Assessing the performance of detectors is important for the design of new or the optimization of existing systems. Information transmission in detectors can be quite complex, including various interconnected mechanisms like amplification/reduction or scatter/crosstalk. The state-of-the-art approach is to decompose the detection process into a sequence of steps that can be described mathematically. We propose an alternative approach based on a Monte Carlo model for the response of the surrounding detector pixels to photons impinging at various locations of a pixel. Using this model, the full statistics of the detector including the pre-sampling Modulation Transfer Function (MTF), the Noise Power Spectrum (NPS) and the DQE can be determined in a straightforward manner. The purpose of this paper is to describe the procedure and to demonstrate the simplicity and power of the approach for a simple toy detector. The full version will also show simulation results for realistic detectors.
