Fixed and Movable Laser Modules for CT and PET-CT
Radiation Therapy
- 0.1 mm Positioning Accuracy
- 1 mm Line Width
- Two Configurations
- 700 mm Travel Range
The user chooses the optimal combination of lasers for patient marking. CT and PET-CT Dorado laser systems are precision tools for patient marking to the correct positioning during irradiation. The number of movable lasers can be configured according to individual workflow. The laser control software CARINAnav is delivered pre-installed on a tablet or desktop PC. Fine adjustment of the laser lines can be done manually by means of adjusting screws in all degrees of freedom.
Double Secure - Before the lasers will be switched on, the positioning of the laser modules are double-checked by use of two technically independent procedures.
Durable - Red laser diodes have been established on the market for more than 30 years, and have an operating life of over 30,000 hours.
Customizable - Depending on workflow, the user can choose whether the coronal laser line can also be traversed in addition to the sagittal.
Comfortably Moveable - The user can control the movable lasers via the tablet PC, or via the desktop PC in the control room.
Easy-to-calibrate - The movable and fixed lasers in the DORADO system can be manually fine-tuned with the supplied Wilke phantom.
Consistently precise - For consistent laser line precision over the entire 700 mm travel range, the mechanical components are manufactured to be virtually tolerance free and coordinate perfectly with one another.
Dorado 1 Laser Module
For precise patient alignment and easy marking, the sagittal laser line is user-adjustable. The transversal and coronal body planes are projected via fixed lasers.
Dorado 3 Laser Module
The two movable sagittal and coronal lines allow Dorado 3 system to offer increased flexibility for marking and virtual simulation. The transversal body plane is projected via fixed lasers.

CARINAnav – Smart Laser Control
The CARINAnav control system required for moving the laser consists of the laser control software and hardware aligned with it, such as a tablet or desktop PC. Various interfaces like LAP file format and DICOM are available for communication with the scanner. In some cases, a directly integrated laser control is available, in the scanner manufacturer software, such as in Siemens Syngo via RT Image Suite F.
