Hitachi Highlights Widest-Bore MRI, New 128-Slice CT
Interview with John Carroll, M.D., director of interventional cardiology, Robert Quaife, M.D., director of advanced cardiac imaging, and James Chen, Ph.D., associate professor of medicine and director of the 3-D imaging lab at the Cardiac and Vascular Center at the University of Colorado Hospital.
They explain how the program now incorporates transcatheter aortic valve replacement (TAVR), transcatheter mitral valve repair, transcatheter mitral valve replacement (TMVR), left atrial appendage (LAA) occlusion and transcatheter closure of holes in the heart. The heart team in this video stressed the need for advanced imaging to plan and guide the procedures.
They explain how the center developed its own 3-D imaging software and worked with Philips healthcare to commercialize some of the technologies, including the EchoNavigator system used to fuse live angiography with live transesophageal echo (TEE).
The Accelerated move to Big Data Analytics and Cloud Are Leaving Some Vendors Behind.
What differentiates this from all previous revolutions, like the industrial revolution and the information revolution, is that it goes beyond the ability of technology to augment our physical capabilities to build things or to communicate things.
AI, machine learning and deep learning will help to solve many societal problems, like climate change, crime, disease, and the challenges of enhancing the quality of life and standard of living in megacities.
Quantum computing takes advantage of the strange ability of subatomic particles to exist in more than one state at any time. I am not about to provide a tutorial here on quantum computing except to refer you to wikipedia.
While quantum computers are suited for these types of problems, they are not replacements for standard computers which are better suited for transactional problems or playing Youtube videos.
Many are dependent on super conducting materials which require temperatures in the near absolute zero temperature range to minimize the movement of electrons and atoms.
The D-Wave quantum computer referenced above, is cooled to 15 millikelvin, which is approximately 180 times colder than interstellar space.
This computer can solve these problems without the need for a quantum computer and super conducting materials.The key to solving these problems is the use of a mathematical model called the Ising Model
(Annealing is a method for removing distortions on the inside of iron and steel by slowly cooling it after heating it to high temperatures.) The computer that Hitachi Invented reproduces the convergence behavior through a CMOS circuit.
However, today, quantum computers need to maintain near-zero temperatures and remain free from magnetic interference, thermal noise, and mechanical vibration in order for qubits to maintain superposition—the dual states of both 0 and 1—which forms the basis of quantum calculations.
Its ability to factor large prime numbers allows them to break asymmetric encryption which is used by internet communications schemes like SSL and its blazing speed could brute force symmetric encryption which is used for encryption of data at rest.
If we believe that quantum computers will be available in the next 10 years, we need to think about protecting the data that we encrypt today to ensure that it is protected beyond the time that quantum computers become available.
While researchers are looking at how to prevent this with future quantum proof encryption schemes, NIST recommends that we increase the key sizes of symmetric encryption and hashing algorithms for data at rest to make it harder for brute force attacks.
The current key size in use is 256, which represents 2^256 which is an astronomically high number of combinations, however a quantum computer with enough Qubits could blow through that in an instant.
