Lung Cancer Screening CT Phantom LSCT0001 is a CT phantom developed to facilitate optimizing the radiation dose and other scanning conditions for Lung Cancer Screening CT examination with Helical CT or MDCT, which is aiming at early detection of lung cancers. As the screening is usually done on healthy people, the necessity of minimizing the exposure while maximizing the image quality is considered to be particularly high. The phantom is designed to set conditions for detection of small early lung cancers such as GGA, which are difficult to be found by plain X-ray. Anthropologic structure of the phantom provides life-like images allowing operators visual evaluation, while quantitative evaluation on radiation dose and density curve of the image can be done stimulatory with a single scanning. Unique phantom dedicated for optimizing lung cancer CT screening conditions, as well as setting the standard conditions between multiple equipments or facilities for mass screening. Original human tissue substitute material creates life-like artifact under CT scanning Simulated GGA type tumors are embedded on three main sections of both lungs. Dose meter holder on the central axis of the phantom allows housing a pencil type chamber dose meter. 8-step cylindrical linearity phantom to control density curve as a scale can be attached to the chest phantom base.
