APOLLO - Highly precise laser system you can rely on

Dr. Stéphane Muraro, Chief medical physicist, Centre de Cancérologie du Grand Montpellier, France

"The LAP lasers are robust, and the external coordinate system provides an independent layer of security for patient alignment and QA tasks."

Features

Precise

At a distance of 1 to 4 meters, the maximum laser line width is 1 mm. Each line has been measured along its entire length and has a line straightness of ± 0.1 mm. In this way, you can always rely on the precision of your lasers.

Comfortably adjustable

With the remote control all lasers can be easily selected and finely adjusted in all degrees of freedom (parallel shift, tilt, rotation and focus). 

Stable

A high-quality aluminum housing reliably protects the fine mechanics and optical components inside. The housing withstands even strong impacts and and reduces misalignment due to vibration.

Optimally visible

The different red and green diode colors and the optical components are designed and manufactured with highest 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.

Fits your room

With the optional accessories, the lasers can be optimally adapted to your individual treatment room. Whether you need to bridge a false ceiling, have the lasers free standing, or have the laser project from a different angle (by default, the ASTOR can be tilted up to 45°), you can install your lasers safely, practically, and aesthetically.

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.

Supported LINACs

C-Arm LINACs

C-Arm LINACs

The APOLLO laser system has three or four lasers for the projection of the isocentre. The fourth laser prevents shadowing from the LINAC gantry in its initial position.

Bore-type LINACs

Bore-type LINACs

The APOLLO laser system has three crosshair lasers to project a virtual isocentre with a defined off-set.

Patient needs to be positioned in the bore 

  • Odd back - Unhealthy Lifting
  • Arduoos to go for the '"last millimeter"
  • Very difficult to position bigger patients

Patient can be positioned outside the bore

  • Straight back- Healthy lifting
  • Easy to go for the "last millimeter"
  • Positioning bigger patients is no a problem

Q&A

How can I configure the APOLLO?

You can configure each APOLLO as you need to. Preconfigured sets of three or four lasers to project the coronal, sagittal and transversal plane are available. A fourth laser prevents shadowing from the LINAC gantry. You can configure the laser color of the system and for each laser in line or cross laser and mounting option, all adapted to your individual room situation. 

Which color should I choose?

Historically, red was the only laser color that could be technically realized for a long time. Today, the laser colors red, green and blue can also be offered. Here, the human eye perceives green as a sharper line than red and blue sharper than green.  Another aspect you should consider is the skin color of your patients. Overall, after 20 years of experience, it can be stated that the green laser color is the most popular.

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. 

Do I get a quality report?

Yes, during production a Delivery Report with all the quality parameters is created for each laser system, which is handed over to our customers after installation.

How can I combine the imaging modalities CT and MRI for radiation therapy?

The DORADOnova laser system can be used to project reference or target coordinates on the patient's skin, which are then marked by clinical staff. These coordinates serve as the basis for patient planning and are used to position the patient on the MRI: Using the DORADOnova MR3T Laser System, the same coordinates that were used on the CT are projected and the patient is aligned with them. 
This lays the foundation for reproducible positioning of your patients throughout the different imaging modalities.
