Scanner Components and Function

Describes CT scanner components: X-ray tube, detector arrays, gantry rotation systems, and patient table mechanics. Explains how each component contributes to image formation and how component selection affects spatial and temporal resolution and dose.

Image Reconstruction Concepts

Accessible explanations of filtered back projection, iterative reconstruction, model-based reconstruction, and deep-learning denoising. Explains how reconstruction kernels, slice thickness, and post-processing affect noise, resolution, and diagnostic tasks.

Routine Equipment Checks

Practical checklist for daily and weekly CT checks students should observe or perform: detector warm-up, gantry calibration, basic phantom imaging, and logging results. Explains when to escalate anomalies to a supervisor or medical physicist.
