In the rapidly evolving world of medical technology, Augmented Reality (AR) surgery stands out as a significant innovation, aiming to transform traditional surgical practices. Steve Cvetko, Chief Innovation Officer at Novarad and a pioneering force behind VisAR Augmented Reality Surgical Navigation, discusses the potential of AR to tranform the healthcare industry by offering more precise and reliable surgical procedures.

Enhancing Anatomical Precision with AR

“The primary advantage of immersive augmented reality in surgical navigation lies in its ability to overlay critical information directly onto the surgeon’s field of view,” explains Steve Cvetko.

This innovative approach is particularly beneficial in surgeries involving diseased or inflamed organs, where AR can provide a real-time, exact representation of the patient’s anatomy, thereby ensuring better outcomes.

The Accuracy and Reliability of AR Surgery

Patient Registration and Calibration

One of the cornerstones of AR surgery’s success is the accuracy of patient registration and system calibration. Cvetko outlines several methods that contribute to this precision:

  • Modality Registration: Ensures the patient’s position is fixed within the medical imaging modality, critical for accurate image overlay.
  • Landmark Registration: Involves pinpointing anatomy on the physical patient, matching these to medical imaging data.
  • Fiducial Registration: Uses physical items attached to the patient, visible in both medical images and to the navigation system, allowing for dynamic updates and increased accuracy.

Additionally, calibration plays a vital role, including room calibration, eye calibration, and instrument calibration, each ensuring that AR systems provide accurate, real-time guidance to surgeons.

Challenges and the Future of AR in Surgery

Despite its promise, AR in surgery faces challenges, particularly related to the dynamic nature of human anatomy. “Organs can shift, deform, or change in size, posing a significant hurdle to maintaining accurate AR representations,” Cvetko notes. Addressing these challenges requires ongoing innovation and collaboration among technologists, healthcare professionals, and regulatory bodies.


Augmented Reality (AR) surgery is at the forefront of technological innovations in healthcare, offering a glimpse into a future where surgical procedures are more precise, reliable, and tailored to individual patient needs. As we continue to navigate the complexities of integrating AR into clinical settings, the contributions of experts like Steve Cvetko and the advancements made by companies like Novarad are invaluable.
