iCT Learn is a comprehensive CT imaging education and clinical reference app designed for radiographers, radiologists, and medical imaging students. Built by a practising radiographer, iCT Learn bridges the gap between textbook knowledge and real-world CT practice - covering everything from fundamental physics to hands-on protocol optimisation. - LEARN - · CT Physics: X-ray attenuation, Hounsfield Units, beam geometry · Reconstruction: FBP, Iterative (IR), and Deep Learning (DLR) algorithms · Helical CT and Multi-Detector CT (MDCT) principles · Detailed accordion-style topic cards with formulae and clinical notes - REFERENCE - · 25 clinical CT protocols (Head, Chest, Abdomen, Cardiac, Vascular, Spine, Paediatric and more) · 34 tissue HU values across 7 categories · 20 windowing presets (Brain, Lung, Abdomen, Bone, Vascular) · Contrast media protocols, adverse reaction management, and contraindications · ARPANSA 2020 Diagnostic Reference Levels (CTDIvol and DLP) · Reconstruction kernel comparison: GE, Siemens, Canon, and Philips - INTERACTIVE TOOLS - · Dose Simulator: adjust kVp, mAs, Pitch, and patient size - see CTDI, noise, and SNR update in real time · HU Windowing Simulator: drag WW/WL sliders and watch tissue visibility change live · Artifact Pattern Guide: 7 major artifacts visualised with SwiftUI Canvas diagrams - Beam Hardening, Metal, Motion, Ring, Partial Volume, Aliasing, and Noise · Parameter Interaction Matrix: understand how kVp, mAs, Pitch, Kernel, and FOV affect dose, noise, contrast, and speed - QUIZ - · 12 self-assessment questions covering principles, parameters, and artifacts · Instant feedback with detailed explanations · Score tracking with wrong-answer review - DESIGNED FOR PROFESSIONALS - · Dark navy interface optimised for clinical environments · All content sourced from ARPANSA, ACR, ESUR, RANZCR, and peer-reviewed literature · Educational use only - does not provide medical advice iCT Learn is part of the Irradiated Solution clinical education series, developed in Melbourne, Australia.
