Health Solutions and Risks




So far, we’ve shown and discussed the wonderful applications and advantages of AR in various industries.
However, today we would like to talk about some of the inherent risks of this technology, and how they can be mitigated.

One of the fields AR can be useful is the healthcare industry. Among other uses, AR can be a useful tool for doctors; the following video demonstrates usage of AR to help explore and learn about various body organs:

If we take the next step in AR technology, it might be used in actual procedures the medicine industry has implemented AR to show alternative views of a patient from various imaging sources. Images from X-Ray, ultrasound, endoscopies and other graphic information that can be helpful in real-time are shown while a doctor is in a surgical procedure. AR aids surgeons to be more accurate when doing their job. AR is more advanced in neurosurgery (brain, spinal cord and peripheral nerves), otolaryngology (ear, mouth and nose) and maxillofacial (face and jaws) operations.

A disadvantage of using AR in medicine is that life and health are at stake and the system can fail, since it has been proved that AR has limitations regarding “high resolution, color depth, luminance, contrast, field of view, and focus depth[1]”. If a doctor perceives wrongly the information, when working with the patient, mistakes can be made that could damage an organ and complicating an operation. AR can project images inaccurate to reality since humans have rigid organs such as bones which are more static and semi-rigid organs such as the liver, which are constantly changing in shape (due to the blood irrigation and the body respiration), a past endoscopy can show how the organ was, but in a medical procedure the current organ’s state could have changed creating perception confusion to the surgeon leading to surgical negative results[2]. Even if AR can be of an advantage for surgery procedures, if the doctors make any surgical mistake, both the doctor and hospital might incur in negligence liabilities. Legal claims could be very costly (apart from the health at stake) for hospitals.

The good news is that people are always willing to improve technology: institutions such as the Technische Universitat München have projects that are targeted to improve and adapt the use of AR in the operation rooms and help the doctors make a better utilization of this instrument as the end users[3]. Another way to mitigate the risk is that surgeons should always trust their senses and complement it with AR as a useful tool.
