DORADOnova MR3T supports your (MR-only) workflow

DORADOnova MR3T is an MR-conditional laser system with a combination of fixed and movable lasers. The lasers project lines on three body planes for marking the patient while MR simulation. Subsequently these marked points remain on the skin and serve as reference for irridation at the linear accelerator. Our CARINAnav laser control provides an easy and comfortable control of the lasers exactly where you need them.

Features

Double safe

Before the lasers will be switched on the positioning of the laser modules are double-checked by use of two technically independent procedures.

Optimally visible

In line with your room design or lighting conditions, we offer lasers in red, green, or blue. All laser sources are diodes with an operating life of over 30,000 hours.

Easy to calibrate

All laser modules can be adjusted in six degrees of freedom (inclination, tilt, rotation) via remote control. Focusing also uses the remote control.

Consistently precise

For consistent laser line precision over the entire 700 mm travel path, the mechanical components are manufactured to be virtually tolerance free, and coordinate perfectly with one another.

MR-conditional

Certified by an independent testing facility DORADOnova MR3T is the world’s only laser systems for patient alignment which fulfill MRI conditional requirements up to 3 Tesla.

Comfortably movable

You can control the mobile lasers either on-the-move via the tablet PC, or via the desktop PC in the control room.

CARINAnav – 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.
