Radiotherapy markers are made of materials that can be seen in CT images, aiming to determine the exact location of radiation in different treatment sessions. RTE markers are made up of non-metallic and latex-free materials that do not produce artifacts in CT images. The thicknesses provided in these markers are suitable for the slices with thickness of 5 mm and 3 mm in CT scan, which makes them suitable for different techniques in radiotherapy. RTE CT scan markers are offered in 2, 2.5, and 3 mm diameters.
