Nicholas Dwork, PhD, assistant professor in the Department of Biomedical Informatics at the University of Colorado School of Medicine, has actually filed a provisionary patent for an innovation that might increase scan speeds of three-dimensional magnetic resonance imaging (MRI). The invention could cause faster outcomes, increase the clinical applications of MRIs, and eventually improve patient care.
Complex mathematics and engineering are associated with creating pictures of internal organs and tissues when clients go into the magnetic tube of an MRI machine. Any motion by the patient can corrupt the images, and the scan can take an hour or longer. Throughout this time, the machine makes loud noises as radio waves reverberate off bodily structures to develop images. Since the field of view– the part of space that is imaged– is normally rectangular, the radio waves also bounce off locations outside the body. This is where Dwork’s technology enters play.
Expect you understood absolutely nothing at all about the image you were trying to make. Because case, you would require an optimum amount of details in order to make the image, which implies gathering an optimum quantity of data. How can we lower the quantity of data we require? If we had more info about the picture we were making, then we would not need as much information.”

His approach changes the tasting pattern developed by the device’s electromagnetic fields.
“They’re called pulse sequence diagrams,” Dwork describes. “Think about the MRI as a musical instrument. Just like a musical instrument, they can play various tunes. You may think about it as sheet music for the MRI device.”
He collaborated with faculty in the Department of Radiology to establish applications for the programming and will continue to refine the innovation through his own research.
“Mostly, this means combining this specific technique of making MRI quicker with other innovations to make scanning extremely quick,” he says. “These other innovations include what is known as partial Fourier tasting, parallel imaging, compressed noticing, and deep knowing.”
Dwork estimates that his approach to MRI scans could reduce times by about 25 percent, making it possible for medical professionals to get outcomes much faster and reducing clients’ time in the MRI tube. He pictures the much faster scans being utilized for a multitude of purposes, potentially broadening MRI utilize to really kids and pregnant patients. He wishes to research its application to twin-to-twin transfusion syndrome, an unusual condition in which twin fetuses share one placenta and a network of blood vessels. A fast, precise MRI can assist a cosmetic surgeon in cauterizing the blood vessels in the placenta to resolve the condition and enhance results for the fetuses.
Dwork, who has actually concentrated on applying advanced mathematics to medical problems throughout his profession, says his work would not be possible without the support he’s discovered at CU. As a member of the Affiliate Faculty Program of the Applied Mathematics Department at CU Stone, he offers discussions on medical problems to the math department while likewise bringing unique mathematical insights to CU Anschutz Medical Campus. He’s also dealing with CU Innovations, the innovation commercialization and venture development workplace at CU Anschutz, to market the creation to imaging companies and establishing research in the clinical setting.
“For the kind of work that I like to do, which is applying advanced mathematics to medical problems, CU Anschutz is the ideal location to be,” he states. “I’m incredibly grateful to the Department of Biomedical Informatics for providing me this professional opportunity and providing me with many resources to maximize the possibility of my success.”
