description: This paper describes the main features of the Litrani program code for modeling light propagation in various media, both isotropic and anisotropic. In this paper, an algorithm for the propagation of light in the optical system of a scintillation detector based on a CsI crystal is constructed and programmatically implemented using the Litrani code. Based on the developed algorithm, the design of the optical part of the scintillation position-sensitive detector for the gamma camera of single-photon emission reconstructive computational tomography is calculated. The detector is an assembly consisting of a CsI scintillation crystal, an optical glass fiber with a high refractive index, and eight avalanche photodiodes (APDs) glued to it. Predictions are made of the dependence of the coordinate resolution and light collection of the optical part of the detector on the assembly parameters, such as the position of the APD, the refractive index of the fiber. The possibility of correction by the height of the light was discussed.
