Key Technologies in Surgical Navigation

Optical Tracking Systems

Optical tracking is mest widely used technology in commercial chirurg navigation platforms. It employs two or more infrared (IR) cameras aranged around thee operation field to contect reflutivy markes attached tu instruments andhe patient 's anatomy. Thee system triangulates thee marker positions in 3D space with sub- milieter sivacy. Modern systems from commeries such as; 1reg; 11; FLT: 0; NDI 3I (Northern Digital Inc.); divitac.

Elektromagnetyczne przyrządy i aparatura do pomiaru lub kontroli ciśnienia

Elektromagnetyk (EM) tracking wykorzystuje nadajniki that generates a low- frequency magnetic field and small sensor coils embedded in instruments. Because magnetic fields intrastrastrate most materials, EM tracking does note require line of sight, making it ideal for endoscopic and needle- based procedures where these anatomy obseres optical markes, implants.

Image Registration

Image registration is the process of aligningg preoperative imaginag data (CT, MRI, PET) with the intraoperative patient anatomy. Withound precise registration, vigation is useless. Two main registration methods exist:

Real- time processing g continuously updates the registration as te patient i s moved or as tissue deforms. For example, during liver surgery, the liver 's shape changes with respirition; deformable registration algorithms warp thee preoperative model to match te live ultrasong or stereo camera images, maintaing navigation creacy the respirative through out thee respirative cycle.

Augmented Reality Overlays

Augmented reality (AR) enhances the surgeon 's natural view by projecting digital information directly onto the operative field. This can be accessed through:

Real- time processing is essential for AR because thee overlay mudt be updated at te refresh rate of thee display (typically 60- 90 Hz) and mutt adjuss for head movements, instrument motion, andd patient breakhing. Studies have shown that AR- guided procedures reduce the need tone wook way from thee operatical field, improwing hand- eye coordimentation and reducing operative tive time time by up to 20% in certain spine operatieries.
