Date posted: 28/06/2005 Ultrasound, that mainstay of medical imaging, may one day be used to wipe out brain tumours. An Iowa State University research team led by Viren Amin, a scientist at Iowa State's Centre for Non-destructive Evaluation and an adjunct professor of electrical and computer engineering, will study the feasibility of using high-intensity focused ultrasound as a non-invasive way to treat brain tumours. In medical applications, high-intensity focused ultrasound can precisely destroy cells by generating heat, but it can do so without destroying cells outside the focused area. "You want to 'cook' only the tumour and not the surrounding cells," Amin said. Researchers are trying to develop imaging and visualisation tools to integrate MRI and ultrasound images as well as simulations of ultrasound beams through tissues and of the heat generated at the focus. These brain simulations will be used to precisely guide ultrasound beams to their targets without destroying vital cells. "It's a true multidisciplinary project," said Amin, who has degrees in medicine and biomedical engineering. Other team members include Roberts and Thompson of the Centre for Non-destructive Evaluation; Mark Bryden, a faculty fellow in the Virtual Reality Applications Centre and an ISU associate professor of mechanical engineering; and Scott McClure, an ISU professor of veterinary medicine. Other collaborators include Timothy Ryken, a doctor in the department of neurosurgery and radiation oncology at the University of Iowa in Iowa City; and Shahram Vaezy, an expert in high-intensity focused ultrasound from the University of Washington in Seattle.
