iCTlearn
CT Education,Clinical Ref
$4.99 · Designed for iPad. Not verified for macOS.
Now with CT Generations (1st Gen to PCCT), full clinical reference, interactive dose simulator, and HU windowing tool. Built by a radiographer, for radiographers.
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

CT Generations - 1st Gen to PCCT
Learn how CT scanner technology evolved across five generations, from the original 1971 EMI pencil-beam scanner to the latest photon-counting CT. Each generation includes scan geometry diagrams, clinical significance, and current use status.
MDCT Evolution timeline - single-slice helical (1990) through to the Siemens NAEOTOM Alpha (2021), with detector row coverage and key clinical milestones.
Clinical Reference section - 25 CT protocols, 34 tissue HU values, 20 window presets, contrast media guide, ARPANSA 2020 DRL table, and reconstruction kernel comparison across GE, Siemens, Canon, and Philips.
Interactive Tools - real-time dose simulator (kVp / mAs / Pitch / patient size), HU windowing simulator with tissue visibility, and 7 artifact pattern diagrams drawn with SwiftUI Canvas.
