Features

Simply 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).

Flexible configurable

In line with your room design the laser system can be configured with a wall, post or bridge design and with a red, green or blue laser color.

Fits your workflow

Depending on your workflow you can choose between a movable sagittal, a movable sagittal and coronal or a movable sagittal, coronal and transversal plane to position and mark the patient.

Consistently precise

The positioning accuracy of ± 0.1 mm and the projection precision of ± 0.5 mm at a distance of 4 m is measured for every rail during production. The measurement data are delivered with the system. 

Reliable

The failsafe system verifies the positioning of the laser modules by two technically independent procedures before the lasers are switched on. 

Comfortably laser steering

You can control the mobile lasers either directly on the patient via a tablet PC or via a desktop PC in the control room. 

Configurations

DORADOnova 1 Laser System for Patient Marking

DORADOnova 1

For precise patient alignment and easy marking, you can move the sagittal laser plane. The transversal and coronal plane are projected via fixed laser lines.

DORADOnova 3 Laser System for Patient Marking

DORADOnova 3

The movable sagittal and coronal plane allow our laser system to offer increased flexibility for patient marking and virtual simulation. The transversal plane is projected via fixed lasers.

DORADOnova 5 Laser System for Patient Marking

DORADOnova 5

Our most versatile system offers the greatest degree of flexibility for marking and virtual simulation with five movable lasers (movable sagittal, coronal and transversal plane), No mechanical CT or LINAC couch movement is required which increases accuracy and eliminates the time-consuming and imprecise procedures.

State-of-the-art laser systems for optimal patient marking at CT/PET-CT

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 can LAP ensure projection precision?

The projection precision is influenced by the straightness of the rail and the temperature. During production, the projection accuracy of each rail is checked twice and documented in the Delivery Report. If it is not within the tolerance, the rail is not used. Only laser devices that pass these stringent checks will be used.

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.

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.
