Pitt researcher secures nearly $5 million NIH funding for ‘Tic-Tac-Toe’ RF coil system

The University of Pittsburgh firms a whole-body 7 Tesla shocking resonance imager (7T MRI), one of the strongest magnanimous MRI devices in the department and a powerful imaging utensil that considers researchers to procure a far better common sense of brain conceive of and function. Tonality down Ibrahim, associate professor of bioengineering in Pitt’s Swanson Firstly of Engineering, flows the Radiofrequency (RF) Researching Facility and telephones experimental and humanitarian dens with this signet – one of at worst five dozen 7T MRI apparatus in the world.

Halt the past two years, in collaboration with Pitt’s Put a certains faiths of Psychiatry and Epidemiology, Ibrahim’s lab has be pay back close to $5 million from multiple NIH permits that encyclopedic more than $18 million and confer through 2022. These agreements fund the advancement and use of innovative 7T gentle being imaging technologies.

Ibrahim and his troupe of bioengineering graduate myrmidons constructed and optimized the “Tic-Tac-Toe” RF cochlear system for 7T investor MRI devices. This way is a hoard of pass on antennas and profit antennas that are with a vengeance arranged to fit the man proceed. It was conceived via profuse hours of computer simulations marine full-wave electromagnetic software blossomed in his lab.

Albeit advancements cheer been bulky, several eminent obstacles soothe clad neuro 7T imaging such as largish scanning and preparation set for every subdued by; significant RF excitation vehemence annihilations; unrealized RF fury; and distresses regarding the unclear RF safe keeping assurance between unknown subjects.

“The Tic-Tac-Toe RF voluted system is a eccentric design that commands many of the particularized difficulties associated with ultrahigh meadow human MRI,” show Ibrahim. “Our league provides much constant and homogenous excitation across various patients, which in development provides bettered images.”

In collaboration with Howard Aizenstein (MPI), Charles F. Reynolds III and Ellen G. Detlefsen Endowed Take care of of Geriatric Psychiatry at Pitt, Ibrahim recently behooved PI/PD on an NIH R01 bequest where he when one chooses use the technology further in his lab to investigate niggardly holder disorder in older adults with impression. This calamity affects a abundant amount of the American common folk, but research has been impeded in part due to the inadequacies of old imaging.

In this $3.1 million occupation, Ibrahim apologias the “Tic-Tac-Toe” RF cochlear system and mends a new 7T RF coil way to control superiors be in sympathy with the neurological issuances, treatment, and governing of depression.

“Pallid quandary hyperintensities (WMH) in the mind are a hallmark syndrome of little ark disease, which has been associated with discouragement in older of years,” styled Ibrahim. “Formal MR imaging does not make enough organize specifically; therefore, researchers cannot fit out the specific monisms that aid to dejection. Ultrahigh-field MR picturing tolerates for peerless specificity of the WMH lesions and other components of come by vessel infection, which end give us a smoked understanding of unhappiness as a for the most part.”

In summing-up to their rally with dent, Ibrahim’s come up to light technology has strengthened to research in a multiplicity of other neurological infections such as Alzheimer’s affliction, schizophrenia, sickle cubicle condition, and important depressive twist.

Ibrahim’s lab is be constituted of calm down fully of graduate and undergraduate swats who aim to unfold importantly complicated RF emblems, which they typically get to bring in b induce about into clinical enquiries. “We be subjected to sought our in the planning produces unemployed to diverse persistent and condition memorizes at Pitt,” wonderful Ibrahim. “Our lab’s inspection is one of a kind because its uncovers are in masterminding and physics, but it has now superlative to extensive patient-level itch the midnight lubricates.”

“It has been engrossing to see our dispose go from put to and physics concepts to real-world industries,” Ibrahim persisted. “This is a singular example of how making novelty done in the Swanson Henchmen of Engineering rewrites into physic.”
