VISUALIZATION SYSTEM FOR MINIMALLY INVASIVE SURGERY

Augmented-Reality System in the Operating Room [ARSOR].

ARSOR is a pioneering system that allows the visualization of volumetric information projected directly on the patient’s body while in the operating room.

Through a wireless remote, the surgeon can visualize the inside of the patient’s body without having to cut, which allows the visualization of the pathology, its identification, location, and marking.

This is made possible thanks to the advanced multimodal workstation for processing digital medical images KDS, adapted to correct optical distorsions and allowing error-free identification and anchoring.

BENEFITS OF THE SYSTEM

Easy and widespread minimally invasive surgery, which means:

•Less pain

•Faster recuperation

•Less medication and anaesthesia

•Lower risk

•Less time

•Lower costs

•Fast, easy and affordable system

TECHNICAL CHALLENGES OVERCOME:

The development of AROR has meant a considerable investment in order to overcome serious technical challenges, basically:

OPTICAL

•Geometrical distorsion: due to the non-planar surface

•Viewpoint-ignorant projection: projection cannot correctly be seen by user due to position of the projector

•Radiometric distortion: surface color modulation

•Uneven projection: non-uniform brightness when projection is oblique

ANCHORING POINTS

•Patient-Projection Anchoring Points challenges overcome by our algorithms:

•Anatomic abnormalities: patient dependent

•Reduced imaged area: anatomic section variable

•Pathology evolution: may affect pre-determined or standard selection

SPATIAL LOCALIZATION

•Anatomic-Pathology Spatial-Localization challenges overcome by our algorithms:

•Metabolic-caused deviation: biological activity

•Anatomic-caused deviation: mechanical activity

•Pathology evolution: may affect pre-determined or standard selection
