22 May 2013 | | Abstract: | In this contribution we describe a novel solution for the construction of
Positron Emission Tomograph. We present the device allowing for determination
of the impact position as well as time and deph of interaction of the
annihilation gamma quanta. The device is comprised of scintillation chamber
consisting of organic scintillators surrounding the body of the patient. We
discuss two possible solutions: (i) the tomograph built out of scintillator
strips, and (ii) the tomograph built out of the scintillator plates. The
application of the fast scintillators will enable to take advantage of the
difference between time of the registration of the annihilation quanta. The
invented method will permit to use a thick layers of detector material with the
possibility of measuring the depth of the gamma quantum interaction (DOI) and
the determination of their time of flight (TOF), and will allow for increasing
the size of the diagnostic chamber without a significant increase of costs. The
method is a subject of two patent applications which are based on the
techniques used in the particle physics experiments. | | Source: | arXiv, 1305.5187 | | Services: | Forum | Review | PDF | Favorites | |
