Highest precision you can rely on

APOLLO room lasers are used for precise and repeatable positioning of radiotherapy patients. After imaging-based planning via CT or MRI, the patient is positioned at the linear accelerator. The finest laser lines project the LINAC isocenter coordinates onto the patient’s skin, allowing for precise alignment to millimeter accuracy with the CT/MRI. In addition, the room lasers are a fundamental component of quality assurance. They aid in the precise orientation of the phantom, to achieve measurement accuracy.

The APOLLO system has three (optionally four) lasers for the coronal, sagittal and transversal body planes. You can choose the laser color, line and/or cross laser, and mounting option, all adapted to your individual room situation. An optional fourth laser prevents possible shadowing from the LINAC gantry.

Thanks to their high quality, room lasers from LAP, remain in use and highly precise for an above-average number of years.

APOLLO - High precision you can rely on

Features of APOLLO room laser

Precise

Even at a distance of 4 meters, the maximum laser line width is 1 mm. The line straightness within the line shows barely any deviations, even at a distance of 3 meters. You can always be sure of the precision of our lasers.

Optimally visible

The different red, green, and blue diode colors, the optical room laser components are designed and manufactured with extreme accuracy. Plane parallel glass with anti-reflective coating prevents any interference with the laser beam. The brightness distribution remains constant at all times. Benefit from optimal visibility for precise patient positioning.

Stable

A high-quality aluminum housing reliably protects the fine mechanics and optical components inside. You don't need to fear damage even from gentle impacts. Highly shatterproof glass stands up to all the rigors of clinical daily life.

Flexible

Adapt the room laser mounting according to your individual room situation. Direct wall mounting or mounting on a freestanding support are both possible. In addition, the room laser can be inclined up to 45°. This gives you flexibility even in small rooms.

Easily adjustable

Laser adjustment is convenient via remote control. Fast and smooth laser position and focus adjustment save you time for QA and treatment.

Resistant to radiation

In environments surrounding linear accelerators, scattered radiation occurs. The components in our room lasers have been tested under extreme exposure conditions and optimized for these conditions. The many years of availability without compromising on quality is an exceptional track record that speaks for itself.
