Brain Surgery Simulator Is Like Playing A Game, First

One sure way to avoid mistakes is to have a simulation before doctors perform surgeries. Brain Surgeons in Halifax, Canada can now do dry runs of their patients' brains using models of them. The simulator uses MRI images that allow them to get digital copies of their brains.
First, patient data from functional magnetic resonance imaging (fMRI) is rendered into a 3-D, high-resolution model of an individual's brain. After the model is loaded into the system, doctors can touch and manipulate tumors and other virtual objects on screens in real time using a physical instrument resembling a scalpel. The instrument has six degrees of freedom and re-creates the force-feedback of the real tool and the varying resistance of tissue in brain regions with differing toughness. Meanwhile, photo-realistic on-screen imagery shows the simulated surgery, including bleeding and pulsing gray matter.
Will it also have error detection and a time based counter that tells you how long more you have to perform the surgery? [Technology Review via PopSci]
As companies in the technology sector know how important security is for their users. That's why they update their systems with better functions so that nobody can easily access their data. In sight are the fingerprint sensors or the face recognition cameras. But there is nothing wrong with using traditional user and password methods. Read more
Whether you’re just getting started with digital marketing or you’ve been at it for a while, it’s easy to become engrossed in the day-to-day tasks without taking the time to look at the overall picture.
