The relationship between dose at any depth from a beam of radiation compared with the dose at the entrance from that beam is a measure of the depth dose characteristics.
The actual amount of radiation exposure at a specific point below the surface of the body.
The depth dose corresponds to the radiation dosage administered within the tissues precisely at the designated point of concern. Essential considerations for evaluating the depth dose encompass determining the desired tissue depth, kilovoltage settings, filtration methods, and field dimensions. Typically quantified in units of rad (radiation absorbed dose).
