Software Article: A generalized cascaded linear system model implementation for x-ray detectors.

ABSTRACT:

Purpose

Cascaded linear models are widely used for the development and optimization of x-ray imaging systems, yet no publicly available Python implementation currently exists. We introduce CASYMIR, a flexible and open-source Python package capable of modeling direct and indirect-conversion x-ray imaging detectors under various acquisition conditions.

Methods

We employed a modular software design with generalized frequency-domain expressions for each process in the detection chain, which can be implemented as serial or parallel blocks. The gain factors and other parameters are derived from the detector's characteristics, system geometry, and incident x-ray spectra, all of which can be specified by the user. The signal reaching the detector is propagated throughout the detecti
