Patient Positioning
Präzise Platzierung dank optoelektronischer Technologien
Why is the correct position important for doctors and patients?
In order to be able to make a meaningful diagnosis with C-arm X-ray, MRI, and CT equipment, patients must be positioned precisely in the device. Laser markings help to align them quickly and accurately. This means that meaningful images can be produced from the very first scan and the patient does not have to be exposed to further potentially harmful doses of radiation.
“Please treat here!”
Positioning aids are not only used in imaging procedures, but also in various forms of therapy, such as radiation therapy. Even in the operating room, laser markings show the doctor where to place the scalpel. Pilot lasers, which use a visible laser beam to indicate where the invisible therapeutic or surgical laser is currently located, are helpful here. In tumor therapy, for example, this enables precise and targeted laser surgical treatment.
Compact, bright and eye-safe
Positioning lasers for medical technology have to meet several requirements at the same time. Small laser modules are advantageous, as space in medical devices is often limited. The projected lines or patterns must be sharp and precise to ensure exact positioning. At the same time, the lasers must also meet high safety standards so as not to endanger patients or medical staff. In medical devices, most positioning lasers therefore comply with laser class 1, which means that they are also safe for patients in whom the eyelid closure reflex no longer works because, for example, they are under the influence of medication or anesthesia.

Dot, Line, Cross-hairs Lasers: When Do I Need What?
Laser für die Patientenpositionierung unterscheiden sich in erster Linie in Strahlform und -farbe. Je nach Anwendung werden Punkt-, Linien- oder Kreuzlaser verwendet. Die Wahl der Farbe hängt dabei von den Umgebungsbedingungen und den Anforderungen an Sichtbarkeit und Präzision ab. Während grüne Laser heller erscheinen und auf Haut und Textilien stärkeren Kontrast bieten, findet man die kostengünstigeren roten Laser häufig in routinemäßigen Anwendungen, bei denen keine besondere Anpassung an Umgebungsbedingungen erforderlich ist.
Jede Strahlform wird in der Medizintechnik für spezielle Aufgaben eingesetzt:
- Linienlaser sind die häufigste Strahlform in der Patientenpositionierung. Sie zeigen zum Beispiel in der Strahlentherapie oder bei CT/MRT an, wo der Körper ausgerichtet werden muss.
- Punktlaser bieten in einem kleinen Bereich höchste Präzision und eignen sich daher optimal als Referenzmarkierung oder zur genauen Ausrichtung eines bestimmten Punktes auf dem Körper um beispielsweise einen Nadeleinstich genau markieren zu können. Über größere Flächen bieten sie dagegen nur wenig Orientierungshilfe.
-
Kreuzlaser bieten Orientierung an zwei Achsen. In der Bildgebung – zum Beispiel bei C-Bogen-Röntgengeräten – markieren sie eine exakte Schnittebene oder den Fokuspunkt.
Areas of Application
Gentle on Patients in Every Medical Application
With the versatile FLEXPOINT® laser modules, LASER COMPONENTS offers a wide range of high-precision positioning aids for medical imaging and radiation therapy. They are available as dot, line, and cross-hair lasers and can be individually adapted to the requirements of our customers.
All modules are protected against electromagnetic interference and do not cause any unwanted emissions themselves. Whether used in radiology, MRI, CT, radiation therapy, or surgical procedures, our laser modules ensure fast and precise patient positioning in every single application.
In day-to-day clinical operations, this means more efficient and, above all, more precise diagnosis and treatment. For demanding applications in bright operating room environments or MRI-compatible systems, we develop custom solutions; for example, the housings can be adapted to your requirements and the lasers can be adjusted so that they fall into the required laser class. We are always ready to work with our customers to implement innovative new concepts for patient positioning.
Typical areas of application for positioning lasers in medicine include:
- C-arm X-ray machines
- MRT
- CT
- Radiation therapy
- Surgery
