Laser Systems for Patient Positioning from ProPhotonix

Patient-positioning is an increasingly important and valuable consideration in medical and dental instruments, particularly for imaging and radiotherapy. Patient-positioning systems are evident in extra-oral dental scanning instruments, CT scanners, MRI systems, PET scanners as well as other medical instruments.

Ensuring that instruments are well aligned with the patient helps to ensure high quality imaging, giving clearer information and ultimately helping to achieve swift and accurate diagnoses. At ProPhotonix, we have over two decades of experience in the design and the manufacture of laser modules and have supplied systems for a variety of different patient positioning applications.

For Swift and Accurate Diagnoses

Patient-positioning systems typically use a laser module mounted alongside the imaging instruments, clearly showing where images will be taken and allowing the instruments and patient to align to get the best image. Usually a red (635nm) laser line or cross is used, to give a high level of visibility. In some cases a green laser module may be used because of the human eye’s sensitivity to green and the need for clarity when projected onto the skin of patients. Alignment of the laser beam with the body of the laser housing (bore-sighting) is critical to achieve a high level of accuracy for the positioning system.

Patient Alignment – Radiotherapy

Radiotherapy is deliberately destructive to tissue within the human body because it is intended to damage a malignant tumor. Precision and accuracy are particularly important in this application, as it could be damaging to the healthy tissue around that tumor if it is not precisely aligned.

Learn how ProPhotonix designed custom red and green OEM laser modules for a leading healthcare equipment provider to help precise targeting of a tumor’s location for treatment.

Experience & Expertise

Laser Technology Experts

As a laser diode distributor and a laser integrator with in-house engineering and manufacturing capabilities, ProPhotonix offers customers a unique combination of design expertise, strong supplier partnerships, and ongoing engineer-to-engineer support. Our broad range of products and expertise in laser design helps us to tailor our modules to the requirements of your system.

Robustness and reliability are two key considerations when deciding on a laser for patient alignment. If the lasers do not perform, a high-cost piece of equipment is not being fully utilized and patients aren’t being treated. All of our laser modules undergo significant product testing including ESD, vibrational, shock and thermal testing. In addition, we can fine tune our lasers optically to provide a superior depth of focus allowing for differing working distances. We can offer rugged, reliable laser modules with highly visible laser beams and bore-sighting on modules to <0.25°.
