Handbook of Medical Radiography — Draft Text Preface This handbook provides concise, practical guidance for radiography students and practicing radiologic technologists. It covers fundamentals of x‑ray production, imaging techniques, patient care, radiation safety, image quality, and common procedures. Emphasis is on evidence‑based protocols, clinical decision making, and ethical practice. Chapter 1 — Introduction to Medical Radiography

Definition and scope of radiography. Roles and responsibilities of the radiographer. Overview of imaging modalities (plain radiography, fluoroscopy, CT, MRI, ultrasound, nuclear medicine) and when radiography is indicated. History and development of diagnostic radiology.

Chapter 2 — Radiation Physics and X‑Ray Production

Nature of ionizing radiation: photons, attenuation, interaction with matter (photoelectric effect, Compton scatter). X‑ray tube components and function: cathode, anode, focal spot, filtration, collimation. Production of x‑rays: thermionic emission, acceleration of electrons, characteristic and bremsstrahlung radiation. Beam quality and quantity: kVp, mA, exposure time, mAs, half‑value layer (HVL).

Chapter 3 — Radiation Biology and Safety

Biological effects of ionizing radiation: stochastic vs deterministic effects. Radiation dose units: gray (Gy), sievert (Sv), rad, rem; effective dose and organ doses. ALARA principle and optimization strategies. Shielding, protective equipment, distance, and time management. Regulatory limits and monitoring (dosimeters), pregnancy considerations.

Chapter 4 — Image Formation and Quality

Image receptor types: film‑screen, computed radiography (CR), digital radiography (DR). Factors affecting image quality: spatial resolution, contrast, noise, artifacts. Image processing, post‑processing, and PACS integration. Quality assurance and control tests for equipment and imaging chain.

Chapter 5 — Radiographic Technique and Positioning

Principles of positioning: alignment, central ray, anatomical markers, immobilization. Standard projections for head, chest, abdomen, spine, skull, pelvis, extremities. Technique charts: suggested kVp, mAs ranges, grids, focal spot, SID/FFD. Pediatric and geriatric modifications.

Chapter 6 — Contrast Media and Special Procedures

Types of contrast agents: iodinated contrast, barium sulfate, air/CO2. Indications, contraindications, and adverse reactions. Contrast administration techniques: oral, rectal, intravenous, intra‑articular. Fluoroscopic examinations: barium studies, intravenous urography, angiography basics.
