New technology avoids these delays by using Volumetric CT which combines continuous rotation and continuous radiation data collection with continuous patient table transportation. The data obtained can be submitted directly to the image reconstruction process resulting in 3D images of the anatomical site. Individual anatomical scans can be used to prescribe the radiation dose to the tumor site with minimal exposure to critical surrounding normal tissues. Typical successive scans of the upper chest. The slice thickness is 5 mm.
Dark areas are lung tissue and light areas image the heart.
