Positron Emission Tomography (PET) allows the in vivo measurement of transport and allocation of recently produced photo-assimilates in plants, which are labeled with $^{11}$C. We operate the plant dedicated system <i>pheno</i>PET which consists of lutetium-yttrium oxyorthosilicate crystals readout with digital Silicon photomultiplier (Digital Photon Counter (DPC) by Phillips). The horizontal Field-of-View (FOV) with a diameter of 180$\,$mm and a height of 200$\,$mm allows the measurements of plants in their natural orientation. Raw data are analyzed offline and reconstructed with Ordinary Poisson Maximum Likelihood Expectation-Maximization (OP-MLEM) provided by PET Reconstruction Software Toolkit (PRESTO). We will present the implemented corrections to reconstruct quantitative images and approaches to speed-up those image reconstructions. |
