Digital Imaging in Radiology — Computed Radiography (CR), Digital Radiography (DR) & Image Quality Parameters | Lecture 5 | RadSound Physics Series

Step into the modern world of digital radiology with Dr. Muhammad Jafar in Lecture 5 of the RadSound Radiology Physics Series.
This session breaks down the evolution from film-screen radiography to computed (CR) and digital radiography (DR) — the technologies that revolutionized medical imaging.

With high-quality visuals and clear explanations, this lecture explores how digital detectors, pixels, and image processing redefine radiographic quality — from physics to clinical precision.

Through cinematic visuals and simple explanations, discover how energy, matter, and technology converge to create every X-ray image — from chest radiographs to digital DR systems.

🩻 In This Lecture, You’ll Learn:

The X-ray imaging chain: From tube output to final image

Differential attenuation and how contrast is created

The journey of photons — absorption, scatter, and transmission

The difference between primary and remnant beams

Fundamentals of image sharpness, contrast, and noise

The role of scatter control and beam filtration

How physics defines diagnostic clarity
🎯 Perfect For:
Radiology Residents • FRCR / MD Candidates • Radiographers • Medical Students • Imaging Educators
