ABSTRACT
The standardization of images derived from different medical modalities should be ensured when image fusion brings essential information and hybrid scanners are not available. The aim of this study was to show that precise image fusion standardization can be obtained using special and unique multimodal heart phantom (MHP) which is compatible with all applied diagnostic methods. MHP was designed and constructed according to International Commission on Radiological Protection reports, scanners requirements and personal experience. Three different types of acquisitions were done: physiological perfusion, myocardial ischaemia and intestines artefacts. The measurements were done using different modalities (single photon emission computed tomography (SPECT), positron emission tomography (PET), MRI, CT) as well as hybrid scanners (PET/CT, SPECT/CT). It was shown that MHP can be used not only for improvement of image fusion standardization protocol but also for verification of proper implementation of the fusion protocol in hybrid scanners.
