New ‘Flight Simulator’ Technology Gives Neurosurgeons A Peek Inside Brain Before Surgery

NYU Langone Medical Center is now using a novel technology that serves as a “flight simulator” for neurosurgeons, allowing them to rehearse complicated brain surgeries before making an actual incision on a patient.

The new simulator, called the Surgical Rehearsal Platform (SRP), creates an individualized walkthrough for neurosurgeons based on 3D imaging taken from the patient’s CT and MRI scans. Surgeons then plan and rehearse the surgeries using the unique software, which combines life-like tissue reaction with accurate modeling of surgical tools and clamps, to enable them to navigate multiple-angled models of a patient’s brain and vasculature.

The SRP was developed by Surgical Theater of Cleveland, Ohio. This augmented reality technology may help improve safety and efficiency during surgeries for conditions including pituitary tumors, skull base tumors, intrinsic brain tumors, aneurysms, and arteriovenous malformations (AVMs), and could potentially allow surgeons from around the world to simultaneously collaborate on a patient’s case in real-time.

 ”We are excited to partner with Surgical Theater to bring their Surgery Rehearsal Platform to our institution,” said John G. Golfinos, MD, chair of the Department of Neurosurgery at NYU Langone Medical Center and associate professor of neurosurgery at NYU School of Medicine. “The reaction of tissue in these 3D images is incredibly life-like and modeling of surgical tools is equally impressive. The SRP also will enhance the training of medical students, residents and fellows and help them hone their skills in new and more meaningful ways.”

When using the SRP, surgeons can rehearse a specific patient’s case on computer monitors connected to controllers that simulate surgical tools. For example, when rehearsing a surgery for an aneurysm, the SRP reacts realistically when the surgeon virtually applies a clip to the blood vessel. The surgeon then can assess the tissue’s mechanical properties and view realistic microscopic characteristics including shadowing and texture to plan approaches, so that when the real surgery is being performed, doctors have rehearsed and already have a mental picture of what is being seen in the OR.

The SRP obtained clearance from the U.S. Food and Drug Administration (FDA) in February 2013 as a pre-operative software for simulating and evaluating surgical treatment options.

In addition, a newer-generation of this technology from Surgical Theater, the Surgical Navigation Advanced Platform (SNAP), has an application pending with the FDA to allow the tool to be taken into the operating room, so surgeons can see behind arteries and other critical structures in real-time.

New app shuffles thoughts to summon sleep

If counting sheep can’t help you sleep, you could try thinking of an elephant, French toast and scuba diving.

Simon Fraser University researcher Luc Beaudoin has created mySleepButton, a first-of-its-kind app that harnesses the power of the imagination to help users nod off.

Distributed by Apple as a free iTunes download, the app incorporates concepts from cognitive science, a multidisciplinary study of the mind and its processes. It works by preventing sleep-interfering thoughts and activating a mechanism that could help trigger sleep.

Based on the “cognitive shuffle” technique developed by Beaudoin, an SFU adjunct education professor, the app works by prompting users to imagine various objects or scenes in rapid succession.

“For example, one moment, users may be directed to think of a baby, then next a football game, then beans, a ball, London and so on,” he says.

The method is based on the uniquely incoherent nature of sleep onset “mentation,” a term used by Beaudoin that refers to all kinds of mental activity.

“As you fall asleep, you tend to entertain various detached thoughts and images. The app gets users to think in a manner that, like sleep onset, is both visual and random,” explains Beaudoin. “In a nutshell, it’s a case of ‘fake it until you make it.’

“Brain areas involved in controlling sleep detect that sense-making has been suspended. This basically gives them an implicit license to continue the transition to sleep,” he says.

Executive functions—brain functions like planning, worrying and problem solving that are vital for helping us make sense of the world during waking hours—can delay sleep when they don’t switch off at bed time.

By prompting users to interpret and visualize words, mySleepButton can help deactivate these executive functions.

“While you’re thinking about random objects or scenes, you can’t think about your mortgage, an important meeting or an impending divorce,” says Beaudoin.

“That’s because, to a certain extent, we all have one track minds. It’s very hard to think about multiple distinct things at the same time.”

Beaudoin, an associate member of SFU’s cognitive science program, says the app could also help increase cognitive productivity.

“Quality of work decreases when people are sleep-deprived and getting adequate sleep is very important for cognitive performance,” he says.

The app has potential applications for industries that employ scientific knowledge workers, such as software and aviation, or for employees on variable schedules who need to be alert, such as transportation workers.

The application is also a valuable research tool for sleep science and cognitive science, says Beaudoin, who authored the book Cognitive Productivity.

Data collected from consenting users could be used in scientific studies or feed directly into further development of the app.

Listening to bipolar disorder: Smartphone app detects mood swings via voice analysis
A smartphone app that monitors subtle qualities of a person’s voice during everyday phone conversations shows promise for detecting early signs of mood changes in people with bipolar disorder, a University of Michigan team reports.
While the app still needs much testing before widespread use, early results from a small group of patients show its potential to monitor moods while protecting privacy.
The researchers hope the app will eventually give people with bipolar disorder and their health care teams an early warning of the changing moods that give the condition its name. The technology could also help people with other conditions.
"We only ask that an individual use his or her smart phone as he or she normally would," said Emily Mower Provost, assistant professor of computer science and engineering who co-led the project. "We collect speech data from the smart phone and process the data in a privacy preserving manner to learn the acoustic patterns associated with harmful mood variations."

Students ‘print’ pink prosthetic arm for teen girl
Thirteen-year-old Sydney Kendall had one request for the Washington University in St. Louis students building her a robotic prosthetic arm: Make it pink.
Kendall Gretsch, Henry Lather and Kranti Peddada, seniors studying biomedical engineering in the School of Engineering & Applied Science, accomplished that and more. Using a 3-D printer, they created a robotic prosthetic arm out of bright-pink plastic. Total cost: $200, a fraction of the price of standard prosthetics, which start at $6,000.
“Currently, prosthetics are very expensive, and because kids keep growing, it is too costly for them to have the latest technology,” said Sydney’s mother, Beth Kendall. “With the 3-D printer, a prosthetic can be made much less expensive. The possibilities of what can be done to improve prosthetics using this technology is very exciting.”
Sydney lost her right arm in a boating accident when she was six years old. She learned to write with her left hand, but found most tasks difficult to accomplish with her prosthetic arm. Sydney said her new arm is easy to manipulate. By moving her shoulder, she can direct the arm to throw a ball, move a computer mouse and perform other tasks.
Peddada said it was thrilling to observe Sydney use her arm.
“It really showed us the great things you can accomplish when you bridge medicine and technology,” Peddada said.
The students developed the robotic hand as part of their engineering design course with Joseph Klaesner, PhD, associate professor of physical therapy at the School of Medicine. Several local medical practitioners, including orthopedic hand surgeons Charles A. Goldfarb, MD, and Lindley Wall, MD, both associate professors of orthopaedic surgery at the School of Medicine, served as mentors.
“They brought their engineering expertise, and we shared our practical experience with prosthetics and the needs of children,” Goldfarb wrote in a recent blog post about the project. “It was a valuable experience as Kendall, Henry and Kranti had no prosthetic experience and were able to think about the issues in a very different way.”
As Goldfarb explained, the WUSTL student design offers two key design differences that set it apart from similar “Robohand” devices that have been invented recently — the motor and the working thumb.
This prosthetic is battery-powered and controlled with an accelerometer (like in the iPhone). The thumb moves with a slightly different trigger (compared with finger motion).
Prosthetic limbs are tricky for patients of any age, and especially for children, noted Goldfarb, because they’re still growing and need to move to larger-sized devices on a regular basis. Since prosthetics have no sensation, some kids are more comfortable making do with their existing natural limbs, he added.
While 3-D printers can cost about $2,500, they are capable of producing artificial limbs at a relatively low individual cost.
“These prosthetic hands are really exciting because they are inexpensive, can be remade when the child grows, and they do offer functional abilities,” he said.

Google Glass puts the focus on Parkinson’s
The next generation of wearable computing is being trialled for the first time to evaluate its potential to support people with Parkinson’s.
Experts at Newcastle University are investigating Google Glass as an assistive aid to help people with Parkinson’s retain their independence for longer.
Glass is a wearable computer being developed by Google. Likened to the kind of technology fictionalised in the Hollywood Blockbuster Minority Report, at first glance Glass appears to be no more than a pair of designer glasses. But the system works like a hands-free smartphone, displaying information on the lens of the Glass. The technology is voice-operated and linked to the internet.
Not currently available outside the US, the five pairs of Glass at Newcastle University were donated by Google to allow researchers to test how they could be used to support people with long-term conditions.
Initial studies by the team - who are based in the University’s Digital Interaction Group in Culture Lab, part of the School of Computing Science - have focussed on the acceptability of Glass. They have been working with a group of Parkinson’s volunteers aged between 46-70 years.
Now they are working on the next stage of the project, using the technology to provide discreet prompts linked to key behaviours typical of Parkinson’s, such as reminding the individual to speak up or to swallow to prevent drooling. Glass can also be used as a personal reminder for things such as medication and appointments.
The team will also be exploring how the motion sensors in Glass can be used to support people with ‘freezing’, a behaviour caused by motor blocking a common symptom of Parkinson’s.
Led by Dr John Vines, PhD student Roisin McNaney and Dr Ivan Poliakov, this is the first UK trial of Glass. Presenting their initial findings later this month at the ACM Human Factors in Computing Systems (CHI) 2014 conference in Toronto, Canada, the team will show how emerging technologies can potentially be used to support people with progressive diseases such as Parkinson’s and dementia.
