About Wollin Ventures
Engineering New Possibilities in Magnetic Resonance
Wollin Ventures, Inc. is a Florida-based engineering corporation focused on magnetic resonance technology development and intellectual property.
Founded in 1994, the company has pursued inventions that extend the capabilities of magnetic resonance beyond conventional imaging. Its work has explored the applications of magnetic resonance, such as:
- How magnetic resonance may be used to measure electrical properties
- Analyzing material movement and composition
- Improving the extraction of information from MR signals
- Investigating applications in both medicine and industry.
At the center of this work is Ernest Wollin, whose combined background as a physician, radiologist, electrical engineer, and professional engineer provides a distinctive perspective on technical problems.

Research & Medical Imaging
Exploring New Information Within Magnetic Resonance
Dr. Wollin originated the concept of Magnetic Resonance Electrical Impedance Mammography (MREIM), an innovative approach to breast cancer detection.
MREIM explores the combination of magnetic resonance imaging with measurements related to the electrical conductivity of tissue.
Research associated with the technology has included theoretical analysis, computer simulation, experimental work, and breast-imaging applications. Academic research at the University of South Florida documented the development of the technique by Wollin Ventures in conjunction with the H. Lee Moffitt Cancer Center & Research Institute. MREIM was the subject of the dissertation entitled, “Advances in Magnetic Resonance Electrical Impedance Mammography” by then University of South Florida Ph.D. candidate Nataliya Kovalchuk. Dr. Kovalchuk is now a Clinical Professor at Stanford Radiation Oncology department and an Adjunct Professor at MD Anderson Cancer Center.
The work reflects the broader philosophy behind Wollin Ventures: using established magnetic resonance principles in new ways to uncover additional measurable information.
