Patient marking and positioning at CT/PET-CT

Our movable lasers in the CT and PET-CT project the radiation coordinates required for precise alignment of the patient at the LINAC.

Save valuable time at the linear accelerator and prepare your patients at the imaging stage for the fast and repeatable positioning. With their flexible configuration, laser systems from LAP provide support for all treatment planning workflows. For safe and successful installation, we plan your individual radiotherapy imaging room in consultation with you and your tomograph manufacturer.

CT/PET-CT imaging in radiation therapy

The success of radiation therapy is closely related to the ability to accurately define, plan, and deliver radiation treatment to the tumor, while limiting the dose to normal tissue.

Computed tomography scans (CT scans) in the treatment position form the basis for treatment planning with contouring the target tumor volumes, and defining the organs at risk. The CT scan is required for precise dose calculation with the treatment planning system.

The location of the treatment isocenter is defined based on target volume and treatment area. As soon as the treatment isocenter is determined, or “marked”, these coordinates become part of the treatment plan and are the reference for subsequent dose calculations.

External laser systems are essential to patient marking: projecting the coordinates and marking them on the patient’s skin is required for precise positioning in the linear accelerator.

Benefits

Safety trough precision

Fine, clearly visible laser lines and accurate traversing equipment are required for marking. LAP laser systems’ modern laser sources and unprecedented traversing accuracy offer the highest degree of precision.

Efficient workflows

Different regulations allow seamless adaptation to your individual workflows. Relative, absolute, or reference point marking can be implemented efficiently.

Flexible room planning

There are various possibilities for combining wall-, ceiling-, or floor-mounted units. Different attachment systems and flexible, adjustable retainers allow us to adapt the laser system to your room.

Safety trough stability

It is increasingly likely that the precisely adjusted laser will be jostled as a result of cleaning, collisions, or the hustle and bustle of everyday work. The robust aluminum housing reliably protects the mechanics and electronics from external impacts.

Reproducible precision

Long laser lines, which can also traverse along the entire length of the gantry, allow comprehensive marking. Precise optics and the precision mechanics of the traversing units allow a position to be reproduced at any time.

Proven reliability

The characteristic features of laser systems from LAP are sophisticated technology, quality and design for more than 30 years. Our moving laser systems for patient marking are recommended by all leading CT scanner vendors.
