On the Determination of the Resolution Index of a Gamma Camera

L’étude tâche d’interpréter les différences des indices de résolution de gamma caméra obtenues expérimentalement et calculées. Les erreurs de mesurage et les conditions de validité des formules utilisées dans les calcules sont discutées. On a pu obtenir un agréement des deux méthodes et une confirmation théorique. On suggert de déterminer quelque condition de mesurage ou de remplacer les méthodes de mesurage par de calcul.

Summary

The aim of the work was to explain the differences in resolution indexes of a gamma-camera determined experimentally or calculated. The measurement errors and the conditions of validity of calculation formulas were discussed. Full agreement for both methods was obtained and confirmed theoretically. The suggestion was made to determine some of the measurement conditions or to replace the measurement method by calculations.

Das Ziel dieser Arbeit war es, die Differenz zwischen dem experimentellen Teil bestimmter und dem berechneten Auflösungsindices einer Gammakamera zu erklären. Die Meßfehler und die Bedingungen für die Gültigkeit der Berechnungsformeln werden diskutiert. Volle Übereinstimmung beider Methoden wurde erzielt und theoretisch bestätigt. Es wird vorgeschlagen, einige der Meßbedingungen zu bestimmen oder die Messung durch Berechnungen zu ersetzen.
