Cost-conscious positioning precision
Our ASTOR room lasers allow precisely reproducible positioning of the patient on the linear accelerator. The finest laser lines, with a max. 1 mm width, project the isocenter for highly precise patient positioning. Room lasers are also a fundamental element of phantom alignment for quality assurance.
The ASTOR system has three or four lasers for alignment with skin markings. You can choose laser color, design variant, and line or cross lasers, all individually adapted to your room situation and workflow. A fourth laser is used to prevent potential shadowing from the gantry in its initial position.
Ultra-precise laser lines in red or green are made possible by state-of-the-art precision mechanics and optics. ASTOR room lasers are reduced to the essential, so even a modest budget can achieve the highest degree of precision.

How can I configure the ASTOR?
You can configure each ASTOR 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 and green can also be offered. Here, the human eye perceives green as a sharper line than red. 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.
