2.What principally determines radiographic spatial resolution?
3. Describe the equipment used in sensitometry.
4. What is the importance of processor quality control in an imaging department?
5. Have the manufacturer's representative help con- struct a characteristic curve from the data obtained from sensitometry and densitometry of a screen- film combination used in your department.
6. The intensity of light emitted by a viewbox is 1000. The intensity of light transmitted through the film is 1. What is the optical density of the film? Will it be light, gray, or black?
7. Base and fog densities on a given radiograph are 0.35. At densities 0.25 and 2 above base and fog densities, the characteristic curve shows log relative exposure values of 1.3 and 2. What is the average gradient?
