Abstract

Sposób wyznaczania parametrów miejsca reakcji kwantu gamma w detektorze scyntylacyjnym tomografu PET, w którym sygnał mierzony w scyntylatorze przekształca się w co najmniej dwóch konwerterach na elektryczne sygnały pomiarowe. Uzyskuje się dostęp do bazy danych (130) zawierającej krzywe kalibracyjne p(S) określające parametry (p) miejsca reakcji w zależności od wartości współczynnika stosunku sygnałów (S), za pomocą procesora (120) oblicza się na podstawie krzywej kalibracyjnej p(S) parametry (p) miejsca reakcji na podstawie wartości współczynnika stosunku sygnałów (S), przy czym współczynnik stosunku sygnałów (S) wyznacza się jako stosunek sygnałów pomiarowych zmierzonych za pomocą co najmniej dwóch konwerterów (111A, 111B; 112A, 112B), których widma wydajności kwantowej różnią się między sobą.The method of determining the gamma quantum reaction parameters in the PET scintillation detector, in which the signal measured in the scintillator is converted in at least two converters into electrical measurement signals. Access to the database (130) containing the p (S) calibration curves specifying the parameters (p) of the reaction place depending on the value of the signal ratio coefficient (S), using the processor (120) is calculated on the basis of the p (S) calibration curve parameters (p) of the reaction site based on the value of the signal ratio factor (S), where the signal ratio factor (S) is determined as the ratio of the measurement signals measured with at least two converters (111A, 111B; 112A, 112B), whose performance spectra quantum ones differ from each other.
