Obtaining good. fusion splices is much easier today, due to continued improvements to the fusion splice equipment, procedures and. practices, in addition to the evolutionary improvements in controlling optical fiber geometries. As a result, losses.
In CT, the total amount of radiation incident on the patient, known as the DLP, is the product of the CTDIvol and scan length (in centimeters) and is measured in milligray-centimeters.
A Single Photon Emission Computed Tomography (SPECT) scan is a type of nuclear imaging test that shows how blood flows to tissues and organs.
