X-Ray Imaging | Chapter 20 Medical Physics | Class 12 Physics New Syllabus Punjab Boards

X-Ray Imaging | Attenuation, Image Contrast and Contrast Media | Chapter 20 Medical Physics | Class 12 Physics X-Ray Imaging | 12th Class Physics | Chapter 20 Medical Physics Long Question: Explain how attenuation of X-rays by different tissues creates contrast in the resulting image. Include an example. In this lecture, we will study X-Ray Imaging and understand how X-rays interact with different body tissues to produce clear medical images. The lecture covers attenuation of X-rays, image intensifiers, contrast in X-ray images, and the role of contrast media in improving the visibility of internal body structures. Topics Covered in This Lecture: Attenuation of X-rays and its definition Interaction of X-rays with atoms and ionization Exponential decrease in X-ray intensity Image intensifiers and their role in real-time X-ray imaging Contrast in X-ray images Difference between hard X-rays and soft X-rays Contrast media and their importance in medical imaging Examples of contrast media: Iodine and Barium Explanation of how different tissues create contrast in X-ray images Complete solution of the textbook exercise long question with the example of bones and soft tissues This Lecture Is Helpful For: 12th Class Physics Students Intermediate Part 2 Physics Students FSc Part 2 Physics Students ICS Part 2 Physics Students Subscribe to the channel for more Class 12 Physics lectures, conceptual explanations, and complete chapter-wise preparation according to the Punjab Board syllabus. #XRayImaging #Chapter20MedicalPhysics #Class12Physics
