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.A method of determining parameters of a gamma quantum reaction site in a PET tomograph scintillation detector, wherein the signal measured in the scintillator is converted in at least two converters into electrical measurement signals. Access is obtained to a database (130) containing calibration curves p(S) defining reaction site parameters (p) depending on the value of the signal ratio coefficient (S), using a processor (120) to calculate, on the basis of the calibration curve p(S), the reaction site parameters (p) based on the value of the signal ratio coefficient (S), wherein the signal ratio coefficient (S) is determined as the ratio of measurement signals measured using at least two converters (111A, 111B; 112A, 112B) whose quantum efficiency spectra differ from each other.
