AR in Invasive Surgeries
By MedTech Outlook | Wednesday, March 06, 2019
Augmented reality is a technology that has emerged as an innovative power in several industries. The applications of AR are improving the physical world. In healthcare, AR can enhance the quality of treatment for patients. AR is changing the way doctors learn, by projecting virtual information and structures over physical objects. Incorporating data visualization into diagnostic and treatment procedures helps to improve work efficiency, safety, cost, and enhance surgical training. Mounting an augmented reality device to a surgeon will save thousands of lives. Invasive surgeries now require AR glasses. It allows surgeons to stay focused on the operation supported by the vital information they need.
At Pisa’s University, Italy, researchers of the Vostars (Video and Optical See- Through Augmented Reality Surgical Systems) project are developing a new kind of surgical visor in a bid to improve the accuracy of interventions and reduce surgery times by at least 11 percent. A doctor can see the anatomy of the patient in reality through this device where the virtual information is acquired from the radiological images of the patient. During repositioning the parts of the facial skeleton, the visor will be capable of joining 3D images with the accurate physiological details of the patient. This head-mounted display system also presents a patient’s vital signs including heart rate, body temperature, blood pressure, and breathing rates, directly into the surgeon’s field of vision. The system works by capturing what the surgeon sees from a head-mounted camera. The system then augments this image of reality with the patient’s medical images, collected from CT, MRI, or 3DUS scans.
AR systems are becoming comparable to traditional techniques, with precision and safety for clinical practice. Augmented reality is a powerful tool possibly capable of revolutionizing the old way of surgery through a new intelligent method. In the future, AR is expected to serve as an advanced human-computer interface, working with surgeons, allowing them to achieve even better results. However, several problems need to be examined before augmented reality is implemented into the routine practices.
