Ralph, a founding Director of VHT, has been at the forefront of the digital breast imaging field for over 25 years. Initially a research scientist at the University of Oxford, Ralph’s innovative work in quantitative breast imaging technology led him to form first OXIVA Limited and then Mirada Solutions with Professor Sir John Michael Brady. Under Ralph’s leadership Mirada became the number-one provider of image registration and fusion tools before being acquired by CTI Molecular Imaging Inc. and later Siemens Medical Solutions USA, Inc.
Before founding VHT in 2009, Ralph consulted for many of the world’s top medical imaging companies, including R2, Siemens, Hologic and Dexela, as well as many leading breast screening programs. During this time, he continued his academic research as part of an international circle of collaborators.
Ralph is the author of numerous articles and, with Brady, the seminal book Mammographic Image Analysis. As CEO of VHT, Ralph is dedicated to providing the most accurate measurements possible of breast composition (“breast density”) in order to improve the health outcomes of women around the world.
