Simultaneous magnetic resonance imaging (MRI) and positron emission tomography (PET) enable simultaneous acquisition of anatomical and functional imaging. Currently, separate reconstruction of MRI and PET images is performed. Recently, joint reconstruction of MRI-PET has been explored using gradient based priors, which have the risk of infusing cross-modality artefacts. We propose a coupled MR-PET patch based dictionary prior for the joint reconstruction of MRI and PET contrasts.

ConferenceIEEE Nuclear Science Symposium and Medical Imaging Conference 2018
Abbreviated titleNSS/MIC 2018
OtherThe 2018 Nuclear Science Symposium will offer an outstanding opportunity for scientists and engineersworking in the field of radiation instrumentation to meet together, present new results and discuss the latestdevelopments in their field, not only with their own colleagues, but also with colleagues from related fields suchas medical imaging and room temperature semiconductors. The NSS is held contemporarily with the 2018Medical Imaging Conference and the 25th International Symposium on Room Temperature X Ray and GammaRay detectors, which brings together one of the largest collection of detector scientists and experts in the world. This very international venue, which is being held for the first time in Sydney, Australia, promises to be one of best programs in the long history of this conference.

The NSS program emphasizes the latest developments in detector technology, radiation detection, detector materials, new instrumentation techniques, and their implementation in high energy and nuclear physics,astrophysics, accelerators, national nuclear security, and many other applications in various types of radiation environments. Joint sessions will be held with the MIC and RTSD, along with a number of special topic workshops covering areas of specific interest. Short Courses on a variety of topics of interest to the NSS community are also being offered.
