1. General information about the use of intensifying screens in radiology, and how films intended for use with intensifying screens differ from non-screen films.

2. A discussion of film sensitivity/speed, and the defining equation for this parameter.

3. Using the equations from # 2 and # 3 above, and the equation I = I0 e-μd, derive the equation for the ratio of sensitivity of two films (call them 1 and 2) as a function of tube voltage, tube current, source-to-film distance, exposure time, and linear attenuation coefficient and thickness of the object that produces an image with an optical density of fog level + 1 on the film.

4. A brief introduction on computed radiography, IP construction, and readout.

5. Describe the image receptor response curve for CR.
