Workflow Step

For departments practicing MRgRT, MICRO+™ MR offers remote control laser positioning in an MR environment. It’s MR-compatible, up to 3 Tesla.

Accuracy at the Patient
With laser line widths of ≤0.5 mm for all colors, and industry-leading lengths of ≥4 meters at 3 meters, MICRO+ MR offers precision and flexibility for your workflow.

Remote Controlled, Workflow Optimized
Lose the ladder, with easy adjustments via an included remote control. Backlit for visibility in darkly lit rooms, the remote easily synchronizes and controls multiple lasers with Bluetooth technology (no line of sight needed). A locator feature helps in case of misplacement.

The system mounts to walls or ceiling, keeping MR rooms organized, and includes an MRI-compliant power supply kit.

Support your MRgRT workflow with easy, remote-controlled lasers.

Tool-Free Access

Reinforced housing with tool-free entry offers reliability and efficient service and alignment adjustments.

Configuration Flexibility

3-laser system (3 crosshairs) or 4-laser system (3 crosshairs and 1 sagittal) configurations available
