one meter, but 4 meters long at a distance of 4 meters.
How long is the lifetime of a laser system?
Since the lifetime of a laser system is essentially defined by the lifetime of the laser diode, the specifications of the laser diode manufacturer are taken into account. This results in a lifetime of approx. 10 years.
Is a room planning included?
Yes, a room planning and consultation is included, free of charge.
