Radiation Physics Short Answer Questions

Answer each question with a minimum of 75 words for each question. Please use Essentials of Radiographic Physics and Imaging, 2nd Edition (Chapter 9) for references.

1.  Why is visibility of atomic tissue dependent on the radiograph's optical density/brightness and contrast?

2. How does atomic tissue composition affect beam attenuation and subsequently the radiographic contrast produced after processing?

3. How do the manufactured film speed, contrast, and latitude affect its response to radiation exposure?

4. How does a film's sensitometric characteristics relate to exposure technique selection and image quality?

5. Why is a good quality radiograph image also dependent on its recorded detail/spatial resolution and distortion?

6. What are the advantages and disadvantages of converting an analog film image into a digital image?

7. What are the benefits of displaying a radiographic image on a computer monitor?

8. How do the effects of quantum noise and scatter differ between digital and film screen imaging?
