Penn Medicine, Intel to deploy innovative AI approach to identify brain tumors

Penn Medicine, Intel | May 13, 2020

  • Perelman School of Medicine is working with Intel to advance a new distributed machine learning technique.

  • The technique allows for researchers at disparate organizations around the world to work together to develop new deep learning initiatives without having to share data.

  • The research will be trained on the largest brain tumor dataset to date, without identifiable patient data leaving the individual collaborators.


Perelman School of Medicine at the University of Pennsylvania is working with Intel to advance a new distributed machine learning technique – one that allows for researchers at disparate organizations around the world to work together to develop new deep learning initiatives without having to share data.
 

WHY IT MATTERS

That approach, which aims for big advances in collaborative AI research while still maintaining patient privacy, is called federated learning.

Researchers at Penn Medicine have published findings that a federated-learning approach to medical-imaging AI could train a model to more than 99% of the accuracy of a model trained in the traditional, non-private method.

So Penn is working with 29 research institutions from the U.S. – as well as in Canada, the U.K., Germany, the Netherlands, Switzerland and India – using Intel technology to deploy a federated-learning approach to develop new deep learning models for identifying brain tumors.

n order to train and build a model to detect a brain tumor that could aid in early detection and better outcomes, these researchers need access to large amounts of relevant medical data. By using federated learning, they will be able to work together on building and training an algorithm to detect a brain tumor while protecting sensitive medical data.

Penn Medicine and Intel say the research will be trained on the largest brain tumor dataset to date, without identifiable patient data leaving the individual collaborators.
 

THE LARGER TREND

Even if more evidence is needed, AI and machine learning are proving their worth in the field of medical imaging. In April, for instance, a study on AI-augmented diabetic retinopathy screening indicated that such programs are cheaper than human grading – that a deep learning system would save on the roughly two minutes of human labor required to grade each case.

The Penn Medicine and Intel initiative is funded by a three-year, $1.2 million grant from the Informatics Technology for Cancer Research program of the National Institutes of Health.

Some of the collaborating institutions planning to participate in the first phase of this federation are the Hospital of the University of Pennsylvania, Washington University in St. Louis, the University of Pittsburgh Medical Center, Vanderbilt University, Queen's University, Technical University of Munich, University of Bern, King's College London and Tata Memorial Hospital.
 

ON THE RECORD


It is widely accepted by our scientific community that machine learning training requires ample and diverse data that no single institution can hold, this year, the federation will begin developing algorithms that identify brain tumors from a greatly expanded version of the International Brain Tumor Segmentation challenge dataset. This federation will allow medical researchers access to vastly greater amounts of healthcare data while protecting the security of that data.

- Dr. Spyridon Bakas at Penn's Center for Biomedical Image Computing and Analytics.


AI shows great promise for the early detection of brain tumors, but it will require more data than any single medical center holds to reach its full potential, Using Intel software and hardware and support from some of Intel Labs’ brightest minds, we are working with the University of Pennsylvania and a federation of 29 collaborating medical centers to advance the identification of brain tumors while protecting sensitive patient data.

- Jason Martin, principal engineer at Intel Labs.

19Labs and MOH Launch Historic Telemedicine Project to Transform Healthcare in Guyana

19Labs | December 20, 2022

In cooperation with the Ministry of Health and the Georgetown Public Hospital Corporation a telemedicine pilot program with GALE eClinics was launched in four remote areas of Guyana. "We have reached a milestone and begin a journey that has the potential to transform health." Dr. Leslie Ramsammy, GPHC Board Chairman During the Telemedicine Launch, 19Labs CEO, Ram Fish, joined Guyana's Health Minister, Dr. Frank Anthony, in Masakenari, or as it is better known locally, Gunns Village. They were welcomed by the village Toshao, Paul Chekema, and the village residents. Using the newly installed eClinic system, Gunns was able to connect to the Georgetown Public Hospital and the three other villages that form part of this pilot program. The program's purpose is to provide equitable healthcare to all of Guyana's citizens. This keeps in line with the vision of Guyana's President, Dr. Ali, of creating a 'world-class' healthcare system for Guyana. Dr. Ramsammy, began the launch by saying: "Our ambition is to improve health care for all of our people, and as we understand that we can't put…a Georgetown public-level hospital in every village, we believe that citizens, in every part of the country, could get access to basic healthcare…We have reached a stage this morning, where we could launch Guyana's national telemedicine program." One of the major challenges in achieving such a vision is the remote locations with the lack of connectivity. Gunns Village is a 5-day boat and land trek during the rainy season when planes cannot use the local airstrip. 19Labs is proud to provide a solution as the four health posts that are part of this pilot are now connected to the world through the internet over satellite. With the GALE eClinic Telemedicine units, even the most isolated village now has access to top-quality medical care. In a very short time, Gunns went from an area that had no connectivity, electricity, and little medical equipment, to the ability to instantly connect to the healthcare and staff of the Georgetown Public Hospital. Dr. Anthony said: "With the technology we have now installed, this particular health center has a full complement of internet-enabled devices which we will…be able to do ultrasounds, ECGs, and a whole host of other things to help to assess the patient." GALE eClinics replicate the full clinical experience providing and filling the need for both general health and specialty care including prenatal, OBGYN, maternal, cardiac, and chronic condition management. Our partnership goes beyond a one-time fix. The local communities now have access to more opportunities. Ram Fish said: "This goes even beyond just health care, [this transforms communities]. The equity that it brings to us also opens the eyes of people and places to different cultures, and different ways of doing things…It's about empowering with technology local young women and men who really become the centers of the communities beyond just health…This is the beginning of a journey…We will expand and work together to really make healthcare equitable across Guyana and beyond." About 19Labs 19Labs is the creator of GALE, Next Generation Point-of-Care platform for pharmacies, schools, and rural communities. GALE brings together cutting-edge diagnostic technologies from industry leaders like Zoom, Elo, Amwell, Eko, Samsung Mobile, MIR, Omron, Viasat, and many others in one smart, efficient, and cost-effective platform. It was designed from the ground up to be operated by non-healthcare professionals, in locations with limited infrastructure and optimized for low bandwidth and intermittent connectivity.

Healthcare Under Cyberattack: Unprotected Medical IoT Devices Threaten Patient Care

Capterra | November 30, 2022

The rising adoption of connected medical devices is accelerating cyberattacks, according to Capterra’s new Medical IoT Survey of healthcare IT professionals. The survey also reveals that 67% of healthcare cyberattacks impact patient data and nearly half impact patient care, an indication that rising security risks in the industry are leading to severe consequences in patient outcomes and privacy. The medical internet of things is helping to make healthcare more convenient, efficient, and patient-centric. However, connected devices with IoT sensors often have unprotected security vulnerabilities that endanger healthcare facilities, and even patients. In fact, medical practices with more than 70% of their devices connected are 24% more likely to experience a cyberattack than practices with 50% or fewer connected devices. “As a healthcare organization connects more medical devices to its network, its attack surface expands. Connected medical devices often go unmonitored for security vulnerabilities, and because they run on a wide array of software and hardware platforms, it’s difficult to monitor with a single tool. This means that many connected medical devices are left wide open to cyberattacks.” Zach Capers, senior security analyst at Capterra More than half of healthcare IT staff rate the cybersecurity threat level in the industry as high or extreme, yet many healthcare organizations are not taking the necessary steps to protect medical IoT devices. Alarmingly, 57% do not always change the default username and password for each new connected medical device that is put into use. Additionally, 82% run connected medical devices on old Windows systems. If a security vulnerability is discovered, organizations should patch the device or update its firmware as soon as possible. Unfortunately, 68% of healthcare organizations don’t always update connected devices when a patch is available. However, vulnerabilities and associated patches aren’t always well publicized, which means healthcare IT staff must stay up-to-date on emerging threats to medical IoT devices. Medical IoT security requires proactive and ongoing vigilance. Healthcare practices should conduct routine vulnerability assessments before connecting medical devices to their IT network. They should also keep an up-to-date and accurate inventory of all connected devices plus associated software and firmware, and use software to monitor these devices.
