Molecular imaging is aimed at understanding biological processes that support life. In this field, Positron Emission Tomography (PET) dedicated to small animal imaging is among the tools of choice. Compared to clinical scanners, small animal PET presents high challenges regarding the spatial resolution and the sensitivity originating from the small size of animal’s organs. On another hand, the arrival of new radiopharmaceuticals, which own a high specificity on targeted cells, necessitate joining, to the metabolic image acquired from PET, an anatomical image in order to localize the region of interest. Computed tomography (CT) is among these choices. However, the dose injected to the small animal must not affects processes to be studied. The LabPET™ is on a road map that is oriented toward the complete fusion of both PET and low dose CT images using the same detector set and same electronic. The seminar will present the bases that support the LabPET™ design and technological choices made. A wrap-up of all technology involved in the LabPET - analog signal processing as well as real time digital processing – will be exposed for a better understanding to the aims to be reached.
