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.
What is a PET/CT scan? This advanced nuclear imaging technique combines positron emission tomography (PET) and computed tomography (CT) into once machine. A PET/CT scan reveals information about both the structure and function of cells and tissues in the body during a single imaging session. During a PET/CT scan, the patient is first injected with a glucose (sugar) solution that contains a very small amount of radioactive material. The substance is absorbed by the particular organs or tissues being examined. The patient rests on a table and slides into a large tunnel-shaped scanner.
