MEASUREMENTS OF IONIZING RADIATION: INTEGRATING ENCODING SYSTEMS FOR RECORDING IONIZING RADIATION. OBLIQUE INCIDENCE OF RADIATION

摘要

An investigation is mad eof the influence of the factor of oblique incidence of radiation on the quality of reconstructed images when utilizing integrating encoding systems for measuring ionizing radiation with plane multipinhole encoding collimators. The results are given of a numerical calculation of an instrumental function which takes this factor into account. Four methods for compensating the factor of oblique incidence of radiation are considered. Recommendations are formulated for choosing the type and method of construction of the collimator used.
