A SciSchema.org Process Schema

Domain: Imaging & Measurement
Schema: Iterative X-ray CT Reconstruction (ART/SIRT + MBIR Family) Master Schema
Current version: 1.0.0

Iterative tomographic image reconstruction is a digital guess-and-check method used to create internal 2D or 3D images from raw X-ray data.

Properties from Iterative Tomographic Image Reconstruction

The table below lists the top-level properties of this master schema. Each property may contain more detailed nested fields in the JSON Schema representation.

Property Expected Type Description Required
metadata Object General identifying information about the reconstruction study, schema version, modality, and reconstruction method family. No
acquisition Object Acquisition configuration describing scan geometry, X-ray spectrum, projection sampling, and dose-related constraints. Yes
physics_model Object Physical forward model used to represent X-ray transport, attenuation, system response, scatter, and correction effects. Yes
statistical_model Object Statistical assumptions used to describe measurement noise and the data likelihood in the reconstruction objective. Yes
preprocessing Object Corrections and transformations applied to raw projection data before iterative reconstruction. No
initialization Object Initial image, volume, or prior information used to start the iterative reconstruction algorithm. No
objective_function Object Optimization objective defining the data fidelity, regularization, and constraints minimized or maximized during reconstruction. Yes
regularization Object Regularization strategy and associated parameters used to stabilize reconstruction and encode prior assumptions. No
solver Object Numerical optimization or iterative update procedure used to solve the reconstruction problem. Yes
dynamic_reconstruction Object Settings for reconstruction of time-varying objects or scans affected by motion. No
postprocessing Object Image processing operations applied after reconstruction to improve, analyze, or prepare the reconstructed image volume. No
evaluation_metrics Object Quantitative metrics used to evaluate reconstruction accuracy, image quality, contrast, resolution, and artifacts. Yes
reconstruction_output Object Final reconstruction products and metadata describing the generated image volume and uncertainty outputs. Yes
