Future Trends in Nuclear Medical Imaging

摘要: Abstract. Continuous efforts to integrate recent research findings for the design of different geometries and various detector technologies single-photon emission computed tomography (SPECT) positron (PET) scanners have become goal both academic community nuclear medicine industry. As PET has more interest clinical practice, several trends seem developed. Systems are being designed “low cost” applications, very high-resolution just about everywhere in-between. All these systems undergoing revisions in hardware software components. The development dual-modality imaging is an emerging field. One major advantages that SPECT/PET data intrinsically aligned anatomical information from X-ray CT without use external markers or internal landmarks. On other hand, combining with Magnetic Resonance Imaging (MRI) technology scientifically challenging owing strong magnetic fields. Nevertheless, significant progress been made resulting a prototype small animal scanner coupled three multi-channel photomultipliers via optical fibers so can be operated within conventional MR system. Thus, there many paths pursued - which ones likely main stream future commercial systems? It will interesting, indeed, see what most popular future. This paper briefly summarizes state-of-the art developments dual-imaging devices. Future prospects also discussed
