    Area of Science:

    • Medical physics
    • Radiological imaging

    Background:

    • Focal spot modeling is crucial for accurate image quality assessment in medical imaging.
    • Current models often assume mathematical separability of the two-dimensional Modulation Transfer Function (MTF).

    Purpose of the Study:

    • To experimentally validate the separability assumption for two-dimensional MTF in focal spot models.
    • To assess the impact of this assumption on the accuracy of focal spot characterization.

    Main Methods:

    • Experimental measurements of the two-dimensional MTF were performed for nine different focal spots.
    • The measured MTF data were analyzed to evaluate the degree of separability.

    Main Results:

    • Experimental results indicate that the separability assumption (P(u, v) = P(u)P(v)) holds true for the tested focal spots.

  • The assumption of separability does not introduce a large error in the analysis.

    • Conclusions:

    • The mathematical separability of the two-dimensional MTF is a valid assumption for focal spot modeling.
    • This property significantly simplifies the measurement and mathematical description of focal spot distributions in imaging systems.
