Si78 PET/CT Brochure


The PET/CT Si78 is a molecular imaging system for sequential Positron Emission Tomography (PET) and X-Ray Microtomography (uCT). The fully shielded scanner, the animal welfare solutions and the experimental workflows are designed to support high throughput translational preclinical research in all field s of nuclear molecular imaging research.

ParaVision 360 software offers the complete solutions from subject & study handling, to scan execution, image reconstruction co-registration & image fusion, data analysis and automatic report generation. It easily links imaging data to the most advanced quantitative PET data analysis and kinetic modelling features offered by the PMOD biomedical image quantification software of Bruker.
