LUTi Technology

• Optical tracking: LUTi uses a pair of stereo cameras to track the movement of specially designed surgical tools. Such an optical tracking system can provide sub millimeter localization accuracy and can simultaneously track multiple objects in realtime.
• Preoperative images: LUTi is a handy "GPS system" for surgeons. It uses preoperative images as the patient road map, including CT, MRI, fMRI, PET, and SPECT. By overlaying realtime surgical tool position on top of preoperative images, LUTi helps physicians to better diagnose diseases and deliver therapies.
• Registration procedure: in the context of Image-Guided Surgery (IGS), registration is referred to the process of establishing the spatial correspondence between preoperative images and the rtacked tools, for virtual overlay. LUTi has implemented a very simple and convenient registration method: surgeons can point and touch fiducial markers in any sequence and the system will automatically establish the paring and perform registration. After registration, the overall system accuracy is inevitably raised, to typically 2 mm (RMS).
• Dynamic compensation: LUTi incorporated a dynamic reference to give physicians more flexibility in carrying out clinical procedures. The specialist can reposition the patient or the camera as necessary. This will not affect the virtual overlay and the accuracy of the navigation system.
• Custom tool design: currently, LUTi has a set of tracked tools specially designed for skull-based neurosurgery. We are actively expanding our tool collections to meet the requirements of different application areas. Leveraging our in-house design and manufacturing capabilities, LUTi can also help create your own tools according to your specifications.
