DORADOnova MR3T supports your (MR-only) workflow
Save precious time at the linear accelerator (LINAC) and prepare your patients in the best possible way at MRI. Lasers at MRI help project coordinates onto the patient's surface that are defined as a reference between the patient's internal and external anatomy. In this way the DORADOnova MR3T laser system enables precise registration of CT and MRI data and links imaging with planning and treatment as required by the report of AAPM Task Group 284. Furthermore it enables the MR-only workflow, as all patient marking workflows can be applied at the MRI.
DORADOnova MR3T is an MR-conditional laser system up to 3 Tesla with a combination of fixed and movable lasers. Choose between the laser colors red, green or blue. The lasers can be adjusted by remote control. The control software CARINAnav MR is supplied pre-installed.
Lay the foundation for reproducible positioning of your patients throughout the entire treatment with DORADOnova MR3T.
CARINAnav MR – smart laser control
The CARINAnav control system required for moving the laser consists of the laser control software and hardware aligned with it. Various interfaces like LAP file format and DICOM are available for communication with the scanner. In some cases, we also offer a directly integrated laser control in the scanner manufacturer software. You can find more information about CARINAnav here.

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.
