Professor McAleavey Awarded Patent
A conventional ultrasound image (left) is insensitive to the
stiffnessor shear modulus of tissue, as shown in this image of a test object with a 1 cm stiff inclusion. The greater modulus of the inclusion is clearly revealed in the SMURF image (right).
Professor Stephen McAleavey of the Department of Biomedical Engineering has been awarded a new U.S. Patent. The patent, number 8,225,666, is titled
Ultrasound Imaging of Tissue Stiffness by Spatially Modulated Acoustic Radiation Force Impulse.The patent details a new ultrasound elastography technique, termed SMURF imaging, that uses acoustic radiation force to quantify tissue stiffness. Tissue stiffness is a known indicator of disease. Thus, this new technology will be useful clinically to noninvasively diagnosis fibrosis, cancerous tumors, vascular diseases, and monitor the progress of ablation therapies. Professor McAleavey is an active member of the Rochester Center for Biomedical Ultrasound (RCBU).

RCBU Student Members Attend Physical Acoustics Summer School
RCBU student members, Himanshu Shekhar and Karla Mercado, applied to and were selected to attend the Physical Acoustics Summer School (PASS) at the University of Mississippi National Center for Physical Acoustics from May 23-29. The purpose of PASS is to bring intermediate and advanced graduate students, distinguished lecturers, and discussion leaders together to discuss a wide variety of subjects in Physical Acoustics. Participation is limited to 50 attendees and it is a very selective process. Himanshu Shekhar is a Ph.D. candidate in ECE working with Professor Marvin Doyley in the area of biomedical imaging using targeted ultrasound contrast agents. Karla Mercado is a Ph.D. candidate in BME working with Professor Diane Dalecki on a project to develop high-frequency ultrasound techniques to noninvasively characterize the material, structural, and biological properties of engineered tissues.

John Nicosia wins award at UR Research Expo
John Nicosia presenting his research at the UR Research Expo.
John Nicosia (BME class of 2013) was awarded the Professors' Choice Award for Undergraduate Research in Engineering and Applied Sciences at the University of Rochester Undergraduate Research Expo held on April 20, 2012. John was recognized for the research he presented in his poster titled
Techniques to Quantify Cell Proliferation in Three-Dimensional Hydrogels.His mentors for this research and co-authors on the poster are Professor Diane Dalecki and Professor Denise Hocking. John has been involved in research in biomedical ultrasound in the Dalecki Lab since his freshman year. John will be continuing his research to advance new applications of ultrasound in cell and tissue engineering though the summer and senior year as a Xerox Fellow in the Dalecki Lab.

Obesity during pregnancy puts women at higher risk of a multitude of challenges. But, according to a new study presented earlier this month at the American Institute of Ultrasound in Medicine annual convention, fetal growth restriction, or the poor growth of a baby while in the mother’s womb, is not one of them. In fact, study authors from the University of Rochester Medical Center found that the incidence of fetal growth restriction was lower in obese women when compared to non-obese women.

John Nicosia and Laura Hobbs Awarded UR/Xerox Undergraduate Research Fellowships
BME undergraduate students John Nicosia and Laura Hobbs have been awarded UR/Xerox Undergraduate Research Fellowships. Both students will be working in the laboratory of Diane Dalecki, RCBU Director and Associate Professor of Biomedical Engineering. Research projects will focus on developing ultrasound technologies for cell and tissue engineering applications. The SEAS Xerox Fellowship Program is a highly competitive program that provides engineering students with research experience. The program begins during the summer preceding the senior year, and continues as an independent research course in the fall and spring semesters of the senior year.

Dr. Maria Helguera Receives Promotion
RCBU member Dr. Maria Helguera has been promoted to associate professor of Imaging Sciences with tenure at RIT. Dr. Helguera is a Principal Investigator in the Biomedical and Materials Multimodality Imaging Lab in the CFC Center for Imaging Science at RIT. Starting in July 2012, she will become the academic coordinator of the undergraduate program in Imaging Sciences. She teaches numerous courses, including Introduction to Medical Imaging Systems (graduate), Research Practices (undergraduate), Statistical Tools for Imaging (undergraduate), and Imaging Science Freshman Imaging Project (undergraduate).
A long-time member of RCBU, Dr. Helguera is an expert in ultrasound tissue characterization techniques. She has developed ultrasound techniques to quantitatively characterize properties of a wide range of biological and non-biological materials. Through a recent collaboration with Dr. Diane Dalecki and Dr. Denise Hocking, Dr. Helguera is investigating high-frequency ultrasound techniques for characterization of three-dimensional engineered tissues.

Richard E. Waugh, professor and chair of the Department of Biomedical Engineering, and James M. Farrar, professor of chemistry, have been elected Fellows of the American Association for the Advancement of Science (AAAS). The AAAS is the world's largest general scientific society and the publisher of the journal Science.
The AAAS recognized Waugh for his
distinguished contributions to the study of cell and membrane mechanics and for leadership in biomedical engineering.Waugh received a Ph.D. in bioengineering from Duke in 1977 and came to Rochester in 1980. His laboratory has historically been one of the leading facilities for investigating red blood cell mechanical properties and the stability of biological membranes.

Marvin Doyley (ECE and BME) was invited to write a topical review article by the journal Physics in Medicine and Biology (PMB). This article, titled Model-based elastography: A survey of approached to the inverse elasticity problem, was published online in January and was selected by PMB as their featured article. The review is also featured as Editor's Choice by Medical Physics Web.
The article reviews current approaches to elastography and documents efforts to develop elastography within the framework of solving an inverse problem, so that elastography may provide reliable estimates of mechanical properties of tissue. Dr. Doyley is a member of the Rochester Center for Biomedical Ultrasound (RCBU).
