This study introduces a mathematical optimization technique to balance blurring and artifact reduction in tomography. The method effectively reconciles these conflicting factors for improved image quality.

Area of Science:

Medical Imaging
Image Processing
Computational Science

Background:

Tomography involves imaging by sections or sectioning.
Increasing blur in nonfocused layers can introduce artifacts.
Balancing blur and artifact reduction is crucial for image fidelity.

Purpose of the Study:

To develop a mathematical optimization technique for tomography.
To reconcile the trade-off between blurring nonfocused layers and introducing artifacts.
To improve the effectiveness and fidelity of blurring in tomographic imaging.

Main Methods:

Employed a mathematical optimization technique.
Utilized definitions of blurring effectiveness and fidelity based on the transfer function.
Generated a sequence of spread functions for optimal combination of aspects.
