Hybrid x-ray/MR system and other hybrid imaging modalities
Author(s): Norbert J. Pelc

Paper Abstract

The past few decades have seen phenomenal growth in medical imaging technologies and their impact in biomedicine. This trend will continue, and indeed expand with the development of new techniques. However, another development likely to have major importance is the development of systems offering combined modality imaging in the same platform. Such hybrids include PET/CT, PET/MRI, SPECT/CT, and x-ray/MR systems, and offer not only the convenience of access to multiple modalities in the same session, but more importantly, synergistic uses in which the combined modality is more than the simple sum of previous methods. A simple example is the use of CT data for attenuation correction in PET and SPECT imaging, which is greatly facilitated in a hybrid system. In our own work, we have developed a hybrid x-ray/MR system for image guided interventions. It brings together the high spatial and temporal resolution of x-ray fluoroscopy with the 3D imaging capabilities, soft tissue contrast, and sensitivity to physiological processes of MRI. System development required exploration of a number of interesting problems, including the effect of high magnetic fields on x-ray tubes. The system has been used for several diagnostic and minimally invasive applications, including biopsies, arthrograms, and TIPS procedures.
