Virtual Reality (VR)-powered head-mounted wearable devices are leading to new developments in cardiovascular treatment and improved outcomes for patients, researchers report.

The VR technology is helping in cardiac care, includes education and training, pre-procedural planning, visualisation during a procedure and rehabilitation in post-stroke patients.

“For years, VR technology promised the ability for physicians to move beyond 2-D screens in order to understand organ anatomy noninvasively,” said Jennifer NA Silva, Assistant Professor at the Washington University’s School of Medicine in St. Louis.

However, bulky equipment and low-quality virtual images hindered these developments.

“Led by the mobile device industry, recent hardware and software developments-such as head mounted displays and advances in display systems-have enabled new classes of 3-D platforms that are transforming clinical cardiology,” Silva added in a paper appearing in the journal JACC: Basic to Translational Science.

VR provides complete control over the wearer’s visual and auditory experience as they interact within a completely synthetic environment, while Augmented Reality (AR) allows the wearer to see their native environment while placing 2-D or 3-D images within it.

Merged reality and Mixed Reality (MR) allow for interaction with digital objects while preserving a sense of presence within the true physical environment.

“These technologies make up the full spectrum of extended reality, which is transforming the practice of cardiovascular medicine,” the researchers noted.

The technology allows patients and family members to better understand their cardiac conditions, helping them to make more informed decisions surrounding their medical care.

Medical students and trainees can better visualise cardiac abnormalities with VR, which allows trainees to simulate operating environments and multiple physicians to interact while viewing the same educational material in a natural environment.

However, the authors said there were still challenges and limitations.

“These technologies are still constrained due to cost, size, weight and power to achieve the highest visual quality, mobility, processing speed and interactivity,” Silva said. (IANS)

The Circus Maximus Experience, opened in Rome this week and offers visitors the chance to relive the ancient splendors of chariot racing in the Imperial period of Rome through augmented and virtual reality. The innovative project implements interactive display technologies never before used in such a large outdoor area.

“Now you find yourself in front of the Arch of Titus, which was possibly built in the place of a more ancient arch and dedicated in the year 81 After Christ by the Roman Senate and people to Emperor Flavius”.

This is just an example of what modern-day visitors will be listening to in their headsets, while at the same time through special visors see a virtual rendering of the majestic 20-meter Arch of Titus in Rome’s Circus Maximus.

Thanks to a ground-breaking project using interactive display technology never before used in such an extended outdoor area, visitors are able to re-live the life in one of Rome’s undisputed landmarks.

Visitors immerse themselves in history for with overlapping images from the past and those of the reality of today. They are able to visualize architectural and landscape reconstructions of what life was like during all of the historical stages of the Circus Maximus.

They can see the ancient Murcia Valley enriched with buildings and walk around in the Circus among the shops of the time. They can visualize the Circus during Imperial times, the Middle Ages and in a more modern age.

The full itinerary involves eight stops including: the valley and the origins of the Circus, the Circus from Julius Caesar to Trajan, the Circus during the Imperial age, the cavea or tiered seating arena, the Arch of Titus, the tabernae or shops, the Circus during the Middle Ages and modern age, and lastly “A Day at the Circus” for an experience of the exciting chariot race of the quadrigas with the screams of incitement of the public and the overturning of wagons.
