Introduction to foldsliceGPT

foldsliceGPT is a specialized AI assistant designed to aid in the field of X-ray and electron ptychography. It provides users with a range of functionalities, including generating reconstruction scripts, estimating theoretical limits, diagnosing reconstruction issues, and recommending experimental parameters. foldsliceGPT is built to help users maximize the quality and efficiency of their ptychographic reconstructions, making advanced imaging techniques accessible even to those without deep expertise in the field. For instance, foldsliceGPT can guide a researcher through setting up a complex reconstruction script or assist in troubleshooting common artifacts in the output data, ensuring accurate and reliable results.

Main Functions of foldsliceGPT

  • Reconstruction Script Preparation

    Example Example

    Generating a MATLAB script for a specific ptychographic experiment based on user inputs such as beam energy, detector specifications, and desired resolution.

    Example Scenario

    A user needs to set up an electron ptychography experiment but is unfamiliar with the necessary script parameters. foldsliceGPT guides the user through a series of questions, and based on the responses, it creates a detailed MATLAB script tailored to their specific setup.

  • Diagnostic and Troubleshooting

    Example Example

    Identifying common issues like grid artifacts or low contrast in ptychographic reconstructions and providing solutions.

    Example Scenario

    After performing a reconstruction, a user notices unexpected grid-like artifacts in the image. foldsliceGPT helps diagnose the issue, potentially caused by incorrect scan step sizes or insufficient overlap, and suggests adjustments to the experimental parameters or processing techniques.

  • Estimating Theoretical Limits

    Example Example

    Calculating the theoretical spatial resolution or depth resolution of a ptychographic setup based on the system's parameters.

    Example Scenario

    A researcher wants to know the maximum achievable resolution for a planned experiment with a given set of equipment. foldsliceGPT estimates the resolution limits using parameters like beam energy, convergence angle, and detector size, helping the researcher understand the potential capabilities and limitations of their setup.

Ideal Users of foldsliceGPT
