  • Utah Researchers Developing Focused Ultrasound System to Treat Breast Tumors

    Known as a luminary in medical imaging, Dennis L. Parker, PhD is currently devoting much of his time to focused ultrasound. Parker, a professor of Radiology at the University of Utah and Director of the Utah Center for Advanced Imaging Research (UCAIR), is co-leading the development of a high intensity focused ultrasound (HIFU) system for breast tumors.

    The project’s origins trace back to 2003 when Utah purchased its first MRI scanner from Siemens. “Because the Siemens MRI scanner was very open as far as its software architecture, our students were able to very, very quickly establish a closed feedback loop feeding images out of the scanner into the ultrasound controlling computer that we had at the time,” Parker recalls. This led to the development of a closed-loop MRI guided focused ultrasound system.

    “When Siemens came to visit in 2004, they actually decided to pick up that project and provided some funding,” he notes. At the time, Image Guided Therapy (IGT), a French medical device maker, had just designed a phased-array focused ultrasound transducer.

    “Siemens purchased that device and placed it in Utah as IGT’s first large animal focused ultrasound system,” Parker adds. “Ever since that time, we’ve been working with them.”

    By 2006, Parker and his collaborators decided that the best candidate site for their system would be the breast, and they applied for funding from the National Institutes of Health to develop a prototype. “It was an academic/industrial partnership,” he says. “We were very lucky. We were funded on the first submittal, which is very rare, but we were delighted.”

    His collaborators on the project represent numerous disciplines and several departments at the University of Utah. In addition to Parker, the team includes Robert B. Roemer, PhD from Mechanical Engineering; Douglas Christensen, PhD from Bioengineering; Allison Payne, PhD, Rock Hadley, PhD, Emilee Minalga, PhD, Robb Merrill, PhD and Nick Todd, PhD from UCAIR; Leigh Neumayer, MD from Surgery/Oncology; and many students.

    New breast system has unique features  

    Utah’s system, says Parker, “has a lot of capabilities not found in other breast HIFU systems.” Unique features include the placement of the focused ultrasound transducer. Mounted on flexible bellows made of PlastiDip (an idustrial grade fabrication material), the transducer can be moved into and out of the treatment cylinder as needed. Also unique is that the transducer shoots laterally. The system has a small water box in which the breast is suspended. That box has an array of radio frequency coils around it. According to Parker, this provides “image quality from the MR side [that] is actually very, very good.”

    The system’s other major components are an MR-compatible ultrasound generator made by IGT and a Siemens MRI scanner.

    Now in prototype form, the system has been tested on phantoms and samples. “From the standpoint of something that could ultimately be used to treat breast cancer, I think this is an excellent potential device,” Parker says. “The advantage of HIFU for breast cancer is that it’s totally noninvasive. It has the opportunity eventually to totally eradicate the disease without any surgical intervention at all.”

    A patent application has been filed for the system and further improvements are planned. “There are many problems that still need to be solved,” he notes. “Measuring temperature in fat, which is a major component of breast tissue, has not been solved yet by others. We’ve got a good technique that is starting to work and we’re optimistic that with all these little pieces it’ll be a good system.”

    The team, says Parker, will seek funding to develop modifications that improve image quality and enable the system to treat more aspects of breast disease. “Our new design should be able to treat much more of the disease, including many metastatic lesions,” he notes.

  • Final Patient Treated in FUS Foundation-funded Essential Tremor Study

    The last of 15 patients was treated in mid-December in the world’s first clinical trial using MR-guided focused ultrasound as a therapy for essential tremor. The single-site pilot study, which has been funded by the FUS Foundation, began in February 2011 at the University of Virginia with neurosurgeon W. Jeffrey Elias, MD serving as principal investigator. 

    All study participants are being followed for three-months, and final clinical trial data is expected to be available in March 2012. Elias will present that data at the 2012 American Association of Neurosurgeons meeting, scheduled for April 14-19. 

    Preliminary study data, which was presented by Elias at the 2011 Congress of Neurological Surgeons meeting in October, was highly promising. The study’s first 10 patients experienced a 78 percent improvement in contralateral tremor scores in their dominant hand, as assessed with the Clinical Rating Scale for Tremor (CRST). Patients’ functional activities scores improved by 92 percent, as measured in the ‘Disability’ subsection of the CRST. Elias said that outcomes and complications were comparable to other procedures for tremor, including stereotactic thalamotomy and deep brain stimulation.

  • FUSF-funded Project May Lead to Safer, More Effective Treatment of Breast Cancer

    Mario Ries, Ph.D., a physicist at the Laboratory for Functional and Molecular Imaging in Bordeaux, France, has been intrigued with the notion of combining noninvasive ablation with MR guidance since 1997. Today, his key ambition is help the roughly one to one and a half million people globally diagnosed with breast cancer every year.

    Ries has received a $100,000 research award from the Focused Ultrasound Surgery Foundation to pursue a project he believes will result in a safer and more effective treatment for breast cancer. His objective is to solve the technical drawbacks that cause existing high intensity focused ultrasound (HIFU) transducers – devices that convert energy into sound waves and focus the waves on a target – to damage tissue around the breast, including to the thoracic cage, heart and lungs.

  • World's First Essential Tremor Patient Treated with MR-guided Focused Ultrasound - Patient Interview with Billy Williams



    The last ten years have been challenging for Billy R. Williams of Fort Valley, Virginia. The former Pentagon employee, who survived the 9/11 terrorist attack, has suffered from essential tremor, a progressive and debilitating neurological disorder.

    Medications controlled his tremor for a while, but eventually the shaking became so severe that Williams found it impossible to do anything with his dominant right hand. He was unable to button his shirt, eat without spilling or fill in a crossword puzzle. An avid golfer, he even needed help teeing up his ball. Referred to the University of Virginia for evaluation, he learned about various treatment options and ultimately agreed to participate in a new clinical trial. Funded by the FUS Foundation, the study is assessing the safety and initial efficacy of noninvasive MR-guided focused ultrasound as a treatment for essential tremor.

    On February 25, 2011, Williams became the first essential tremor patient in the world to receive MR-guided focused ultrasound therapy, and the results were dramatically positive.
