Organ absorbed doses from lateral cephalometric radiology were also measured using thermoluminescence detectors (TLDs) and an adult anthropomorphic phantom specially design for dosimetric study in dental radiology. Effective doses were then calculated using three different techniques where the salivary gland and brain tissue were given

Absorbed dose is defined as the amount of energy deposited by ionizing radiation in a substance. Absorbed dose is given the symbol D. The absorbed dose is usually measured in a unit called the gray (Gy), which is derived from the SI system. The non-SI unit rad …

Absorbed dose radiology

General term used to denote mean absorbed dose or effective dose. The particular Absorbed dose is a measure of the energy deposited per unit mass of tissue. The SI units are Gray (Gy) which is 1 6 Dec 2019 The rem is calculated by multiplying the absorbed dose (rad) by a quality (Q) For a detailed listing of the radiation doses of medical imaging Absorbed Dose. Radiation exposure is measured in an international (SI) unit called the gray (Gy).
