Cross section measurements for production of positron emitters for PET imaging in carbon therapy

In light ion beam therapy, positron ({\ensuremath{\beta}}^{+} emitters are produced by the tissue nuclei through nuclear interactions with the beam ions. They can be used for the verification of the delivered dose using positron emission tomography by comparing the spatial distribution of the {\ensuremath{\beta}}^{+}emitters activity to a computer simulation taking into account the patient morphology and the treatment plan. However, the...
