Final answer:
The measurement of radiation dose that accounts for helical studies on multi-row detector scanners and considers the total volume of irradiated tissue is the Dose-length product (DLP).
Step-by-step explanation:
The measurement of radiation dose that accounts for helical studies on multi-row detector scanners and considers the total volume of irradiated tissue is the Dose-length product (DLP).
The Dose-length product (DLP) takes into account the total length of tissue that is exposed to radiation. It is calculated by multiplying the computed tomography dose index (CTDI) by the scan length. DLP is measured in mGy·cm.
For example, if a multi-row detector scanner has a CTDI of 5 mGy and the scan length is 20 cm, then the DLP would be 100 mGy·cm.
