A Positron Emission Tomography (PET) scanner is a device widely used in
hospitals to obtain 3D images of the metabolic activity of the body. It
is used for cancer detection, as well as for heart and brain diseases,
and other physiological processes.
PETALO is a project that consists of a PET system based on liquid xenon
(LXe) instead of crystals as the scintillator material. LXe is a very
good candidate for use in PET due to its scintillation properties: high
light yield and fast decay time. PETALO uses SiPMs for readout and fast
electronics from PETsys to be applied in TOF-PET technology.
In this talk, I will first introduce the principles of a PET scanner,
and then I will focus on explaining how our first prototype PETit,
developed following the PETALO concept, works. Finally, I will present
the results on energy and time resolution obtained with this prototype,
as well as the problems we faced in achieving them.
