the science devoted to the measurement of the photographic properties of light-sensitive materials. Many important properties of photographic materials can be evaluated by means of this curve. ...

What is the purpose of sensitometry?

In radiation therapy, a sensitometric technique can be used for the determination of the proper characteristic curve for a film which can be placed beneath the patient before radiation treatment and removed afterwards so that an image of the anatomy actually irradiated is obtained.

What is the equipment used in sensitometry?

Describe the equipment used in sensitometry. A sensitometer or a combination of optical step-wedge and a densitometer, which measure OD, is needed to construct the characteristic curve.
