Inspired by high-energy physics, our group has pioneered photon counting x-ray imaging and our early research resulted in the Microdose Mammography system later marketed by Philips. We were the first to build a photon counting x-ray imaging system that was adopted in clinical use and approved by FDA. We have also invented portal imaging devices for verification and optimization of radiation therapy. This work was performed in collaboration with the Karolinska Institute in Solna, Sweden and is part of C-RAD, a company listed on the Stockholm NASDAQ OMX stock exchange. We have also been pioneers in the area of multi-prism x-ray focusing devices, first evaluation of the saw tooth lens was published in Nature in 2000. Our current work is focused on photon-counting spectral CT, and we have invented the first photon-counting CT detector to acheive outstanding spectral imaging performance while being able to cope with the very high demands on count rate posed by this modality. This detector is now being further developed by Prismatic Sensors AB, a spin-off company from our group.

In summary the work in our group has led to three spin-off companies and a number of innovations installed in clinics in over 40 countries and used in more than 10 million patient examinations. In independent evaluations of the research in our group we have always received top scores both for scientific excellence and for impact on society. We think it is fair to say that we are one of the leading groups in the world in medical imaging research.
