Richard Mallozzi, Ph.D., Chief Technical Officer




Richard is a physicist with extensive experience in MRI systems, applications, physics, and engineering. Richard earned an A.B. in Physics from Harvard University, and a Ph.D. in Physics from University of California at Berkeley in 1998, where he studied high-temperature superconductivity. After graduating from U.C. Berkeley, Richard joined GE Global Research as a Magnetic Resonance Scientist, where he worked on diverse projects ranging from MRI acoustic noise reduction, interventional MRI, gradient and RF coil development, and applications of MRI to neuroimaging.

While at GE Global Research, Richard collaborated with the Phantom Laboratory and GE scientist Daniel Blezek to develop the phantom and analysis technique that formed the basis of the  control method. Richard joined ONI Medical Systems in 2007, where he helped develop the first high-field (1.5 Tesla) commercial extremity MRI system.

Richard joined Phantom Laboratory and Image Owl in 2014, where he works on a variety of physics and application issues pertinent to medical imaging.






Hildur Ólafsdóttir, Ph.D, Vice President

Hildur received her MSc.Eng degree in Applied Mathematics from the Technical University of Denmark in 2004 and  her PhD degree in Applied Mathematics from the same university with the specialization Medical Image Analysis in April 2008. Her thesis work involved developing algorithms for Craniofacial CT Image registration and statistical analysis of deformation fields.

After graduating, Hildur did two years of postdoctoral research working on automatic analysis of cardiac MRI. Further, Hildur has worked as a consultant, developing software for automated analysis of CT images, for the Danish Meat Research Institute (now Danish Technological Institute) and the 3D Craniofacial Research Lab.

Hildur joined Image Owl in March 2011.  Her  responsibilities included managing the agile scrum software development processes within the company as well as managing the image processing team. Her technical responsibilities include developing algorithms for automatic recognition, segmentation and processing of phantom images in addition to data analysis and statistics. Hildur currently serves as CEO of Raforninn.




Joshua Levy, Chief Operating Officer

Josh has extensive experience with phantom design and manufacturing.  After working in the medical imaging phantom field for over ten years he started The Phantom Laboratory, Incorporated in 1989. Along with management of the company, Josh has worked with renowned scientists and physicists in the development of numerous phantoms used in the medical imaging and radiation field.  Along with several patented designs developed for The Phantom Laboratory, he has also developed a host of custom phantoms used by scientists and engineers in research and development areas. Josh also has developed a number of OEM phantoms, manufactured by The Phantom Laboratory, for multiple medical equipment manufactures.

Josh, along with his partners, seeing the value and need of cloud-based quality and image processing services, founded Image Owl in 2006.

Advisory Board









David Goodenough, Ph.D., CT Physicist

First Studying Radiation Therapy Physics (Radiological Physics) with two of the grandfathers of Medical Physics, Professors Lester Skaggs and Larry Lanzel, David went on to work in the emerging fields of Radiological Image Analysis working under his Ph.D. Thesis Advisor, Kurt Rossman and Lee Lusted, MD leading to his thesis on the use of ROC Analysis for medical imaging. He was awarded his Doctorate in Medical Physics from University of Chicago 1972, where he then served on the faculty of the Radiology Department working with Kunio Doi, Charles Metz, and other distinguished faculty in the Center for Radiological Image Analysis.

He subsequently moved on the faculty of The Johns Hopkins University Department of Radiology working in Radiology and Nuclear Medicine with Henry Wagner and other colleagues.  He was recruited to the George Washington University in 1975 to become the Director of the Division of Radiation Physics. He served as a tenured Professor of Radiology at the GWU, and became Co-Director of the Institute for Medical Imaging and Image Analysis before being awarded Emeritus rank in 2010.  While at George Washington University Medical School, David pioneered many methods in the field of CT Image Quality measurement with his work on one of the original EMI CT scanners. In the end of the 1970′s he developed the first Catphan® phantom and has been the scientific driver for the six generations of phantoms that have followed. In 1984 David took a sabbatical year in Europe to study MR imaging resulting in additional test phantom development in the field of MRI.  David also developed the first comprehensive automated CT QA measurement software for CT and MRI, and  worked as a consultant to The Phantom Laboratory in the fields of Medical Imaging including CT, MRI, PET, SPECT.

Along with a wide array of papers, presentations and courses, David has been involved with extensive medical imaging       testing providing him with a truly practical knowledge complementing his scientific knowledge.
