Product information “Lung Cancer Screening Model”
This Phantom 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 dif cult 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.
The model consists of a life size torso with arm up position and has the following internal structures:
Bones
Simulated tumors on sections of three lung area:
Apical portion of the lungs
Bifurcation of the trachea
Base of lungs
Dose meter hole (13 mm dia., on the central axis of the phantom)
1 8-step linearity phantom
8 steps of 30mm dia. density samples are embedded
